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:

# 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
    • (2006.04.20) If on resume the video is not restored, there may be video configuration issues. It is possible to get suspend working with DRI; I hope to soon provide a working dual head xorg.conf that allows resume from suspend. So, only if there is a problem, try the following: edit the file /etc/X11/xorg.conf, find the section "Module" and comment out the line that says load "DRI" by putting a hash mark # at the beginning of the line:

# load "DRI"

  • 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).
