Are you trying to install on a machine that doesn't allow booting from CD? There is a boot floppy using smart boot manager that allows you to boot from a cd on systems that don't have the option. http://btmgr.webframe.org/
[chaz> ] Correct, the BIOS will not boot from the CD. I'll take a look at the smart boot manager. I was assuming that the CentOS folks had a canned solution, probably using grub.
Untested as my machines all boot from CDs, and some don't even have floppies any more, but you can create a grub floppy, optionally with a menu interface. See script below.
After creating the floppy, mount it and edit the grub/grub.conf file to contain the following stanza (last two parameters on the kernel line may not be necessary, ramdisk_size might need to be increased):
