I guess that's possible, but wouldn't it crap out on the "Loading
vmlinuz....." part?  It freezes up right in the middle of kernel 
hardware detection phase.

It certainly something to try....

Whoops, I forgot to mention that in my email.  I'm not upgrading the 
machine, I'm going to wipe it out and install a clean copy of CentOS4. 
I only broght up CentOS 3 to show that the machine isn't 'broken' and 
I'm able to install linux on there.  It just doesn't like CentOS 4 for 
some reason.

Just to be clear, I am starting from scratch.  When I boot from the CD 
it loads fine but then freezes right after the kernel says something 
about the AGP video card.

And I want to upgrade for the 2.6 kernel and I also want to put reiserfs 
on this server.  The machine is getting a little old and I think this 
will help the performance for the next year or two before we retire it 
for good.
