The pass-through interface on the ida(4) devices is somewhat limited; I'm not sure you'd be happy with the performance if it worked. My solution has been to recable things so that the external bunkhead scsi connector attaches to the non-ida(4) SCSI card. This assumes your hardware has both. Adding a cheap Adaptec for the tape drive is the only other option. I do have all the info I'd need to write the pass-through though its quite low on my list. > I also have several 64-Bit/66MHz fibre channel host adapters > for COMPAQ machines, which I can't get to work until now. If these cards use the HP Tachyon fibre channel controller you might try looking for the information that was posted about a binary driver someone was working on. -- 10 40 80 C0 00 FF FF FF FF C0 00 00 00 00 10 AA AA 03 00 00 00 08 00
