Installing Slackware 10.1 on a PC110

2006-07-25T20:45:56Z

Ed: /* X.Org 6.8.1 */

== Summary ==

This article describes how to configure Slackware 10.1 on a [[PC110]], with a [http://www.hgst.com/hdd/micro/overvw.htm 4GB Hitachi Microdrive] in one PCMCIA type II slot, a wireless network adapter in the other PCMCIA slot, as well as configuration settings for the [[CT-65535|video hardware]], the built-in peripheral devices including the pointing stick and touch pad, the modem and [[IrDA]] serial ports, the sound hardware, and the [[Power Management|power management]] features.

=== What works ===

* 4GB Hitachi Microdrive in a PCMCIA slot, from where the root filesystem is mounted
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* X.Org 6.8.1
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Occasional video corruption when switching from X to console
* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unknown whether the PC110 can suspend to disk at all)
* Floppy drive

</pre>

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/
root@carrot:~# cp /lib/libblkid.so.1 /mnt/lib/
root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the 4GB Hitachi Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>
ati0
Ver. 1.04

ati1

at&v
ACTIVE PROFILE: E1 M1 Q0 T V1 X4 &C1 &D2 &K3 &Q0 &S0 &T0 S00:000 S02:043

OK
</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==APM==

===[[Standby mode]]===

The BIOS takes care of entering standby mode and turning off the display backlight when running on battery power. The backlight stays on when connected to AC power.

===[[Sleep mode]]===

The system can be suspended by pressing {{key|Fn}}{{key|F4}}, or by closing the lid. Opening the lid, or pressing {{key|Fn}}, wakes the machine up again.

{{NOTE|It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake the disk up properly after a suspend/resume cycle, whereas the Linux IDE driver does.}}

Use the spare space on {{path|/dev/hda}}, mounted at {{path|/boot}} to keep a few handy binaries available even when {{path|/}}, the disk, is unavailable:
<pre>

</pre>

{{path|/boot/apmd/bin/apmd_proxy}} is a script called by <tt>apmd</tt> immediately before going to sleep, and again immediately after waking up. Some experimentation has resulted in the following script:

<pre>
#!/boot/apmd/bin/ash.static

# Make sure everything is flushed to the disk before suspending,
# and tell the disk to spin down.

LD_SO=/boot/apmd/lib/ld-linux.so.2
LD_LIBRARY_PATH=/boot/apmd/lib

case "$1" in
suspend)
$LD_SO --library-path $LD_LIBRARY_PATH /boot/apmd/bin/sync

$LD_SO --library-path $LD_LIBRARY_PATH /boot/apmd/bin/sync
$LD_SO --library-path $LD_LIBRARY_PATH /boot/apmd/bin/hdparm -f /dev/hdc
$LD_SO --library-path $LD_LIBRARY_PATH /boot/apmd/bin/hdparm -Y /dev/hdc
;;

resume)
# The IDE disk driver will wake the disk up again if it is properly stopped before suspending.
;;
esac
</pre>

Edit {{path|/etc/rc.d/rc.M}} to tell <tt>apmd</tt> where to find the script to execute.

<pre>
# Start APM or ACPI daemon.
# If APM is enabled in the kernel, start apmd:
if [ -e /proc/apm ]; then
if [ -x /usr/sbin/apmd ]; then
echo "Starting APM daemon: /usr/sbin/apmd"
/usr/sbin/apmd -P /boot/apmd/bin/apmd_proxy
fi
elif [ -x /etc/rc.d/rc.acpid ]; then # otherwise, start acpid:
. /etc/rc.d/rc.acpid start
fi
</pre>

===[[Hibernation mode]]===

Although the F12 key has a symbol on it that suggests suspending to disk, {{key|Fn}}{{key|F12}} does nothing.

==X.Org 6.8.1==

Turn off "Font Window" in the BIOS memory settings.

[[CT-65535|Here]] is a working {{path|xorg.conf}}. Note that

<pre>
Option "SWCursor"
</pre>

is essential: configured to use the default hardware cursor, X will fail to start, and will just show a black screen and use 100% CPU until it's killed.

The PC110 has enough video RAM to display 800x600 and 256 colours, either using a virtual desktop and a 640x480 viewport on the computer's own display, or full-screen using an external monitor connected to the VGA port on the port replicator. The appropriate Modeline to use depends on the desired settings for the external monitor.

Using [http://www.jfc.org.uk/software/lwm.html <tt>lwm</tt>] is a good way to make the most of the PC110's limited memory. Finding button 2 on the mouse is a bit tricky, and so is accurately moving the pointer to a window frame, so

<pre>
lwm*button1: xterm
lwm*focus: click
</pre>

makes a good addition to {{path|~/.Xresources}}.

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

Installing Slackware 10.1 on a PC110

2006-07-25T20:45:11Z

Ed: /* Kernel configuration */

== Summary ==

This article describes how to configure Slackware 10.1 on a [[PC110]], with a [http://www.hgst.com/hdd/micro/overvw.htm 4GB Hitachi Microdrive] in one PCMCIA type II slot, a wireless network adapter in the other PCMCIA slot, as well as configuration settings for the [[CT-65535|video hardware]], the built-in peripheral devices including the pointing stick and touch pad, the modem and [[IrDA]] serial ports, the sound hardware, and the [[Power Management|power management]] features.

=== What works ===

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the 4GB Hitachi Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>
ati0

OK
</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

===[[Standby mode]]===

The BIOS takes care of entering standby mode and turning off the display backlight when running on battery power. The backlight stays on when connected to AC power.

===[[Sleep mode]]===

The system can be suspended by pressing {{key|Fn}}{{key|F4}}, or by closing the lid. Opening the lid, or pressing {{key|Fn}}, wakes the machine up again.

{{NOTE|It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake the disk up properly after a suspend/resume cycle, whereas the Linux IDE driver does.}}

Use the spare space on {{path|/dev/hda}}, mounted at {{path|/boot}} to keep a few handy binaries available even when {{path|/}}, the disk, is unavailable:
<pre>

{{path|/boot/apmd/bin/apmd_proxy}} is a script called by <tt>apmd</tt> immediately before going to sleep, and again immediately after waking up. Some experimentation has resulted in the following script:

<pre>
#!/boot/apmd/bin/ash.static

# Make sure everything is flushed to the disk before suspending,
# and tell the disk to spin down.

LD_SO=/boot/apmd/lib/ld-linux.so.2

;;

resume)
# The IDE disk driver will wake the disk up again if it is properly stopped before suspending.
;;
esac
</pre>

Edit {{path|/etc/rc.d/rc.M}} to tell <tt>apmd</tt> where to find the script to execute.

<pre>
# Start APM or ACPI daemon.
# If APM is enabled in the kernel, start apmd:
if [ -e /proc/apm ]; then
if [ -x /usr/sbin/apmd ]; then
echo "Starting APM daemon: /usr/sbin/apmd"
/usr/sbin/apmd -P /boot/apmd/bin/apmd_proxy
fi
elif [ -x /etc/rc.d/rc.acpid ]; then # otherwise, start acpid:
. /etc/rc.d/rc.acpid start
fi
</pre>

===[[Hibernation mode]]===

Although the F12 key has a symbol on it that suggests suspending to disk, {{key|Fn}}{{key|F12}} does nothing.

==X.Org 6.8.1==

Turn off "Font Window" in the BIOS memory settings.

[[CT-65535|Here]] is a working {{path|xorg.conf}}. Note that

<pre>
Option "SWCursor"
</pre>

is essential: configured to use the default hardware cursor, X will fail to start, and will just show a black screen and use 100% CPU until it's killed.

The PC110 has enough video RAM to display 800x600 and 256 colours, either using a virtual desktop and a 640x480 viewport on the computer's own display, or full-screen using an external monitor connected to the VGA port on the port replicator. The appropriate Modeline to use depends on the desired settings for the external monitor.

Using [http://www.jfc.org.uk/software/lwm.html <tt>lwm</tt>] is a good way to make the most of the PC110's limited memory. Finding button 2 on the mouse is a bit tricky, and so is accurately moving the pointer to a window frame, so

<pre>
lwm*button1: xterm
lwm*focus: click
</pre>

makes a good addition to {{path|~/.Xresources}}.

Installing Slackware 10.1 on a PC110

2006-07-25T20:43:19Z

Ed: /* Summary */

== Summary ==

This article describes how to configure Slackware 10.1 on a [[PC110]], with a [http://www.hgst.com/hdd/micro/overvw.htm 4GB Hitachi Microdrive] in one PCMCIA type II slot, a wireless network adapter in the other PCMCIA slot, as well as configuration settings for the [[CT-65535|video hardware]], the built-in peripheral devices including the pointing stick and touch pad, the modem and [[IrDA]] serial ports, the sound hardware, and the [[Power Management|power management]] features.

=== What works ===

* 4GB Hitachi Microdrive in a PCMCIA slot, from where the root filesystem is mounted
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* X.Org 6.8.1
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Occasional video corruption when switching from X to console
* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unknown whether the PC110 can suspend to disk at all)
* Floppy drive
<pre>
ed@carrot:~$ sudo mount -t msdos /dev/fd0h1440 /mnt/floppy/
mount: block device /dev/fd0h1440 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/fd0h1440,

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the 4GB Hitachi Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

OK
</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

===[[Standby mode]]===

The BIOS takes care of entering standby mode and turning off the display backlight when running on battery power. The backlight stays on when connected to AC power.

===[[Sleep mode]]===

The system can be suspended by pressing {{key|Fn}}{{key|F4}}, or by closing the lid. Opening the lid, or pressing {{key|Fn}}, wakes the machine up again.

{{NOTE|It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake the disk up properly after a suspend/resume cycle, whereas the Linux IDE driver does.}}

Use the spare space on {{path|/dev/hda}}, mounted at {{path|/boot}} to keep a few handy binaries available even when {{path|/}}, the disk, is unavailable:
<pre>

</pre>

{{path|/boot/apmd/bin/apmd_proxy}} is a script called by <tt>apmd</tt> immediately before going to sleep, and again immediately after waking up. Some experimentation has resulted in the following script:

<pre>
#!/boot/apmd/bin/ash.static

# Make sure everything is flushed to the disk before suspending,
# and tell the disk to spin down.

LD_SO=/boot/apmd/lib/ld-linux.so.2

;;

resume)
# The IDE disk driver will wake the disk up again if it is properly stopped before suspending.
;;
esac
</pre>

Edit {{path|/etc/rc.d/rc.M}} to tell <tt>apmd</tt> where to find the script to execute.

<pre>
# Start APM or ACPI daemon.
# If APM is enabled in the kernel, start apmd:
if [ -e /proc/apm ]; then
if [ -x /usr/sbin/apmd ]; then
echo "Starting APM daemon: /usr/sbin/apmd"
/usr/sbin/apmd -P /boot/apmd/bin/apmd_proxy
fi
elif [ -x /etc/rc.d/rc.acpid ]; then # otherwise, start acpid:
. /etc/rc.d/rc.acpid start
fi
</pre>

===[[Hibernation mode]]===

Although the F12 key has a symbol on it that suggests suspending to disk, {{key|Fn}}{{key|F12}} does nothing.

==X.Org 6.8.1==

Turn off "Font Window" in the BIOS memory settings.

[[CT-65535|Here]] is a working {{path|xorg.conf}}. Note that

<pre>
Option "SWCursor"
</pre>

is essential: configured to use the default hardware cursor, X will fail to start, and will just show a black screen and use 100% CPU until it's killed.

The PC110 has enough video RAM to display 800x600 and 256 colours, either using a virtual desktop and a 640x480 viewport on the computer's own display, or full-screen using an external monitor connected to the VGA port on the port replicator. The appropriate Modeline to use depends on the desired settings for the external monitor.

Using [http://www.jfc.org.uk/software/lwm.html <tt>lwm</tt>] is a good way to make the most of the PC110's limited memory. Finding button 2 on the mouse is a bit tricky, and so is accurately moving the pointer to a window frame, so

<pre>
lwm*button1: xterm
lwm*focus: click
</pre>

makes a good addition to {{path|~/.Xresources}}.

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the 4GB Hitachi Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

===[[Standby mode]]===

The BIOS takes care of entering standby mode and turning off the display backlight when running on battery power. The backlight stays on when connected to AC power.

===[[Sleep mode]]===

The system can be suspended by pressing {{key|Fn}}{{key|F4}}, or by closing the lid. Opening the lid, or pressing {{key|Fn}}, wakes the machine up again.

{{NOTE|It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake the disk up properly after a suspend/resume cycle, whereas the Linux IDE driver does.}}

Use the spare space on {{path|/dev/hda}}, mounted at {{path|/boot}} to keep a few handy binaries available even when {{path|/}}, the disk, is unavailable:
<pre>

</pre>

{{path|/boot/apmd/bin/apmd_proxy}} is a script called by <tt>apmd</tt> immediately before going to sleep, and again immediately after waking up. Some experimentation has resulted in the following script:

<pre>
#!/boot/apmd/bin/ash.static

# Make sure everything is flushed to the disk before suspending,
# and tell the disk to spin down.

LD_SO=/boot/apmd/lib/ld-linux.so.2

case "$1" in

;;

resume)
# The IDE disk driver will wake the disk up again if it is properly stopped before suspending.
;;
esac
</pre>

Edit {{path|/etc/rc.d/rc.M}} to tell <tt>apmd</tt> where to find the script to execute.

<pre>
# Start APM or ACPI daemon.
# If APM is enabled in the kernel, start apmd:
if [ -e /proc/apm ]; then
if [ -x /usr/sbin/apmd ]; then
echo "Starting APM daemon: /usr/sbin/apmd"
/usr/sbin/apmd -P /boot/apmd/bin/apmd_proxy
fi
elif [ -x /etc/rc.d/rc.acpid ]; then # otherwise, start acpid:
. /etc/rc.d/rc.acpid start
fi
</pre>

===[[Hibernation mode]]===

Although the F12 key has a symbol on it that suggests suspending to disk, {{key|Fn}}{{key|F12}} does nothing.

==X.Org 6.8.1==

Turn off "Font Window" in the BIOS memory settings.

[[CT-65535|Here]] is a working {{path|xorg.conf}}. Note that

<pre>
Option "SWCursor"
</pre>

is essential: configured to use the default hardware cursor, X will fail to start, and will just show a black screen and use 100% CPU until it's killed.

The PC110 has enough video RAM to display 800x600 and 256 colours, either using a virtual desktop and a 640x480 viewport on the computer's own display, or full-screen using an external monitor connected to the VGA port on the port replicator. The appropriate Modeline to use depends on the desired settings for the external monitor.

Using [http://www.jfc.org.uk/software/lwm.html <tt>lwm</tt>] is a good way to make the most of the PC110's limited memory. Finding button 2 on the mouse is a bit tricky, and so is accurately moving the pointer to a window frame, so

<pre>
lwm*button1: xterm
lwm*focus: click
</pre>

makes a good addition to {{path|~/.Xresources}}.

==APM==

Installing Slackware 10.1 on a PC110

2006-07-25T16:34:51Z

Ed: /* Miscellaneous */

== Summary ==
=== What works ===

* 4GB Hitachi Microdrive in a PCMCIA slot
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* X.Org 6.8.1
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Occasional video corruption when switching from X to console
* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unclear whether the PC110 can suspend to disk under any OS)
* Floppy drive

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/
root@carrot:~# cp /lib/libblkid.so.1 /mnt/lib/
root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the 4GB Hitachi Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555

</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --

Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

{{NOTE|It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake the disk up properly after a suspend/resume cycle, whereas the Linux IDE driver does.}}

Use the spare space on {{path|/dev/hda}}, mounted at {{path|/boot}} to keep a few handy binaries available even when {{path|/}}, the disk, is unavailable:
<pre>

{{path|/boot/apmd/bin/apmd_proxy}} is a script called by <tt>apmd</tt> immediately before going to sleep, and again immediately after waking up. Some experimentation has resulted in the following script:

<pre>

# Make sure everything is flushed to the disk before suspending,
# and tell the disk to spin down.

LD_SO=/boot/apmd/lib/ld-linux.so.2

;;

resume)
# The IDE disk driver will wake the disk up again if it is properly stopped before suspending.
;;
esac
</pre>

Edit {{path|/etc/rc.d/rc.M}} to tell <tt>apmd</tt> where to find the script to execute.

<pre>
# Start APM or ACPI daemon.
# If APM is enabled in the kernel, start apmd:
if [ -e /proc/apm ]; then
if [ -x /usr/sbin/apmd ]; then
echo "Starting APM daemon: /usr/sbin/apmd"
/usr/sbin/apmd -P /boot/apmd/bin/apmd_proxy
fi
elif [ -x /etc/rc.d/rc.acpid ]; then # otherwise, start acpid:
. /etc/rc.d/rc.acpid start
fi
</pre>

==X.Org 6.8.1==

Turn off "Font Window" in the BIOS memory settings.

[[CT-65535|Here]] is a working {{path|xorg.conf}}. Note that

<pre>
Option "SWCursor"
</pre>

is essential: configured to use the default hardware cursor, X will fail to start, and will just show a black screen and use 100% CPU until it's killed.

The PC110 has enough video RAM to display 800x600 and 256 colours, either using a virtual desktop and a 640x480 viewport on the computer's own display, or full-screen using an external monitor connected to the VGA port on the port replicator. The appropriate Modeline to use depends on the desired settings for the external monitor.

Using [http://www.jfc.org.uk/software/lwm.html <tt>lwm</tt>] is a good way to make the most of the PC110's limited memory. Finding button 2 on the mouse is a bit tricky, and so is accurately moving the pointer to a window frame, so

<pre>
lwm*button1: xterm
lwm*focus: click
</pre>

makes a good addition to {{path|~/.Xresources}}.

==APM==

Installing Slackware 10.1 on a PC110

2006-07-25T16:24:33Z

Ed: /* Boot sequence */

== Summary ==
=== What works ===

* 4GB Hitachi Microdrive in a PCMCIA slot
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* X.Org 6.8.1
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Occasional video corruption when switching from X to console
* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unclear whether the PC110 can suspend to disk under any OS)
* Floppy drive

</pre>

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/
root@carrot:~# cp /lib/libblkid.so.1 /mnt/lib/
root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the 4GB Hitachi Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]

Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ

without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

{{NOTE|It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake the disk up properly after a suspend/resume cycle, whereas the Linux IDE driver does.}}

Use the spare space on {{path|/dev/hda}}, mounted at {{path|/boot}} to keep a few handy binaries available even when {{path|/}}, the disk, is unavailable:

{{path|/boot/apmd/bin/apmd_proxy}} is a script called by <tt>apmd</tt> immediately before going to sleep, and again immediately after waking up. Some experimentation has resulted in the following script:

# The IDE disk driver will wake the disk up again if it is properly stopped before suspending.
;;
esac
</pre>

Edit {{path|/etc/rc.d/rc.M}} to tell <tt>apmd</tt> where to find the script to execute.

<pre>
# Start APM or ACPI daemon.
# If APM is enabled in the kernel, start apmd:
if [ -e /proc/apm ]; then
if [ -x /usr/sbin/apmd ]; then
echo "Starting APM daemon: /usr/sbin/apmd"
/usr/sbin/apmd -P /boot/apmd/bin/apmd_proxy
fi
elif [ -x /etc/rc.d/rc.acpid ]; then # otherwise, start acpid:
. /etc/rc.d/rc.acpid start
fi
</pre>

==X.Org 6.8.1==

Turn off "Font Window" in the BIOS memory settings.

[[CT-65535|Here]] is a working {{path|xorg.conf}}. Note that

<pre>
Option "SWCursor"
</pre>

is essential: configured to use the default hardware cursor, X will fail to start, and will just show a black screen and use 100% CPU until it's killed.

The PC110 has enough video RAM to display 800x600 and 256 colours, either using a virtual desktop and a 640x480 viewport on the computer's own display, or full-screen using an external monitor connected to the VGA port on the port replicator. The appropriate Modeline to use depends on the desired settings for the external monitor.

Using [http://www.jfc.org.uk/software/lwm.html <tt>lwm</tt>] is a good way to make the most of the PC110's limited memory. Finding button 2 on the mouse is a bit tricky, and so is accurately moving the pointer to a window frame, so

<pre>
lwm*button1: xterm
lwm*focus: click
</pre>

makes a good addition to {{path|~/.Xresources}}.

Installing Slackware 10.1 on a PC110

2006-07-25T16:21:27Z

Ed: /* X.Org 6.8.1 */

== Summary ==
=== What works ===

* 4GB Hitachi Microdrive in a PCMCIA slot
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* X.Org 6.8.1
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Occasional video corruption when switching from X to console
* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unclear whether the PC110 can suspend to disk under any OS)
* Floppy drive

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/
root@carrot:~# cp /lib/libblkid.so.1 /mnt/lib/
root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>

without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

{{NOTE|It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card.

Use the spare space on {{path|/dev/hda}}, mounted at {{path|/boot}} to keep a few handy binaries available even when {{path|/}}, the disk, is unavailable:

# The IDE disk driver will wake the disk up again if it is properly stopped before suspending.

</pre>

Edit {{path|/etc/rc.d/rc.M}} to tell <tt>apmd</tt> where to find the script to execute.

<pre>
# Start APM or ACPI daemon.
# If APM is enabled in the kernel, start apmd:

fi
elif [ -x /etc/rc.d/rc.acpid ]; then # otherwise, start acpid:

fi
</pre>

==X.Org 6.8.1==

Turn off "Font Window" in the BIOS memory settings.

[[CT-65535|Here]] is a working {{path|xorg.conf}}. Note that

<pre>
Option "SWCursor"
</pre>

is essential: configured to use the default hardware cursor, X will fail to start, and will just show a black screen and use 100% CPU until it's killed.

The PC110 has enough video RAM to display 800x600 and 256 colours, either using a virtual desktop and a 640x480 viewport on the computer's own display, or full-screen using an external monitor connected to the VGA port on the port replicator. The appropriate Modeline to use depends on the desired settings for the external monitor.

Using [http://www.jfc.org.uk/software/lwm.html <tt>lwm</tt>] is a good way to make the most of the PC110's limited memory. Finding button 2 on the mouse is a bit tricky, and so is accurately moving the pointer to a window frame, so

<pre>
lwm*button1: xterm
lwm*focus: click
</pre>

makes a good addition to {{path|~/.Xresources}}.

Installing Slackware 10.1 on a PC110

2006-07-25T11:38:31Z

Ed: /* X.Org 6.8.1 */

== Summary ==
=== What works ===

* 4GB Hitachi Microdrive in a PCMCIA slot
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* X.Org 6.8.1
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Occasional video corruption when switching from X to console
* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unclear whether the PC110 can suspend to disk under any OS)
* Floppy drive

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/
root@carrot:~# cp /lib/libblkid.so.1 /mnt/lib/
root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --

will fail to start, and will just show a black screen and use 100% CPU until it's killed.

Using [http://www.jfc.org.uk/software/lwm.html <tt>lwm</tt>] is a good way to make the most of the PC110's limited memory. Finding button 2 on the mouse is a bit tricky, and so is accurately moving the pointer to a window frame, so

<pre>

Installing Slackware 10.1 on a PC110

2006-07-25T11:35:45Z

Ed: /* Miscellaneous */

== Summary ==
=== What works ===

* 4GB Hitachi Microdrive in a PCMCIA slot
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* X.Org 6.8.1
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Occasional video corruption when switching from X to console
* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unclear whether the PC110 can suspend to disk under any OS)
* Floppy drive

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt

libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:

without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

{{NOTE|It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card.

Use the spare space on {{path|/dev/hda}}, mounted at {{path|/boot}} to keep a few handy binaries available even when {{path|/}}, the disk, is unavailable:

Installing Slackware 10.1 on a PC110

2006-07-25T11:25:20Z

Ed: /* What works */

== Summary ==

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>

Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --

Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>

libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

Installing Slackware 10.1 on a PC110

2006-07-25T11:21:35Z

Ed: /* Installation of Slackware 10.1 on a PC110 */

== Summary ==
=== What works ===

* 4MB Hitachi Microdrive in a PCMCIA slot
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unclear whether the PC110 can suspend to disk under any OS)
* Floppy drive
<pre>

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:

Installing Slackware 10.1 on a PC110

2006-07-25T11:20:11Z

Ed: /* Kernel configuration */

= Installation of Slackware 10.1 on a PC110 =
== Summary ==
=== What works ===

* 4MB Hitachi Microdrive in a PCMCIA slot
* PCMCIA Network adapters (3Com 3c589, Linksys WPC11 11Mbps 802.11b WLAN Card)
* Graphics adapter and accelerator ([[CT-65535]])
* Digitizer pad
* [[IrDA]]
* [[ES488]] Audio controller
* Modem
* Suspend/resume to RAM

=== What needs to be fixed ===

* Suspend to disk ({{key|Fn}}{{key|F12}} -- there is an appropriate symbol on the key, but it is unclear whether the PC110 can suspend to disk under any OS)
* Floppy drive
<pre>

</pre>

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used

root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard

mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

Installing Slackware 10.1 on a PC110

2006-07-25T01:07:25Z

Ed: /* WPA configuration */

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/
root@carrot:~# cp /lib/libblkid.so.1 /mnt/lib/
root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight, or perhaps a tool for scraping ice off a car window. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>
ati0

ACTIVE PROFILE: E1 M1 Q0 T V1 X4 &C1 &D2 &K3 &Q0 &S0 &T0 S00:000 S02:043

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

How to save memory

2006-07-25T00:52:48Z

Ed: /* Other tips */

{| width="100%"
|style="vertical-align:top;padding-right:20px;width:10px;white-space:nowrap;" | __TOC__
|style="vertical-align:top" |This page is meant as a collection of information on how to save memory to make Linux work reasonable on older system with limited amount of RAM.

Most distributions nowadays don't take much care about it anymore, so there are a lot of things you can do to save memory. To get a smoothly working linux environment on a low memory machine you will need to conciously choose a lot of aspects of your system, most importantly the graphical environment, desktop environment and applications. This page provides detailed information about these various optimization possibilities.
|}

==Alternative graphical environments==
{{Todo|...}}

==Streamlining the desktop environment==
The common Desktop environments GNOME and KDE are, in their modern state, focused more on features, integration, and beauty rather than on resource saving. Understandable, but running Linux on an older ThinkPad with limited RAM requires conscious and sensitive resource usage more than anything else. The good thing about Linux is that a lot of things stay adjustable and customizable. So lets see what we can do about desktops.

One of the most important things is to decide for one graphical widget library and stick with that when you are choosing your desktop environment and applications. Having several toolkits in use means more libraries being loaded and hence more memory being used by those. Possibilities are:
* [http://www.fltk.org/ FLTK]
* [http://www.fox-toolkit.org/ FOX toolkit]
* [http://www.gnustep.org GNUstep toolkit]
* [http://www.gtk.org/ GTK] <tt>(not recommended, use GTK 2 if possible)</tt>
* [http://www.gtk.org/ GTK 2]
* [http://www.lesstif.org/ Lesstif] / [http://www.openmotif.org/ OpenMotif]
* [http://www.trolltech.com/products/qt/index.html QT]
* [http://www.windowmaker.org/development-wings.html WINGs] <tt>(kind of a lightweight GNUstep toolkit, provided by the WindowMaker developers)</tt>
* [http://www.x.org/ X Toolkit]

Of those, at current state, there are enough applications for the X Toolkit, GTK, GTK 2 and QT to provide you with a solution for every task you should want.

===GNOME===
It's like with humans, the worst feature is in most cases also the best one. For GNOME it is probably the many little parts it consists of. Makes it hard to install, but enables one to customize the installation. So, the first thing you should do to streamline GNOME is not to launch it. Sound stupid? Well, lets have a look.

GNOME is basically a set of libraries built around the GTK+ libs and extending its functionality. Add some nice little applications, a session manager, a panel, beautiful icons, and some other stuff and you have GNOME as you know it. Reversing those additions is what you can do to use GNOME applications on a machine that this desktop environment would normally take your nerves on.

The GNOME panel, the session manager, the desktop manager and the window manager are all parts of GNOME that eat a lot of memory for something that others can do in a maybe little less beautiful but much more resource saving way.
So first off configure your login manager not to launch gnome-session at login. If you are using GDM this is quite straight forward, you just need to add a different session script, launching your favorite window manager. See the list below and pick one, lets say i.e. WindowMaker. WindowMaker uses a desktop menu, a dock and a notification area to provide you with an organized way of launching applications and iconfying running ones. So we don't need a panel anymore. Also, think if you really need icons on your desktop. If you do, think about using something like ROX filer instead of nautilus for that. In any case, tell nautilus not to manage the desktop by default by unchecking the according setting within gconf-editor. To keep GNOME applications happy we would need to have gconf and gnome-settings-manager running at every session start. One way to do this is to either include them in your new session script. They both need to be running to make GNOME applications realize their settings properly.

===KDE===
{{Todo|...}}

===Alternative Desktop Environments===
First of all, it is important to notice that GNOME and KDE are not the only Desktop Environments around.
Other complete (featuring most of: window management, session management, desktop management, file management and panel) desktop environments are:
*[http://xfce.org/ XFCE] <tt>uses GTK 2</tt>
*[http://ede.sourceforge.net Equinox Desktop Environment] <tt>uses eFLTK, a modified version of FLTK</tt>
*[http://www.nongnu.org/antiright/ AntiRight Desktop Environment] <tt>uses LessTif / OpenMotif</tt>
*[http://foxdesktop.sourceforge.net/ FOX Desktop Environment] <tt>uses FOX Toolkit</tt>
*[http://www.gnustep.org/ GNUstep] <tt>provides it's own toolkit</tt>

But also, some Window Managers exceed the task of managing windows towards providing a functional workbench. See below for a list.

===Building your own Desktop===

====Window Manager====
If you want to build your own customized desktop, a good start is choosing the window manager of your liking.

Here's a list of some of them:
*including basic Desktop Environment functionality
**the [[Wikipedia:NextStep|NextStep]] alike ones
***[http://www.windowmaker.org/ WindowMaker] <tt>(probably the most widespread NextStep like WM)</tt>
***[http://www.afterstep.org/ AfterStep] <tt>(another one of those)</tt>
**the Blackbox-like ones
***[http://blackboxwm.sourceforge.net/ BlackBox]
***[http://fluxbox.sourceforge.net/ FluxBox] <tt>(tabbed windows, lighweight)</tt>
**others
***[http://www.icewm.org/ IceWM] <tt>(lightweight, widespread)</tt>
***[http://enlightenment.sourceforge.net/ Enlightenment] <tt>(lots of features and eye candy)</tt>
***[http://www.pekwm.org PekWM] <tt>(kind of a one man show, but feature rich and extremely customizable)</tt>
*pure WindowManagers
**[http://golem.sourceforge.net/ Golem]
**[http://home.earthlink.net/~lab1701/larswm/ LarsWM] <tt>(unique tiling Window Manager)</tt>
**[http://www.nongnu.org/ratpoison/ ratpoison] <tt>(modeled after gnu screen)</tt>
**[http://fvwm.org/ fvwm] <tt>(small but powerful)</tt>
**[http://www.jfc.org.uk/software/lwm.html lwm] <tt>(very small, and fast)</tt>
**[http://www.all-day-breakfast.com/wm2/ wm2] <tt>really small Window Manager</tt>

====Taskbar/Panel====
Another thing that especially users coming to Linux from the Windows world would probably like is a Panel or Taskbar.

Here's a collection of independant low resource panels:
*[http://www.chatjunkies.org/fspanel/ F***ing Small Panel] <tt>(doesn't use any toolkit)</tt>
*[http://freshmeat.net/projects/hpanel/ HPanel] <tt>(doesn't use any toolkit)</tt>
*[http://fbpanel.sourceforge.net/ fbpanel] <tt>(depends on GTK 2)</tt>
*[http://jodrell.net/projects/perlpanel Perl Panel] <tt>(depends on GTK 2, gnomevfs, perl)</tt>
*[http://www.gkrellm.net/ GKrellM] <tt>(depends on GTK 2, flexible plugin based skinable vertical panel)</tt>

====Desktop Pinboard====
Then, the next thing you might be looking for is how to get icons onto your desktop. Usually this is done by the file manager who displays the content of a special directory as icons on the desktop. See the File Manager section to follow this approach.

However, you might decide for a really lightwight file manager which doesn't offer this feature. In that case all hope is not lost, for there are also special programs specialized in desktop icon management. Such are:
* [http://idesk.sourceforge.net/ iDesk] <tt>(recent versions need imlib2 only)</tt>

====File Manager====
File Managers are the fourth really important compontent of a desktop environment. There are plenty out their ranging from resource hugs to really lightweight and slim ones.

File Managers come with three distinct general user interface approaches: the two pane gui, the spacial and the browser gui. The browser gui is the one the Windows Explorer starting from Windows 2000 uses as well as earlier versions of Nautilus. The spacial view is the one known from Windows 95 and more recent versions of Nautilus. The two pane view is know to many from Norten Commander, Directory Opus or your favorite FTP client.

==Choosing applications==
===Web Browser===
This is highly dependend on the way you use your browser, it's often worth it to try out all and just track general
memory usage. Remember that <tt>top</tt> and <tt>ps</tt> don't report correct memory usage, track totals only.

====Firefox====
Firefox is graphical web browser. One can install features like AdBlock and FlashClicktoplay which will decrease memory and
processor usage by hiding Flash and Java -adverts.

====Opera====
Opera is graphical web browser. You can easily enable/disable plug-ins and java (press F12) and decrease memory usage.
Opera uses QT as toolkit, so you may shave off some Mbytes off memory usage by using dynamically linked version if you use KDE.

====Konqueror====
Konqueror is graphical web browser. It's integrated with KDE and has several advanced features (esp. ca. KDE 3.5).
You may save some megabytes by using it instead of other browsers when using KDE.
It's not necessarily heavy even when used without running KDE.

====Dillo====
Dillo is minimalistic and very small graphical web browser.

====Elinks/Lynx====
elinks/lynx are both text mode web browsers. <tt>elinks</tt> handles tables and formatting much nicer than <tt>lynx</tt>.
Both go very easy on memory footprint.

{{Todo|...}}

==Disabling unneeded system deamons==
Another thing you can do to improve performance is to get rid of unneaded system daemons launched from your init scripts. Disable them by using the according configuration interface of your distro or by deleting links in the according runlevel directories (usually in <code>/etc/rc.d/</code>).

Daemons you usually don't need:
* httpd <tt>(Apache web server)</tt>
* mysqld <tt>(MySQL database server)</tt>
* smbd <tt>(SMB windows filesharing server)</tt>
* pppd <tt>(PPP server for connections through modems and serial lines)</tt>

==Adjusting filesystems==
You can also try to optimize memory usage by making sure that you have as little as possible of your filesystem residing in RAM. To do this make sure that the following mount points are set to reside on your harddisk in {{path|/etc/fstab}}.
* /dev (not possible if you use udev)
* /tmp

Also make sure that you mount filesystems with extensive usage with noatime parameter (mount -o remount,ro /...), which disabled access time writes every time you access some file. Note that many incremental backups needs atime to work, such backups will then behave like full backup everytime. This depends on backup systems.

==Other tips==
===Disk space===
When using Debian/Ubuntu/other derivative, use <tt>aptitude</tt> as package manager, and use it as soon as possible. Use it and only it to install and remove packages.

One of its most useful features is that it tracks packages you install and marks packages installed via dependency as such, so when you remove a package that is no longer used, or package updates and doesn't use a library anymore, that dependency will get uninstalled.

You can mark packages installed as automatically installed by hitting 'M' (uppercase m), it will be marked for deinstallation if it's not longer required.

You could also install <tt>localepurge</tt> wich will remove all unneeded locales and localized manpages for packages you install.

===System clock===
<tt>ntpd</tt> can occupy around 4MB of memory, which is a substantial proportion of many older systems' total. [http://chrony.sunsite.dk/ <tt>chrony</tt>] is a pair of programs that replace the standard <tt>ntp</tt> and require much less memory.

Installing Slackware 10.1 on a PC110

2006-07-25T00:43:00Z

Ed: /* Network */

==Kernel configuration==

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/
root@carrot:~# cp /lib/libblkid.so.1 /mnt/lib/
root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

===WPA configuration===

{{NOTE|WPA requires that the Prism3 card's station firmware is at least version 1.7.0. Newer firmware is available [http://www.red-bean.com/~proski/firmware/ here] and instructions for downloading it into the network card's flash memory using tools supplied as part of the [[hostap]] driver can be found [http://linux.junsun.net/intersil-prism/ here].}}
{{WARN|Unsuccessful attempts to reprogram the network card's flash memory may leave it in an unusable state, except as some sort of paperweight. WEP and unencrypted network configurations will work with whichever station firmware version your card already has; if you don't understand the instructions for installing newer firmware versions, or don't understand why you might want a newer version, don't do it.}}

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

===General wireless network configuration===

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}} (described in the next section).

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>

Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

{{NOTE|These instructions are intended for use with Slackware 10.1 plus Linux kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], rather than with any of the kernels included with the Slackware 10.1 distribution.

These instructions also describe how to configure the PC110 to boot from a 4MB Hitachi CompactFlash type II Microdrive, how to configure the PC110 to connect to a WPA-encrypted wireless network using a Prism3 chipset PCMCIA card, how to configure the PC110's various other peripheral devices, and how to set up X.Org.}}

The stock 2.4.29 Linux kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (do this overnight if you're compiling on the PC110 itself) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Install any other modules you may have ([[hostap]] wireless network card driver modules, for example) if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}}.

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

</pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0
Init3 = ATQ0V1E1S0=0&C1&D2S11=55+FCLASS=0
Phone = 555 555 5555
Username = name
Password = password
</pre>

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --
Mar 12 09:40:43 carrot -- MARK --
Mar 12 10:20:48 carrot -- MARK --
Mar 12 10:56:35 carrot -- MARK --
</pre>
messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

Installing Slackware 10.1 on a PC110

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}}.

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --

Installing Slackware 10.1 on a PC110

2006-07-25T00:06:56Z

Ed: /* Boot sequence */

==Kernel configuration==

''These instructions are intended for use with kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], and not with any of the kernels included with the Slackware 10.1 distribution.''

The stock kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (overnight, probably :-) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Reinstall
the <tt>hostap</tt> modules if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out

root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:

libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order. It's essential that the BIOS boot sequence doesn't include "PCMCIA", because if it does the BIOS will control the slot with the disk in, and <tt>pcmcia-cs</tt> will only control the one with the network card. The BIOS doesn't seem to be able to wake up the Hitachi 4MB Microdrive properly after a suspend/resume cycle, whereas the Linux IDE driver does.

{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Installing Slackware 10.1 on a PC110

2006-07-25T00:05:13Z

Ed: /* APM */

==Kernel configuration==

''These instructions are intended for use with kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], and not with any of the kernels included with the Slackware 10.1 distribution.''

The stock kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (overnight, probably :-) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Reinstall
the <tt>hostap</tt> modules if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order{{footnote|1}}.
{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}}.

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:
<pre>

The modem is ''really loud'', so <tt>ATM0</tt> would be a good start;
[http://open.nit.ca/wiki/index.php?page=WvDial <tt>wvdial</tt>] might be
useful too. {{path|/etc/wvdial.conf}} might look like:

<pre>
[Dialer Defaults]
Modem = /dev/modem
Baud = 57600
# The PC110 modem doesn't like spaces in command strings.
Init = ATZ
Init2 = ATX3M0

See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,

Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}}.

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

{{NOTE|The PC110 doesn't let you use all the serial ports at the same time: there are three serial devices and one two-channel UART. Here we configure the IrDA port and modem, since those are the two devices built into the computer itself (the ordinary DE9 wired serial port is located on the port replicator). The standard
serial port requires no configuration beyond initialisation of the driver.}}

In the BIOS, [http://www.basterfield.com/pc110/bios/serial.htm set the serial
ports] to "Infrared 1" (ttyS0) and "Modem 2" (ttyS1). The potentially most useful setting,
activating the serial port on the port replicator and IrDA at the same time and ignoring the
crappy modem altogether, is not available because these two devices share UART circuitry.

===IrDA===

The device files need to be created:

<pre>
mknod /dev/ircomm0 c 161 0
mknod /dev/ircomm1 c 161 1
mknod /dev/irlpt0 c 161 16
mknod /dev/irlpt1 c 161 17
mknod /dev/irnet c 10 187
chmod 666 /dev/ir*
</pre>

Put this in <tt>/etc/modules.conf</tt>:

<pre>
alias tty-ldisc-11 irtty
alias char-major-161 ircomm-tty
</pre>

Get the [http://sourceforge.net/project/showfiles.php?group_id=5616 user-space
IrDA tools] and install them.

{{cmdroot|irattach /dev/ttyS0 -s}} should load all the required modules, and start flashing
the red light.

===Modem===

The modem is "FAX Class2/2.0 9600bps, DATA 2400/MNP5, VOICE (no standard)", and
mostly undocumented. Finding suitable initialisation and command strings is left as an exercise
for the reader.

Here is the information it is prepared to tell us:

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

==APM==

==X.Org configuration==

Installing Slackware 10.1 on a PC110

2006-07-25T00:01:49Z

Ed: /* Serial ports */

==Kernel configuration==

''These instructions are intended for use with kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], and not with any of the kernels included with the Slackware 10.1 distribution.''

The stock kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (overnight, probably :-) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Reinstall
the <tt>hostap</tt> modules if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/

root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order{{footnote|1}}.
{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o

Installing Slackware 10.1 on a PC110

2006-07-24T23:50:18Z

Ed: /* Sound */

==Kernel configuration==

''These instructions are intended for use with kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], and not with any of the kernels included with the Slackware 10.1 distribution.''

The stock kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (overnight, probably :-) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Reinstall
the <tt>hostap</tt> modules if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)

root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory

/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order{{footnote|1}}.
{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o

/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}}.

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>
alias sound-slot-0 sb
alias midi opl3
options opl3 io=0x388
options sb io=0x220 irq=5 dma=1
alias sound sb
</pre>

==Touch pad==

The touch pad is fiddly and inconvenient to use, but it may as well be configured.

<pre>
mknod /dev/pc110pad c 10 9
</pre>
Run {{cmdroot|/usr/sbin/mouseconfig}} and choose a PS/2 mouse, in order to link
{{path|/dev/mouse}} to {{path|/dev/psaux}} and create {{path|/etc/rc.d/rc.gpm}}.

Edit {{path|/etc/rc.d/rc.gpm}} to invoke gpm in repeater mode: change both occurrences of

<pre>
/usr/sbin/gpm -m /dev/mouse -t ps2
</pre>
to
<pre>
/usr/sbin/gpm -R -tps2 -M -tps2 -m /dev/pc110pad -g1 -i500 -d8
</pre>

And in {{path|/etc/modules.conf}}:
<pre>
alias char-major-10-9 pc110pad
</pre>

==Serial ports==

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>

</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

The sound card is 8-bit, mono, and SoundBlaster compatible.

Put this in {{path|/etc/modules.conf}}:

<pre>

{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --

couple of error messages at boot time.

Installing Slackware 10.1 on a PC110

2006-07-24T23:45:53Z

Ed: /* Miscellaneous */

==Kernel configuration==

''These instructions are intended for use with kernel version [http://kernel.org/pub/linux/kernel/v2.4/linux-2.4.29.tar.bz2 2.4.29], and not with any of the kernels included with the Slackware 10.1 distribution.''

The stock kernel requires [http://www.mail-archive.com/kbuild-devel@lists.sourceforge.net/msg02111.html a patch] before {{cmduser|make config}} will produce a configuration appropriate for an i486. Alternatively, skip the {{cmduser|make config}} stage and use [[PC110Kernel2429Config|this configuration]].

Compile the kernel and modules (overnight, probably :-) and copy the kernel to
{{path|/boot/bzImage-2.4.29}}. Install the modules in {{path|/lib/modules/2.4.29}}. Reinstall
the <tt>hostap</tt> modules if {{cmdroot|make modules_install}} removes them.

==Boot sequence==

Booting with {{path|/}} on a PCMCIA device is a bit tricky. There are two ways to do it:

# Add "PCMCIA" to the start-up disk choices in the BIOS, or</li>
# Use an initial ram disk to load the pcmcia modules.</li>

The first option is easier -- the BIOS takes over the slot with the Microdrive in, and the other
one is free for other devices. This works for booting, but the BIOS doesn't seem to be able to wake
the disk up after a suspend-resume cycle. It used to work with the original type III PCMCIA
disk, so it seems the Microdrive needs to be prodded in a different way to revive it.

The solution is to create a PCMCIA-aware <tt>initrd</tt> to initialise the PCMCIA controller
before {{path|/}} is mounted. {{path|/sbin/pcinitrd}}, part of the <tt>pcmcia-cs</tt>
package, will do most of the work. The ramdisk it creates uses <tt>ash</tt> to execute {{path|/linuxrc}},
so make sure <tt>ash</tt> is installed before running <tt>pcinitrd</tt>.
The ramdisk created by <tt>pcinitrd</tt> isn't quite complete; add the missing libraries
and binaries like so:

<pre>
root@carrot:~# /sbin/pcinitrd initrd
2400+0 records in
2400+0 records out
mke2fs 1.35 (28-Feb-2004)
1836K/2357K used
root@carrot:~# mount -o loop initrd /mnt/
root@carrot:~# cp /sbin/insmod.old /mnt/bin/
root@carrot:~# cp /lib/libblkid.so.1 /mnt/lib/
root@carrot:~# cp /lib/libuuid.so.1 /mnt/lib/
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/pcmcia/i82365.o /mnt/lib/pcmcia
root@carrot:~# cp /lib/modules/2.4.29/kernel/drivers/ide/legacy/ide-cs.o /mnt/lib/pcmcia
root@carrot:~# ldconfig -v -r /mnt
ldconfig: Can't open configuration file /etc/ld.so.conf: No such file or directory
ldconfig: Can't stat /usr/lib: No such file or directory
/lib:
libuuid.so.1 -> libuuid.so.1
libblkid.so.1 -> libblkid.so.1
ld-linux.so.2 -> ld-linux.so.2
libc.so.6 -> libc.so.6
root@carrot:~# umount /mnt/
root@carrot:~# gzip initrd
root@carrot:~# cp initrd.gz /boot/initrd
</pre>

Set the [http://www.basterfield.com/pc110/bios/startup.htm BIOS startup
sequence] to "FDD-1", "HDD-1", in that order{{footnote|1}}.
{{path|/boot}} is mounted on {{path|/dev/hda1}}, the 4MB internal flash disk (Hard
disk 1 in the BIOS).

{{path|/etc/lilo.conf}} should look like

<pre>
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=slackware-10.1

image=/boot/bzImage-2.4.29
label=slackware-10.1
inirtd=/boot/initrd
read-only
root=/dev/hdc2
append="hdd=noprobe"
</pre>

LILO version 22.5.9, as installed with Slackware 10.1, complains about the <tt>linear</tt>
option, but there is no immediate need to take it out; it's always been there and it's always worked.
{{path|/dev/hda}} isn't bigger than 8.4GB, so using <tt>lba32</tt> instead wouldn't gain anything.

<tt>append="hdd=noprobe"</tt> prevents the IDE driver probing for a slave device
on the second IDE interface (the other PCMCIA slot); nothing bad happens if the probe takes place, but the boot
process hangs for a few seconds. We know there's nothing there, so there's no point looking.

=={{path|/etc/fstab}}==

{{path|/etc/fstab}} looks like this:

<pre>
/dev/hda1 /boot ext2 ro 1 2
/dev/hdc2 / ext3 defaults 1 1
/dev/fd0 /mnt/floppy auto noauto,owner 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
/dev/hdc1 swap swap defaults 0 0
</pre>

{{HINT|Mounting / with option "noatime" might be a good idea.}}

{{HINT|For NFS to work properly, make sure /etc/rc.d/rc.portmap is chmod 755.}}

==PCMCIA configuration==

The second serial port and the sound card use IRQs 3 and 5 respectively, and the
touch pad uses IRQ 10. Edit {{path|/etc/pcmcia/config.opts}} to prevent any PCMCIA devices
being assigned these IRQs:

<pre>
# Second built-in serial port
exclude irq 3
# Sound card
exclude irq 5
# Touch pad
exclude irq 10
</pre>

Make sure the {{path|/etc/pcmcia/config.opts}} found in the initial ramdisk
{{path|/boot/initrd}} has the same IRQs excluded.

==Network==

{{NOTE|This section describes how to configure [[Hostap]] to use a Zyxel ZyAir B-100 11Mbps 802.11b WLAN card. This card uses the Prism3 chipset, and identifies itself as a "Linksys WPC11 11Mbps 802.11b WLAN Card". The following guidelines may work with other Prism3 chipset WLAN PCMCIA cards, but have only been tested with the card named above.}}

[[Hostap]] isn't included with the <tt>pcmcia-cs</tt> distribution, so needs adding to the configuration files. Edit {{path|/etc/pcmcia/config}} and add this to the "Device driver definitions"
section at the top of the file:

<pre>
device "hostap_cs"
class "network" module "hostap_cs"
</pre>

and in the "Wireless network adapters" section (about half way through the file) change
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "orinoco_cs"
</pre>
to
<pre>
card "Linksys WPC11 11Mbps 802.11b WLAN Card"
manfid 0x0274, 0x1613
bind "hostap_cs"
</pre>

Compile the driver modules and install them in {{path|/lib/modules/}}:
<pre>
/lib/modules/2.4.29/kernel/drivers/net/pcmcia/hostap_cs.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_ccmp.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_tkip.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_crypt_wep.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_pci.o
/lib/modules/2.4.29/kernel/drivers/net/wireless/hostap_plx.o
/lib/modules/2.4.29/pcmcia/hostap_cs.o
</pre>
({{path|/lib/modules/2.4.29/pcmcia/hostap_cs.o}} is a symbolic link to
{{path|../kernel/drivers/net/pcmcia/hostap_cs.o}}).

Build and install <tt>wpa_supplicant</tt> according to the instructions in the source package.
See its README file for details. Configure <tt>wpa_supplicant</tt> as described in the README,
and summarised here.


Create {{path|/etc/wpa_supplicant.conf}}:
<pre>
network={
ssid="<the network name>"
scan_ssid=1
key_mgmt=WPA-PSK
psk="<the key>"
}
</pre>

Add the following block to the end of 'start' action handler in
{{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -i$DEVICE
fi
</pre>

Separate 'restart', 'resume', 'check' and 'suspend' action handlers from 'stop', and
add the following block to the end of 'stop' action handler in {{path|/etc/pcmcia/wireless}}:

<pre>
if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
killall wpa_supplicant
fi
</pre>

Edit {{path|/etc/pcmcia/wireless.opts}}. Remove the section marked "SECTION TO REMOVE"
at the beginning of the file and replace it with this:

<pre>
*,*,*,*)
ESSID="<the network name>"
KEY="<the key>"
MODE="Managed"
WPA="y"
;;
</pre>

Configure the network settings in {{path|/etc/pcmcia/network.opts}}. It's easiest if there is a DHCP server on the network, then the only change necessary is to ensure that

<pre>
DHCP="y"
</pre>

<tt>dhcpcd</tt> will clobber {{path|/etc/ntp.conf}} if you don't tell it not
to. Edit {{path|/etc/rc.d/rc.inet1}} and {{path|/etc/pcmcia/network}} and add
<tt>-N</tt> to every invocation of {{path|/sbin/dhcpcd}}. <tt>dhcpcd</tt> restores
the original {{path|/etc/ntp.conf}} when it exits, so kill any running <tt>dhcpcd</tt>
process before editing {{path|/etc/ntp.conf}}.

==Setting the clock==

NTP configuration is optional but it's nice to have the clock tell the right time, particularly
if there are NFS mounts.

The <tt>ntpd</tt> (version 4.2.0) supplied with Slackware 10.1 is a big program that
will hog more than 3MB of memory, so [http://chrony.sunsite.dk/ chronyd] is probably a better choice for the PC110. <tt>chronyd</tt> also measures the drift of
the hardware clock, so can make a better estimate of the time immediately following a reboot.

Create {{path|/etc/chrony.conf}} containing this:

<pre>
driftfile /etc/chrony.drift
rtcfile /etc/chrony.rtc
rtconutc
keyfile /etc/chrony.keys
commandkey 0

local stratum 10

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org
server ch.pool.ntp.org
server uk.pool.ntp.org

deny all
allow 127.0.0.1
</pre>

{{HINT|Choose NTP servers located fairly close by geographically, if possible. This particular choice of time servers is appropriate for a computer somewhere in Europe.}}

{{HINT|Set the time in the BIOS to UTC, or remove the line "rtconutc" from the configuration file. Keeping the time in the BIOS as UTC allows <tt>chronyd</tt> to keep track of daylight saving time correctly, but has the disadvantage that the time displayed on the front of the PC110 will be UTC not the local time.}}

Launch <tt>chronyd</tt> from {{path|/etc/rc.d/rc.local}}:

Create {{path|/etc/rc.d/rc.local}}, <tt>chmod 755</tt>, if it doesn't already exist.
Add
<pre>
echo "Starting NTP daemon: /usr/sbin/chronyd"
/usr/sbin/chronyd
</pre>

to start NTP when the {{PC110}} boots.

==Keyboard map==

Create {{path|/etc/rc.d/rc.keymap}} containing this:
<pre>
#!/bin/sh
# Load the keyboard map. More maps are in /usr/share/kbd/keymaps.
if [ -x /usr/bin/loadkeys ]; then
/usr/bin/loadkeys pc110.map
fi
</pre>
and <tt>chmod 755</tt>.

It'll be called from {{path|/etc/rc.d/rc.M}} when the system boots.

==Sound==

==Serial ports==

==Miscellaneous==

Prevent <tt>syslogd</tt> from filling up the log with
<pre>
Mar 12 08:40:33 carrot -- MARK --
Mar 12 09:00:36 carrot -- MARK --
Mar 12 09:20:41 carrot -- MARK --

messages (and, more importantly, waking up the disk all the time and draining the battery
without good reason) by editing {{path|/etc/rc.d/rc.syslog}}: add <tt>-m 0</tt> to the
invocation:
<pre>
echo -n "/usr/sbin/syslogd -m 0 "
/usr/sbin/syslogd -m 0
</pre>



{{path|/etc/rc.d/rc.modules}} is mostly comment; it only loads two modules as installed --
agpgart and ide-scsi. Neither are useful on the {{PC110}}, so comment both of them out to avoid a
couple of error messages at boot time.

|style="vertical-align:top" |This page is meant as a collection of information on how to save memory to make Linux work reasonable on older system with limited amount of RAM.

Most distributions nowadays don't take much care about it anymore, so there are a lot of things you can do to save memory. To get a smoothly working linux environment on a low memory machine you will need to conciously choose a lot of aspects of your system, most importantly the graphical environment, desktop environment and applications. This page provides detailed information about these various optimization possibilities.
|}

==Alternative graphical environments==
{{Todo|...}}

==Streamlining the desktop environment==
The common Desktop environments GNOME and KDE are, in their modern state, focused more on features, integration, and beauty rather than on resource saving. Understandable, but running Linux on an older ThinkPad with limited RAM requires conscious and sensitive resource usage more than anything else. The good thing about Linux is that a lot of things stay adjustable and customizable. So lets see what we can do about desktops.

One of the most important things is to decide for one graphical widget library and stick with that when you are choosing your desktop environment and applications. Having several toolkits in use means more libraries being loaded and hence more memory being used by those. Possibilities are:
* [http://www.fltk.org/ FLTK]
* [http://www.fox-toolkit.org/ FOX toolkit]
* [http://www.gnustep.org GNUstep toolkit]
* [http://www.gtk.org/ GTK] <tt>(not recommended, use GTK 2 if possible)</tt>
* [http://www.gtk.org/ GTK 2]
* [http://www.lesstif.org/ Lesstif] / [http://www.openmotif.org/ OpenMotif]
* [http://www.trolltech.com/products/qt/index.html QT]
* [http://www.windowmaker.org/development-wings.html WINGs] <tt>(kind of a lightweight GNUstep toolkit, provided by the WindowMaker developers)</tt>
* [http://www.x.org/ X Toolkit]

Of those, at current state, there are enough applications for the X Toolkit, GTK, GTK 2 and QT to provide you with a solution for every task you should want.

===GNOME===
It's like with humans, the worst feature is in most cases also the best one. For GNOME it is probably the many little parts it consists of. Makes it hard to install, but enables one to customize the installation. So, the first thing you should do to streamline GNOME is not to launch it. Sound stupid? Well, lets have a look.

GNOME is basically a set of libraries built around the GTK+ libs and extending its functionality. Add some nice little applications, a session manager, a panel, beautiful icons, and some other stuff and you have GNOME as you know it. Reversing those additions is what you can do to use GNOME applications on a machine that this desktop environment would normally take your nerves on.

The GNOME panel, the session manager, the desktop manager and the window manager are all parts of GNOME that eat a lot of memory for something that others can do in a maybe little less beautiful but much more resource saving way.
So first off configure your login manager not to launch gnome-session at login. If you are using GDM this is quite straight forward, you just need to add a different session script, launching your favorite window manager. See the list below and pick one, lets say i.e. WindowMaker. WindowMaker uses a desktop menu, a dock and a notification area to provide you with an organized way of launching applications and iconfying running ones. So we don't need a panel anymore. Also, think if you really need icons on your desktop. If you do, think about using something like ROX filer instead of nautilus for that. In any case, tell nautilus not to manage the desktop by default by unchecking the according setting within gconf-editor. To keep GNOME applications happy we would need to have gconf and gnome-settings-manager running at every session start. One way to do this is to either include them in your new session script. They both need to be running to make GNOME applications realize their settings properly.

===KDE===
{{Todo|...}}

===Alternative Desktop Environments===
First of all, it is important to notice that GNOME and KDE are not the only Desktop Environments around.
Other complete (featuring most of: window management, session management, desktop management, file management and panel) desktop environments are:
*[http://xfce.org/ XFCE] <tt>uses GTK 2</tt>
*[http://ede.sourceforge.net Equinox Desktop Environment] <tt>uses eFLTK, a modified version of FLTK</tt>
*[http://www.nongnu.org/antiright/ AntiRight Desktop Environment] <tt>uses LessTif / OpenMotif</tt>
*[http://foxdesktop.sourceforge.net/ FOX Desktop Environment] <tt>uses FOX Toolkit</tt>
*[http://www.gnustep.org/ GNUstep] <tt>provides it's own toolkit</tt>

But also, some Window Managers exceed the task of managing windows towards providing a functional workbench. See below for a list.

===Building your own Desktop===

====Window Manager====
If you want to build your own customized desktop, a good start is choosing the window manager of your liking.

Here's a list of some of them:
*including basic Desktop Environment functionality
**the [[Wikipedia:NextStep|NextStep]] alike ones
***[http://www.windowmaker.org/ WindowMaker] <tt>(probably the most widespread NextStep like WM)</tt>
***[http://www.afterstep.org/ AfterStep] <tt>(another one of those)</tt>
**the Blackbox-like ones
***[http://blackboxwm.sourceforge.net/ BlackBox]
***[http://fluxbox.sourceforge.net/ FluxBox] <tt>(tabbed windows, lighweight)</tt>
**others
***[http://www.icewm.org/ IceWM] <tt>(lightweight, widespread)</tt>
***[http://enlightenment.sourceforge.net/ Enlightenment] <tt>(lots of features and eye candy)</tt>
***[http://www.pekwm.org PekWM] <tt>(kind of a one man show, but feature rich and extremely customizable)</tt>
*pure WindowManagers
**[http://golem.sourceforge.net/ Golem]
**[http://home.earthlink.net/~lab1701/larswm/ LarsWM] <tt>(unique tiling Window Manager)</tt>
**[http://www.nongnu.org/ratpoison/ ratpoison] <tt>(modeled after gnu screen)</tt>
**[http://fvwm.org/ fvwm] <tt>(small but powerful)</tt>
**[http://www.jfc.org.uk/software/lwm.html lwm] <tt>(very small, and fast)</tt>
**[http://www.all-day-breakfast.com/wm2/ wm2] <tt>really small Window Manager</tt>
**[http://www.all-day-breakfast.com/wmx/ wmx] <tt>slightly more featureful version of wm2</tt>

====Taskbar/Panel====
Another thing that especially users coming to Linux from the Windows world would probably like is a Panel or Taskbar.

Here's a collection of independant low resource panels:
*[http://www.chatjunkies.org/fspanel/ F***ing Small Panel] <tt>(doesn't use any toolkit)</tt>
*[http://freshmeat.net/projects/hpanel/ HPanel] <tt>(doesn't use any toolkit)</tt>
*[http://fbpanel.sourceforge.net/ fbpanel] <tt>(depends on GTK 2)</tt>
*[http://jodrell.net/projects/perlpanel Perl Panel] <tt>(depends on GTK 2, gnomevfs, perl)</tt>
*[http://www.gkrellm.net/ GKrellM] <tt>(depends on GTK 2, flexible plugin based skinable vertical panel)</tt>

====Desktop Pinboard====
Then, the next thing you might be looking for is how to get icons onto your desktop. Usually this is done by the file manager who displays the content of a special directory as icons on the desktop. See the File Manager section to follow this approach.

However, you might decide for a really lightwight file manager which doesn't offer this feature. In that case all hope is not lost, for there are also special programs specialized in desktop icon management. Such are:
* [http://idesk.sourceforge.net/ iDesk] <tt>(recent versions need imlib2 only)</tt>

====File Manager====
File Managers are the fourth really important compontent of a desktop environment. There are plenty out their ranging from resource hugs to really lightweight and slim ones.

File Managers come with three distinct general user interface approaches: the two pane gui, the spacial and the browser gui. The browser gui is the one the Windows Explorer starting from Windows 2000 uses as well as earlier versions of Nautilus. The spacial view is the one known from Windows 95 and more recent versions of Nautilus. The two pane view is know to many from Norten Commander, Directory Opus or your favorite FTP client.

The following list provides an overview.

** [http://orbis.sourceforge.net/ Orbis] <tt>(3D gui)</tt>

==Choosing applications==
===Web Browser===
This is highly dependend on the way you use your browser, it's often worth it to try out all and just track general
memory usage. Remember that <tt>top</tt> and <tt>ps</tt> don't report correct memory usage, track totals only.

====Firefox====
Firefox is graphical web browser. One can install features like AdBlock and FlashClicktoplay which will decrease memory and
processor usage by hiding Flash and Java -adverts.

====Opera====
Opera is graphical web browser. You can easily enable/disable plug-ins and java (press F12) and decrease memory usage.
Opera uses QT as toolkit, so you may shave off some Mbytes off memory usage by using dynamically linked version if you use KDE.

====Konqueror====
Konqueror is graphical web browser. It's integrated with KDE and has several advanced features (esp. ca. KDE 3.5).
You may save some megabytes by using it instead of other browsers when using KDE.
It's not necessarily heavy even when used without running KDE.

====Dillo====
Dillo is minimalistic and very small graphical web browser.

====Elinks/Lynx====
elinks/lynx are both text mode web browsers. <tt>elinks</tt> handles tables and formatting much nicer than <tt>lynx</tt>.
Both go very easy on memory footprint.

==Disabling unneeded system deamons==
Another thing you can do to improve performance is to get rid of unneaded system daemons launched from your init scripts. Disable them by using the according configuration interface of your distro or by deleting links in the according runlevel directories (usually in <code>/etc/rc.d/</code>).

Daemons you usually don't need:
* httpd <tt>(Apache web server)</tt>
* mysqld <tt>(MySQL database server)</tt>
* smbd <tt>(SMB windows filesharing server)</tt>
* pppd <tt>(PPP server for connections through modems and serial lines)</tt>

==Adjusting filesystems==
You can also try to optimize memory usage by making sure that you have as little as possible of your filesystem residing in RAM. To do this make sure that the following mount points are set to reside on your harddisk in {{path|/etc/fstab}}.
* /dev (not possible if you use udev)
* /tmp

Also make sure that you mount filesystems with extensive usage with noatime parameter (mount -o remount,ro /...), which disabled access time writes every time you access some file. Note that many incremental backups needs atime to work, such backups will then behave like full backup everytime. This depends on backup systems.

==Other tips==
===Disk space===
When using Debian/Ubuntu/other derivative, use <tt>aptitude</tt> as package manager, and use it as soon as possible. Use it and only it to install and remove packages.

One of it's most usefull features is that it tracks packages you install and marks packages installed via dependency as such, so when you remove a package that is no longer used, or package updates and doesn't use a library anymore, that dependency will get uninstalled.

You can mark packages installed as automatically installed by hitting 'M' (uppercase m), it will be marked for deinstallation if it's not longer required.

You could also install localepurge wich will remove all unneded locales and localized manpages for packages you install.

How to save memory

|style="vertical-align:top" |This page is meant as a collection of information on how to save memory to make Linux work reasonable on older system with limited amount of RAM.

Most distributions nowadays don't take much care about it anymore, so there are a lot of things you can do to save memory. To get a smoothly working linux environment on a low memory machine you will need to conciously choose a lot of aspects of your system, most importantly the graphical environment, desktop environment and applications. This page provides detailed information about these various optimization possibilities.
|}

==Alternative graphical environments==
{{Todo|...}}

==Streamlining the desktop environment==
The common Desktop environments GNOME and KDE are, in their modern state, focused more on features, integration, and beauty rather than on resource saving. Understandable, but running Linux on an older ThinkPad with limited RAM requires conscious and sensitive resource usage more than anything else. The good thing about Linux is that a lot of things stay adjustable and customizable. So lets see what we can do about desktops.

One of the most important things is to decide for one graphical widget library and stick with that when you are choosing your desktop environment and applications. Having several toolkits in use means more libraries being loaded and hence more memory being used by those. Possibilities are:
* [http://www.fltk.org/ FLTK]
* [http://www.fox-toolkit.org/ FOX toolkit]
* [http://www.gnustep.org GNUstep toolkit]
* [http://www.gtk.org/ GTK] <tt>(not recommended, use GTK 2 if possible)</tt>
* [http://www.gtk.org/ GTK 2]
* [http://www.lesstif.org/ Lesstif] / [http://www.openmotif.org/ OpenMotif]
* [http://www.trolltech.com/products/qt/index.html QT]
* [http://www.windowmaker.org/development-wings.html WINGs] <tt>(kind of a lightweight GNUstep toolkit, provided by the WindowMaker developers)</tt>
* [http://www.x.org/ X Toolkit]

Of those, at current state, there are enough applications for the X Toolkit, GTK, GTK 2 and QT to provide you with a solution for every task you should want.

===GNOME===
It's like with humans, the worst feature is in most cases also the best one. For GNOME it is probably the many little parts it consists of. Makes it hard to install, but enables one to customize the installation. So, the first thing you should do to streamline GNOME is not to launch it. Sound stupid? Well, lets have a look.

GNOME is basically a set of libraries built around the GTK+ libs and extending its functionality. Add some nice little applications, a session manager, a panel, beautiful icons, and some other stuff and you have GNOME as you know it. Reversing those additions is what you can do to use GNOME applications on a machine that this desktop environment would normally take your nerves on.

The GNOME panel, the session manager, the desktop manager and the window manager are all parts of GNOME that eat a lot of memory for something that others can do in a maybe little less beautiful but much more resource saving way.
So first off configure your login manager not to launch gnome-session at login. If you are using GDM this is quite straight forward, you just need to add a different session script, launching your favorite window manager. See the list below and pick one, lets say i.e. WindowMaker. WindowMaker uses a desktop menu, a dock and a notification area to provide you with an organized way of launching applications and iconfying running ones. So we don't need a panel anymore. Also, think if you really need icons on your desktop. If you do, think about using something like ROX filer instead of nautilus for that. In any case, tell nautilus not to manage the desktop by default by unchecking the according setting within gconf-editor. To keep GNOME applications happy we would need to have gconf and gnome-settings-manager running at every session start. One way to do this is to either include them in your new session script. They both need to be running to make GNOME applications realize their settings properly.

===KDE===
{{Todo|...}}

===Alternative Desktop Environments===
First of all, it is important to notice that GNOME and KDE are not the only Desktop Environments around.
Other complete (featuring most of: window management, session management, desktop management, file management and panel) desktop environments are:
*[http://xfce.org/ XFCE] <tt>uses GTK 2</tt>
*[http://ede.sourceforge.net Equinox Desktop Environment] <tt>uses eFLTK, a modified version of FLTK</tt>
*[http://www.nongnu.org/antiright/ AntiRight Desktop Environment] <tt>uses LessTif / OpenMotif</tt>
*[http://foxdesktop.sourceforge.net/ FOX Desktop Environment] <tt>uses FOX Toolkit</tt>
*[http://www.gnustep.org/ GNUstep] <tt>provides it's own toolkit</tt>

But also, some Window Managers exceed the task of managing windows towards providing a functional workbench. See below for a list.

===Building your own Desktop===

====Window Manager====
If you want to build your own customized desktop, a good start is choosing the window manager of your liking.

Here's a list of some of them:
*including basic Desktop Environment functionality
**the [[Wikipedia:NextStep|NextStep]] alike ones
***[http://www.windowmaker.org/ WindowMaker] <tt>(probably the most widespread NextStep like WM)</tt>
***[http://www.afterstep.org/ AfterStep] <tt>(another one of those)</tt>
**the Blackbox-like ones
***[http://blackboxwm.sourceforge.net/ BlackBox]
***[http://fluxbox.sourceforge.net/ FluxBox] <tt>(tabbed windows, lighweight)</tt>
**others
***[http://www.icewm.org/ IceWM] <tt>(lightweight, widespread)</tt>
***[http://enlightenment.sourceforge.net/ Enlightenment] <tt>(lots of features and eye candy)</tt>
***[http://www.pekwm.org PekWM] <tt>(kind of a one man show, but feature rich and extremely customizable)</tt>
*pure WindowManagers
**[http://golem.sourceforge.net/ Golem]
**[http://home.earthlink.net/~lab1701/larswm/ LarsWM] <tt>(unique tiling Window Manager)</tt>
**[http://www.nongnu.org/ratpoison/ ratpoison] <tt>(modeled after gnu screen)</tt>
**[http://fvwm.org/ fvwm] <tt>(small but powerful)</tt>
**[http://www.jfc.org.uk/software/lwm.html Lightweight Window Manager] <tt>(very small, and fast)</tt>
**[http://www.all-day-breakfast.com/wm2/ wm2] <tt>really small Window Manager</tt>
**[http://www.all-day-breakfast.com/wmx/ wmx] <tt>slightly more featureful version of wm2</tt>

====Taskbar/Panel====
Another thing that especially users coming to Linux from the Windows world would probably like is a Panel or Taskbar.

Here's a collection of independant low resource panels:
*[http://www.chatjunkies.org/fspanel/ F***ing Small Panel] <tt>(doesn't use any toolkit)</tt>
*[http://freshmeat.net/projects/hpanel/ HPanel] <tt>(doesn't use any toolkit)</tt>
*[http://fbpanel.sourceforge.net/ fbpanel] <tt>(depends on GTK 2)</tt>
*[http://jodrell.net/projects/perlpanel Perl Panel] <tt>(depends on GTK 2, gnomevfs, perl)</tt>
*[http://www.gkrellm.net/ GKrellM] <tt>(depends on GTK 2, flexible plugin based skinable vertical panel)</tt>

====Desktop Pinboard====
Then, the next thing you might be looking for is how to get icons onto your desktop. Usually this is done by the file manager who displays the content of a special directory as icons on the desktop. See the File Manager section to follow this approach.

However, you might decide for a really lightwight file manager which doesn't offer this feature. In that case all hope is not lost, for there are also special programs specialized in desktop icon management. Such are:
* [http://idesk.sourceforge.net/ iDesk] <tt>(recent versions need imlib2 only)</tt>

====File Manager====
File Managers are the fourth really important compontent of a desktop environment. There are plenty out their ranging from resource hugs to really lightweight and slim ones.

File Managers come with three distinct general user interface approaches: the two pane gui, the spacial and the browser gui. The browser gui is the one the Windows Explorer starting from Windows 2000 uses as well as earlier versions of Nautilus. The spacial view is the one known from Windows 95 and more recent versions of Nautilus. The two pane view is know to many from Norten Commander, Directory Opus or your favorite FTP client.

The following list provides an overview.
*FLTK
** [http://www.oksid.ch/flfm/ Fast Light File Manager] <tt>(spacial gui)</tt>
* FOX toolkit

** [http://orbis.sourceforge.net/ Orbis] <tt>(3D gui)</tt>

==Choosing applications==
===Web Browser===
This is highly dependend on the way you use your browser, it's often worth it to try out all and just track general
memory usage. Remember that <tt>top</tt> and <tt>ps</tt> don't report correct memory usage, track totals only.

====Firefox====
Firefox is graphical web browser. One can install features like AdBlock and FlashClicktoplay which will decrease memory and
processor usage by hiding Flash and Java -adverts.

====Opera====
Opera is graphical web browser. You can easily enable/disable plug-ins and java (press F12) and decrease memory usage.

You may save some megabytes by using it instead of other browsers when using KDE.
It's not necessarily heavy even when used without running KDE.

|style="vertical-align:top" |
The following tables headings shell designate the following meanings...

* APM
** Blank = ability to turn off the LCD while using APM
** Sleep = ability to do a suspend-to-ram using APM
** Hibernate = ability to perform a suspend-to-disk via the BIOS
** Battery = ability to get statistics on remaining battery life from the APM subsystem
*ACPI
** Blank = ability to turn off the LCD while using ACPI
** Sleep = ability to do a suspend-to-ram using ACPI
** Hibernate = ability to perform a suspend-to-disk using ACPI
** Battery = ability to get statistics on remaining battery life from the ACPI subsystem

The fields should be filled with one of the following:
* ? = unknown / untested
* yes = working (with or without extra configuration effort)
* no = not working (because kernel support isn't there yet)
* part = partially working (unsolvable trouble on resume or something like that)
* N/A = not supported by the hardware
* ACPI-Hibernate can additionally have one of these:
** sus - hibernation works using the old in-kernel (2.6) [[swsusp]]
** sus2 - hibernation works using [[Software Suspend 2]]

The "4MB EPROM" is an internal 4MB CompactFlash device, that normally appears as /dev/hda. "With removable media" that hdparm claims here is a lie, unless you're handy with a very small screwdriver and soldering iron.

<pre>
ed@carrot:~$ sudo /usr/sbin/hdparm -I /dev/hda

/dev/hda:
