You didn't mention any IDE devices, so I'm going to assume you don't have any. Question 1: Have you ever booted off that CDROM drive? Are you sure it can be done at all? Question 2: What are your SCSI settings? On my SCSI system, it goes "Boot, option to do BIOS setup. Probe SCSI card, option to do SCSI setup. Etc." The SCSI settings have to tag the CDROM drive as bootable. Further, the BIOS settings for this are "Boot from SCSI", whether I'm booting from the disk or CDROM on the SCSI chain.
