We just got a Maxtor Tahiti II optical drive from Parity Systems, and
I'm having trouble getting it going. I remember that a while back,
someone posted about this, and gave the DIP switch settings he used,
but alas I did not save it. The #^%$&* instructions from Parity are
not helpful, to be generous; they only mention the device ID switches.
I've set the ID, and properly hooked up the drive (plus terminator).
When I boot, 'hinv' reports an optical drive in the appropriate place.
I remembered reading that it was possible to avoid using the Parity
drivers and just use the regular SCSI disk drivers, so I thought I'd
give that a try. I tried running 'fx' with a new cartridge, and it
seemed to successfully identify the drive, and gave some messages
about creating default partitions and so on. The disk label looked
OK. But when I went to exit from 'fx', I got an I/O error with the
following messages in /usr/adm/SYSLOG:
> Dec 14 13:50:46 hyper unix: sc1,5,0: cmd=0x8 Unexpected info phase 46, state 49. Resetting SCSI bus
> Dec 14 13:50:46 hyper unix: PMO87: read error on block #0.
> Dec 14 13:50:46 hyper unix: Error detected on PMO87 due to command <dis/allow medium removal>: unit attention : Power on, reset or bus device reset occurred
So, I thought I'd go ahead and install the Parity driver and rebuild
the kernel. That seemed to work, but when I run the 'pmoinfo' thing,
even with just '-c INQUIRY', I get an I/O error the first time, and
the second time seems to block in the kernel. I suppose I'll log a
call with Parity, but if anyone could send me their DIP switch
