Recently I get a CD-R SCSI drive and a "rare" ISA Card. This card provides SCSI+IDE+Floppy interface. It has a TMC-1800/18C50 (SCSI) and FD37C75 (IDE) chips with Future Dommain SCSI BIOS (ver 3.0 - 1992), but I have a problem in DOS.
I plug the CDR drive to SCSI card, and the CDR drive is recognized under MSDOS. If I insert a Audio CD works properly but If I insert Data CD doesn't work. I thought the CD-R is not working properly, but I changed with another SCSI CD drive and it happens the same. After that, I changed the Future Domian SCSI card for Adaptec and the two CD units work properly: Audio and Data CDs.
I believe the problem is the CD driver. I had Power SCSI version 4. The card came without drivers. Does anyone know if there is a newer driver version for TMC-1800/18C50 chips in MSDOS?
Thanks in advanced
