SIIG Ultra PCI SCSI Controller + CDROM devices

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.

Thanks,

Okay Hal, the easiest way would be to take this from the top.

1. Make sure that the SCSI card has its own SCSI address set porperly and that it is properly seated and fastened to the case. It needs it's own ground.

2. Make sure that the drivers to load the SCSI card are properly loaded and that you can access the SCSI Bios setup software. These should be loading in your autoexec.bat and config.sys until protected mode drivers take over such as in Win95 or NT.

3. Make sure you have correctly identified with their own respective ID's each device in the SCSI chain.

4. Make sure that the last device is properly terminated, either through hard pin type terminations, a physical terminator attached to the ribbon cable or the last device permits it, that software termination is occurring.

Let me know how you make out!
