But to be sure, I attempted to boot with a KNOPPIX CD and found I
cannot boot from my CDROM.
The boot process goes directly to the FC4. I poked around trying to
understand 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 was
by 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.
