When I boot to 2.6, the message that comes up on the screen after dhcp broadcasting refers to the CD drive. And people doing regular HD installs are finding that their CD drive doesn't work.

What fixed mine was to make a change in /etc/fstab so that

/dev/cdrom was either

/dev/scd0 or

/dev/sr0 (which is symlinked to /dev/scd0).

Something else to check is the drive's mount point. Knoppix-installer builds /etc/fstab so that it's

/cdrom, which is the Debian way of doing things, but the desktop icon (using kdm, anyway) is

/mnt/cdrom, so you might want to change that in one place or the other.

While you're in /etc/fstab, if you want the CD drive to be mounted automatically (so you don't have to do it manually each time you boot), change noauto to either auto or just delete that word.
