Ok, here's a wierd problem that has me stumped.

Custom built machine I threw together from spare parts, put in a hard drive that had a very limited Redhat 9.0 on it. I've been trying to install a new OS on this hard drive, but here's the thing:

I set the BIOS to boot from CD, but then the system won't recognize ANY OS cd except for Redhat CDs. I've tried booting from Win95, WinNT, and Slackware cds, and it fails to recognize them each time. Pop in a Redhat 7.0 or 9.0 cd, and it begins installation with no problem.

What in the world could cause such a thing? Until I figure this out, I'm stuck with a system that I can only install RedHat on!

(Pentium III 1GHz processor, standard 52x cd drive, 10gb HDD)
