There where a few "non-ATAPI" CD-ROM drives around back then with the interface simply not compatible. Don't know the details after more than 15 years, but it had to do with the controller chips (either there was one on the SB card that didn't go along with the one on the drive or the other way around). There were also some SB cards that in fact had SCSI controllers on them, for use with SCSI based CD-ROM drives only. I used to have one of those back at the company I was employed at from '85-'94, actually 'borrowing' a SCSI CD-ROM drive from a Sun "Pizzabox"...
