Update the "CD-ROM not configured" question.

"It would be good to point out that a machine that only has SCSI devices
may also generate this message if an IDE CD-ROM is not configured as
the Master device. Words like these might work ..."

This generally means that there is no CDROM in the CDROM drive,
or the drive is not visible on the bus. Feed the drive
something, and/or check it's master/slave status.
