My email server is running CentOS 3 and I can't upgrade it to CentOS 4 using the CD's. At first I thought it was the old Megaraid card (that's no longer supported), so I replaced that with a new card. I've tried ISO's from CentOS 4, 4.1 and now 4.2 which I've tested and booted in other machines. Just not this one.
if the cd-rom wont boot this machine, when it does boot on another machine - the most likely cause would be bad cd-rom or cd-rom cant read cd-media.
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.
you could try booting over the network using PXE or just use the kernel+initrd from the pxe images, add them to the local grub loader, boot into a network install.
It certainly something to try....
remember that there is no CentOS3 to CentOS4 upgrade path, you need to boot with the 'upgradeany' option and force CentOS4 onto the machine.
Perhaps, as has already been suggested, a fresh install might be better ?
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.

If you are having too many problems upgrading and don't want to start from scratch, why not stay put on Centos3.x ?
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.
