1. Hardware Configuration

2. Install

Due to the Sata DVD Drive, CentOS 5.3 installer will not boot without adding the kernel option "pci=nomsi". Both 32 and 64 bits were tested. Also tested was CentOS 5.2 (32 bit) it never booted into the installer.

At the prompt when you boot from installer CD/DVD type:

linux pci=nomsi

3. Post Install

Once the install process is finished you are asked to reboot. When you reboot the boot process will hang with a kernel panic if you do not add "nomce" to the kernel line. This is a bit trickier then before.

  1. Once you see the blue sceen saying "Booting CentOS..." press the space bar.
  2. Now select the kernel line with your arrow keys and press "e" to edit this line.
  3. Add "nomce" (without the quotes) to the end of this line and hit enter.
  4. Press the "b" key to continue booting.

This will allow you to boot without the kernel panic. Once logged in switch user (su) to root and edit the "/boot/grub/grub.conf" file with nano or vi(m) to make the changes permanent. You will see the same kernel line you just changed on boot. Change that same line adding the same "nomce" to the end of that line.

4. Networking

On first boot there are no network cards detected or configured. The following will get you going on both wired and wireless.

You will need internet access from another computer to follow these steps. You will also need a CD/DVD writer (a blank disk) or a USB drive.

Download both drivers below at the same time and copy them to USB flash drive/hard drive or CD/DVD. Then follow all steps.

4.1. Wired Ethernet

Depending on if you are going with a 32 bit or 64 bit install you will need one of these drivers:

32 bit... http://www.elrepo.org/linux/elrepo/el5/i386/RPMS/kmod-forcedeth-0.62-1.25.1.el5.elrepo.i686.rpm

or 64 bit... http://www.elrepo.org/linux/elrepo/el5/x86_64/RPMS/kmod-forcedeth-0.62-1.25.1.el5.elrepo.x86_64.rpm

  1. Just download/copy the driver to your home folder.
  2. Then install the appropriate driver as root
  3. Now use modprobe to insert the module/driver into the running kernel.

[ root@localhost ~]# rpm -Uvh kmod-forcedeth-0.62-1.25.1.el5.elrepo.i686.rpm
[ root@localhost ~]# modprobe forcedeth


[ root@localhost ~]# rpm -Uvh kmod-forcedeth-0.62-1.25.1.el5.elrepo.x86_64.rpm
[ root@localhost ~]# modprobe forcedeth

Now that the driver is installed and running you can use the Network Setup Tool (system-config-network) as root to setup the wired device.

4.2. Wireless

Wireless works fine when using the latest madwifi driver. The wiki already has a nice HowTo page on how to proceed to enable your Atheros AR5007 EG device, so it will not be duplicated here.

Please see this page for the HowTo:

5. Graphic

Go to nvidia.com and download the linux drive for the GeForce 8200M (180.51). Make sure to reboot into runlevel 3 and to install the kernel-headers and kernel-devel of your kernel version.

Follow the instructions of the installer and all should go well.

6. Audio

Audio is already setup and working during install, however the sound is very scratchy and has a bad reverb at times. The driver used is the snd_hda_intel which according to the Alsa website is correct but no options have yet resolved the scratchy sound or reverb. Will have to wait for next kernel update I suppose.

The alsa download page can be found here.

The alsa compile and install documentation can be found here

7. Issues

While using madwifi driver you will probably have to manually turn on the wifi via the wifi button next to the power button on every start or reboot. The state (on/off) of this button setting is saved in other drivers and not lost on reboot. Hopefully the kmod-ath5k rpm will address this.

All sound issues are resolved by upgrading to alsa 1.0.20. Hopefully we can get that version in CentOS 5.4?
