The SH204 host adapter boards will only access SCSI device 0 (it's in the hardware) but with little work, the ACSI (DMA port address) can be changed anywhere from 0 to 7. The disc interface board is talking to a Maxtor 380 meg XT-4380-S SCSI drive, and the tape is a CYPHER CT-540 SCSI 5.25 inch cartridge tape drive. I use the Supra v 2.06 (I think?) driver with the controller and drive defined as 'other'. The tape driver is code that I wrote that installs itself as a TSR attatched to BIOS trap 13 RWABS calls. I wrote a unix like TAR program that I use to perform backup , restores as well as file transfers from my ST to UNIX system and vise-versa. I believe you need the 'new' SH204 adapter PAL's tho. ----- Paul Moreau UUNET: ..!ccicpg!unix!paulm
