==== Installing Fedora Core 5 ====
* Aside from the following PCM issue, the configuration challenges are the routine issues of deciding on your partitioning and deciding which packages to include.
* After the first reboot, the installation process asks your choice for default PCM device. The two options are: Intel ICH - Intel ICH6 / Intel ICH - IEC958.

I have no idea which to choose, and don't know if the choice is one that can easily be changed later.
There is no obvious external digital output, so I choose the first and hope for the best.

* After the initial install, in order to get the system up to date, you will have to TWICE as root issue the command:
{{cmdroot|yum update}}
and then wait a long time for each update to complete, as there may be around 100 packages updated each time.
* see [[1400x1050 on Intel 915GM]]. Download and install 915resolution and add to /etc/rc.local the line: 915resolution 3c 1400 1050
* Getting suspend and resume to work:
** Check BIOS setting: Power On; Press F1 to enter BIOS settings. Check that the value for Config -> Power -> "Allow suspend mode on legacy OS" is: Enabled. On my system, this BIOS option did not affect FC4; however FC5 would not resume properly if the setting was Disabled.
** To /boot/grub/grub.conf add to the relevant lines beginning "kernel" the following option: acpi_sleep=s3_bios
** To /usr/sbin/pm-suspend, following the line echo -n "mem" > /sys/power/state, add the line: 915resolution 3c 1400 1050

* Controlling cpuspeed: My preference is to edit /etc/cpuspeed.conf, commenting out -n and adding OPTS="$OPTS -s 0 -i 1 -r -p 45 50". My CPU use patterns are high spikes with low idles so this provides maximum responsiveness but generally keeps the CPU at (ambient temperature + 20 degrees Celsius).

==== Installing Fedora 7 ====
* To avoid problems when the computer is turned on with external monitor connected:
** BIOS setting: Configure Display: Startup on Internal LCD (not Both)

* To get the native 1400x1050 internal LCD resolution:
** Install 915resolution
** Edit /etc/sysconfig/915resolution to have the line
RESOLUTION="3c 1400 1050"
* To get the internal display to resume properly after suspend (instead of the ghostly glow)
** Make an executable file /etc/pm/config.d/r52.cfg with

#!/bin/sh
DISPLAY_QUIRK_S3_BIOS=true

RichardHughes: '''Please DO NOT do this'''. Please see the [http://people.freedesktop.org/~hughsient/quirk/index.html quirks pages] for a better fix

* Edit xorg.conf to enable different desktop on external 1280x1024 monitor: to Section "Screen", Identifier "Screen0", Subsection "Display" add
Virtual 2680 1050

* script to run when in X:

#!/bin/sh
xrandr --output VGA --right-of LVDS --off >/dev/null 2>&1 || :
xrandr -s 1400x1050 >/dev/null 2>&1 || :
if xrandr | grep "VGA connected"; then
xrandr --output VGA --right-of LVDS --auto
fi

* Internal Modem identified as Intel 82801FB/FBM/FR/FW/FRW (ICH6 family) AC'97 Modem Controller
