Problem with unauthorized MiniPCI network card

2007-07-11T15:03:12Z

Dustymugs: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer method than modifying the BIOS is modifying the PCI-ID of the wlan card. The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards.
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

<code>
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(void)
{
int fd;
unsigned char data;

fd = open("/dev/nvram", O_RDWR);
if (fd==-1) {
printf("Opening /dev/nvram failed\n");
return 1;
}
printf("Disabling WiFi whitelist check.\n");

/* BIG INFORMATIONAL WARNING */
/* The linux nvram driver doesn't give access to the first 14 bytes of
the CMOS. As a result, we seek to 0x5c rather than 0x6a. If you're
implementing this under another OS, then you'll have to go to whichever
address is appropriate for your access method */

lseek(fd, 0x5c, SEEK_SET);
read(fd, &data, 1);
printf("CMOS address 0x5c: %02x->", data);
data |= 0x80;
printf("%02x\n", data);
lseek(fd, 0x5c, SEEK_SET);
if (write(fd, &data, 1)<0) {
printf("Unable to write to /dev/nvram - hack failed\n");
close(fd);
return 2;
}
close(fd);
printf("Done.\n");
return 0;
}

</code>
{{NOTE|On the R32, T43, X60 and probably others, the BIOS hacks and the "no-1802" utility don't work.}}

==Successful BIOS Modifications==
{{WARN|This table is meant to give users an idea of what models have been successfully modified and how. As stated before, it is dangerous to mess with your BIOS, you can easily make your machine unbootable. Please proceed with caution!}}

The following table contains information about ThinkPad models that have been successfully modified to run an unauthorized Mini PCI card. {{footnote|4}}

Problem with unauthorized MiniPCI network card

2007-05-26T16:16:06Z

Dustymugs: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer method than modifying the BIOS is modifying the PCI-ID of the wlan card. The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards.
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

<code>
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(void)
{
int fd;
unsigned char data;

fd = open("/dev/nvram", O_RDWR);
if (fd==-1) {
printf("Opening /dev/nvram failed\n");
return 1;
}
printf("Disabling WiFi whitelist check.\n");

/* BIG INFORMATIONAL WARNING */
/* The linux nvram driver doesn't give access to the first 14 bytes of
the CMOS. As a result, we seek to 0x5c rather than 0x6a. If you're
implementing this under another OS, then you'll have to go to whichever
address is appropriate for your access method */

lseek(fd, 0x5c, SEEK_SET);
read(fd, &data, 1);
printf("CMOS address 0x5c: %02x->", data);
data |= 0x80;
printf("%02x\n", data);
lseek(fd, 0x5c, SEEK_SET);
if (write(fd, &data, 1)<0) {
printf("Unable to write to /dev/nvram - hack failed\n");
close(fd);
return 2;
}
close(fd);
printf("Done.\n");
return 0;
}

</code>
{{NOTE|On the R32, T43, X60 and probably others, the BIOS hacks and the "no-1802" utility don't work.}}

==Successful BIOS Modifications==
{{WARN|This table is meant to give users an idea of what models have been successfully modified and how. As stated before, it is dangerous to mess with your BIOS, you can easily make your machine unbootable. Please proceed with caution!}}

The following table contains information about ThinkPad models that have been successfully modified to run an unauthorized Mini PCI card. {{footnote|4}}

Problem with unauthorized MiniPCI network card

2007-05-26T16:02:20Z

Dustymugs: /* Successful BIOS Modifications */

==Problem Description==
Although the MiniPCI slot is an industry standard and can accept any MiniPCI adapter, the IBM BIOS is set to only allow you to boot with an 'authorized' adapter installed. Attempts to install an unsupported card will result in the following message:

1802: Unauthorized network card is plugged in - Power off and remove the miniPCI network card.

This is because the card's sub-vendor PCI-ID (which can be seen using ''lspci -v'') are checked against a [[Wikipedia:Whitelist|whitelist]] in the BIOS. IBM's reasoning for this is that the combination of MiniPCI card and the integrated antenna in the ThinkPad needs to be certified by the US FCC (Federal Communications Commission).{{footnote|1}} or similar agencies in other countries.

==Affected Models==
All machines with integrated WiFi, or machines with WiFi added

==Affected Operating Systems==
All - problem is in the BIOS

==Status==
* Workarounds exist for most affected models.

==Solutions==
It may be possible to use the computer with the unauthorized card deactivated (but not removed). Press {{key|F1}} to enter the BIOS and deactivate the WLAN card, then attempt to boot with the card disabled. This does not make the wireless card work, but it may allow you to boot the computer normally.

{{NOTE|Any of the following solutions should suffice to make the wireless card useable. You only need to perform one of them.}}

* You may can modify the BIOS whitelist to include the PCI-ID of the card you wish to use. The complete instructions for this procedure are [http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html here].
{{WARN|It is dangerous to mess with your BIOS, you can easily make your machine unbootable, proceed with caution!}}

* A safer method than modifying the BIOS is modifying the PCI-ID of the wlan card. The instructions are [http://www.dagarlas.org/stuff/computing/article0001.php here]. This page is for Atheros-based cards and HP notebooks, but it applies to Thinkpads as well. It also has links on how to edit the PCI-ID on Intel Pro Wireless cards.
{{NOTE|Modifying your PCI-ID will require either a laptop without a BIOS lock or a PCI adapter for your desktop. Also, this procedure can render your card useless, but that's better than bricking your laptop.}}

* You can use the [[Problem with error 01C9 - More than one Ethernet devices | no-1802 and no-01C9 Linux Live CD]] without applying the no-01C9 patch. It is very convenient to use and based on the C code below.

* You can use the DOS [http://jcnp.pku.edu.cn/~shadow/1802/no-1802.com no-1802] utility, written by Tisheng Chen.{{footnote|2}} It will set a certain bit in the CMOS memory which disables the whitelist check, but it has been reported not to work on the latest machines, such as the T43

* You can compile and run (as root) the following C-code, which was written by Matthew Garrett. It was based on the code written by Vojtech Pavlik, which in turn was based on the assembly used in the no-1802 program. {{footnote|3}}

<code>
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <sys/stat.h>
#include <fcntl.h>

int main(void)
{
int fd;
unsigned char data;

fd = open("/dev/nvram", O_RDWR);
if (fd==-1) {
printf("Opening /dev/nvram failed\n");
return 1;
}
printf("Disabling WiFi whitelist check.\n");

/* BIG INFORMATIONAL WARNING */
/* The linux nvram driver doesn't give access to the first 14 bytes of
the CMOS. As a result, we seek to 0x5c rather than 0x6a. If you're
implementing this under another OS, then you'll have to go to whichever
address is appropriate for your access method */

lseek(fd, 0x5c, SEEK_SET);
read(fd, &data, 1);
printf("CMOS address 0x5c: %02x->", data);
data |= 0x80;
printf("%02x\n", data);
lseek(fd, 0x5c, SEEK_SET);
if (write(fd, &data, 1)<0) {
printf("Unable to write to /dev/nvram - hack failed\n");
close(fd);
return 2;
}
close(fd);
printf("Done.\n");
return 0;
}

</code>
{{NOTE|On the R32, T43, X60 and probably others, the BIOS hacks and the "no-1802" utility don't work.}}

==Successful BIOS Modifications==
{{WARN|This table is meant to give users an idea of what models have been successfully modified and how. As stated before, it is dangerous to mess with your BIOS, you can easily make your machine unbootable. Please proceed with caution!}}

Additional options for the radeon driver

2007-05-25T13:52:59Z

Dustymugs: /* AGP Fast Writes */

Options for the [[radeon]] driver are documented on the radeon(4x) man page.

==External Monitors==

First of all, suppose you want to plug in your laptop into a projector occasionally, but you
don't want to restart X when you do so.
The easiest thing is to not use any of the CRT2 options and use

Option "MonitorLayout" "LVDS,NONE"

The vga port will carry the same signal as the laptop display
(at least on my T42p). If the projector does not support the resolution, you can change it using xrandr.

===Using Xinerama===

You can use '''MergedFB''' to provide dualhead '''Xinerama'''-like setups. MergedFB's pseudo-Xinerama is not Xorg server's Xinerama. You don't have to enable Xorg server's Xinerama to use MergedFB's pseudo-Xinerama. However, applications compiled with Xinerama support (Gentoo users USE="xinerama") can interpret pseudo-Xinerama hints, for example, to maximize to a single monitor instead of spanning two monitors.

The following (partial) '''Xorg''' config will make the Radeon card use '''1024x768''' on the internal lcd display and '''1280x1024''' on the external ('''Note''': only one screen/monitor section is needed (it controls the setup of the internal monitor) even though we have two displays):
'''N.B.:''' Modes used in the ''MetaModes'' also have to be present in the ''screen'' modes section.

Section "Device"
Identifier "ATI"
Driver "radeon"
'''# accelration'''
Option "AGPMode" "4"
Option "EnablePageFlip" "on"
Option "RenderAccel" "on"
'''# enable (partial) PowerPlay features'''
Option "DynamicClocks" "on"
'''# use bios hot keys on thinkpad (aka fn+f7)'''
Option "BIOSHotkeys" "on"
'''# enable radeon specific xinerama'''
Option "MergedFB" "true"
Option "CRT2Position" "RightOf"
Option "CRT2Hsync" "50-75"
Option "CRT2VRefresh" "30-82"
Option "MetaModes" "1024x768-1280x1024"
Option "MergedNonRectangular" "true"
BusID "PCI:1:0:0"
EndSection
Section "Monitor"

Modes "1024x768"
EndSubSection

Note: The '''CRT2''' directives always applies for the external monitore regardless of type (LCD, CRT...). The option '''MergedNonRectangular''' is needed to force the screens into two different sizes.

===External Monitors and Docking Stations/Port Replicators===
I seems that '''Xorg''' incorectly discovers the external displays when connected to a docking station/port replicator - the only solution to this problem (at least that I know of) is to start the laptop (and boot all the way into X) prior to inserting it in the dock.

It also happens that if you are attempting to use the mergedFB trick to
do dual head with out a docking station, you have to start X on the laptop
LCD first, then plug a monitor into the VGA port. If the external monitor
is already plugged in, the internal LCD will be blank.

I found that if I add '''Option "MonitorLayout" "LVDS, CRT"''' to my xorg.conf file - I don't have the 'blank' LCD panel problem when I plug the external monitor in before powering up. (Radeon 9600 M10 [RV350] with xorg 7.0.0). However - if you want anything other than 'Clone' mode of MergeFB, then you also have to make sure your "Modes" line in the "Screen" section contains the both modes defined in your MetaModes option.
<pre>
Option "MonitorLayout" "LVDS, CRT"
Option "MetaModes" "1024x768-1280x1024"
....
SubSection "Display"
Depth 24
Modes "1024x768" "1280x1024"
</pre>
This also resulted in my Notebook having a Virtual screen size of "2304x1024" when the external monitor is connected - but only 1024x768 when it's not connected. Until I did this - even with the external monitor disconnected - the virtual screen size was "2304x1024" and windows would open where I couldn't get to them.

===External Monitors and FireGL Boards with x.org 7===
x.org release 7, the modular release, broke mergedfb mode with FireGL boards (t4xp systems). Dual screen displays hard locked the machine in certain cases. This is fixed in x.org cvs. Fedora Core 5 (and possibly other distros using x.org 7) can get a new version of radeon_drv.so [http://www.marcuswatkins.net/firegl_xorg7_fedora.html here].

==AGP speed==

By default, the open source radeon driver forces 1x AGP speed. Quote from the developers:

tuning to the highest speed possible has caused hangs on some boxes, with no
discernable pattern, so we default to 'slow but safe' whilst giving the option
to go fast if the user wants to try it.

Higher speeds can be enabled by adding '''Option "AGPMode" "X"''' (where X is a number) in the '''Device''' section in {{path|/etc/X11/xorg.conf}}.

Section "Device"
Identifier "Videocard0"
Driver "radeon"
VendorName "IBM Thinkpad"
BoardName "ATIdd Mobility FireGL 7800"
'''Option "AGPMode" "4"'''
EndSection

With this option enabled (set to 4x speed), the X11 server should print ({{path|/var/log/Xorg.0.log}}):

(**) RADEON(0): Option "AGPMode" "4"
(**) RADEON(0): Using AGP 4x mode

==AGP Fast Writes==

By default, the open source radeon driver disables AGP Fast Writes. Fast Writes can be enabled by adding '''Option "AGPFastWrite" "yes"''' in the '''Device''' section in {{path|/etc/X11/xorg.conf}}.

Section "Device"
Identifier "Videocard0"
Driver "radeon"
VendorName "IBM Thinkpad"
BoardName "ATI Mobility FireGL 7800"
'''Option "AGPFastWrite" "yes"'''
EndSection

{{NOTE|With this one X hangs on startup (black screen) on my ThinkPad T42 (helios42)}}
{{NOTE|The same problem as above (X hangs on startup (black screen)) has been experienced on a ThinkPad T41p}}

==Dynamic Clock scaling==

Please see:

*[[How to make use of Graphics Chips Power Management features]] <tt>(save even more battery power)</tt>
*[https://bugs.freedesktop.org/show_bug.cgi?id=2187 Xorg bug] <tt>DynamicClocks may hang your machine</tt>

==Color Tiling==

ColorTiling is supposed to be enabled by default. But, it looks like setting it explicitely to "on" increases the FPS in glxgears.

Option "ColorTiling" "on"

==Acceleration Architecture==

By default, the XAA architecture is used. EXA is newer and supposed to have better performance. It looks like it reduces the FPS in glxgears (maybe because it disables Page Flip) but makes the Composite extension be fast.

Option "AccelMethod" "EXA"

==Page Flip==

Page Flip increases performance but is not always supported. It will be disabled if the EXA architecture is used.

Option "EnablePageFlip" "on"

==Video overlay==

When the video overlay is used (e.g., by most video players) in dual-screen configuration, the content will be shown only on one head (LCD or CRT) and the other will display a blank rectangle. To control which head displays the video, use the following:

Option "OverlayOnCRTC2" "on"

Note : You may want to have the video overlay on ''both'' Screens. Simply add the following 2 lines :

Option "OverlayOnCRTC1" "on"
Option "OverlayOnCRTC2" "on"

To switch on the fly, use these commands:

:{{cmd|xvattr -a XV_SWITCHCRT -v 0|}}   (LCD)
:{{cmd|xvattr -a XV_SWITCHCRT -v 1|}}   (CRT)

{{HINT|You can configure [[acpid]] to execute these commands automatically when the lid is opened or closed.}}

Problem with ati driver in xorg 6.9.x

2007-05-23T03:46:25Z

Dustymugs: /* Affected Models */

Information about the problem of system lockups with the ATI driver.

==Problem description==

A few minutes after starting X windows the system locks up hard.

==Affected Models==

*ThinkPad {{T42}}
*ThinkPad {{T41p}}
*other ThinkPads with a FireGL chipset and possibly other ATI chipsets

==Affected Operating Systems==

*Xorg 6.9.x

==Status==

The problem has been fixed in 7.0. However, some Linux distributions still release 6.9.x as their current version.

==Solutions==

The easiest solution is to switch to the "vesa" driver in xorg.conf.

You can also downgrade to 6.9.x or upgrade to 7.0. Debian users can get 6.9.x packages from [http://snapshot.debian.net].
