Well luckly the roms were up to date but unluckly that didn't fix the
problem. I ended up solving the problem going back to a 2.4.18 kernel from
kernel.org. Something redhat patched their 2.4.18 kernel with is also in
2.4.19 and the fix in the 2.4.19-acX and 2.4.20-acX patches would cause the
kernel to lock on boot. We just had to patch the driver to the eepro1000 to
it and we were readt to go. thanks for the the advice though. I'm sure
linuxbios would be much easier to upgrade remotely.
