But to be sure, I attempted to boot with a KNOPPIX CD and found Icannot boot from my CDROM.The boot process goes directly to the FC4. I poked around trying tounderstand and found(1) /boot/grub/device.map has two entries -- fd0 followed by hda(says it was generated by anaconda)(2) /boot/grub/grub.conf lists FC4, FC4-install, and DOS (which wasby the way long ago corrupted and is now useless)
(3) BIOS lists three boot devices in order CDROM, FLOPPY, and HDD-0

I have a DVD drive and a CR-RW drive internal.
Looks like your BIOS is capable only of booting from the first CD-ROMdevice. Your BIOS cannot boot from your second CD-ROM device (yourDVD-RW drive).

A lot of BIOSes have a quirk that if you have only a secondary device onan IDE bus they can see and report the device OK, but they will not bootfrom it. Could that be the case here? If so, just jumper it to be themaster.
