Yes, IDE-fix'97 from Aminet has that device driver in it. I've tried them all, and they all detect the two ATAPI CD drives that I tried with UNKNOWN (SCSI?) DEVICE. It could be that I was really unlucky to have 2 drives which definitely are not compatible, but who knows. :-?
When you use FindDevice, does it report the right model number and manufacturer name in it, or do you get garbage like me?
