I used same configuration with different CD-ROM drives.

We have tested a 15-foot long ribbon cable plus another 3-foot long SCSI cable with a 4GB disk and a 2GB disk or CD-ROM without terminator on many machines and disks. To isolate the problem, first thing is to make sure you CD-ROM working. If CD-ROM drive is OK, then make sure the IRQ for NCR is not conflicted with others. If you got error on NCR irq, it almost 100% makes system failure. -- /-------------- Jin Guojun ------------ v ---- Internet: g_jin@lbl.gov ----\ | Imaging & Distributed Computing | Usenet: ucbvax!g_jin@lbl.gov | | Lawrence Berkeley Laboratory | Bitnet: -- | | 50B-2239, Berkeley, CA 94720 - jin%george.lbl.gov@Csa3.LBL.Gov |
