I have a SIIG Ultra SCSI controller, and two CDROM drives, one of which is a CDR. Neither CDROM drive shows up in the BIOS, when it displays attached devices and their scsi ID. When I boot into DOS, NT, or Linux, The devices arent being seen. The light on the CDROM drives comes on when the BIOS passes by their ID. I think the BIOS is ignoring CDROM drives, and the Operating Systems that I use are trying to read from the BIOS. Any help on this would save me a lot of time and some hair.
