It is a SCSI-2 narrow (50-pin) device. It uses a HD-centronics->50pin-centronics cable. I believe the BIOS on this machine really does not like and IDE disks connected. It does have an IDE controller but will only allow the CD drive on it, so we have a PCI/IDE controller installed to handle the single IDE disk. The machine refuses to boot off the IDE but LILO is happy to do so off a floppy. BTW, I only have this machine in order to test out software on a 4-way SMP machine, which is why we passed on installing more expensive scsi disks. Now, when I connect the cable to my tape, lilo fails to boot off the floppy. It seems that the first BIOS disk (80h) which is detected properly by the IDE controller is trashed by the scsi controller (which initialises later than the IDE). So we now boot off the floppy directly (i.e. the kernel boots off the floppy, not just lilo). Finally, now that we are booting just fine, and the scsi tape drive is clearly detected at bootup by the kernel, I see that the scsi driver does not stay loaded (maybe the boot process loads it, and if there are no disks it unloads it?). So I try to load it myself modprobe sym53c8xx and this kills the machine. By "kills" I mean the machine stutters for a few seconds, and then locks up, not even vt switching.
