Subject: Note on Updating the Kernel for the Fedora3 tcs3 computers 
   Date: 2005-01

0. Intro

Updating the kernel require a bits of extra work due to:
   1. We develop our own modules (pmac.o) -> recompile after kernel upgraed.
   2. Install NVIDIA drivers for twinview support -> reintall requires after kernel upgrade.

Notes on upgrading from the 2.6.9-1.681_FC3 to 2.6.10-1.737_FC3

1. Install all installed packages using yum.

   yum installed new kernel 2.6.10-1.737_FC3 -> need to do additional work for
   new kernel.

2. Modify /etc/inittab to not boot into X.
   Disable loading of pmac.ko module in /etc/rc.d/rc.local
   Modify grub menu.lst under / to boot the non-smp kernel (smp kernel hung on boot).
   Reboot.

3. re-Install the NVIDIA driver. Must be done after compiling new kernel.
   Downloaded new driver from www.nvidia.com, version x86-1.0-611 (aug 2004)

   # cd /home/tcs3/public_html/systems/tcs3/computers/linux/0501-nvidia
   # sh NVIDIA-Linux-x86-1.0-6629-pkg1.run.txt 

   (complained about Riva supported, but worked anyway).

   Modify /etc/inittab to boot into X.

5. TCS 

  Needed to remake /dev/pmac device:
     #  mknod --mode=666 /dev/pmac c 66 0
        or 
     #  mknod --mode=666 /etc/udev/devices/pmac c 66 0

  Recompile and test tcs3 main.
  Install into /home/to and load pmac.ko at boottime -> /etc/rc.d./rc.local
  Run TCS3
