Very Computer

I've got an IBM DORS32160 drive* off an NCR 53c810 controller
that negotiates for SCSI-I, 5mb/sec upon boot.  The drive should be
negotiating for Fast SCSI-II.  It's an Apple OEM.  

Anyone seen this or have any ideas why my drive is calling itself or
being taken for a SCSI-I device?

Just for the record, the DORS is at ID 0 with termination enabled at
the end of a chain also containing a Seagate Fast SCSI-II drive and
an HP35480 DAT.  The DORS has no jumper for enabling term power.  The
other 2 devices are supplying term power.  OS is FreeBSD 2.2-BETA.
No other flakiness has been noted.  All devices are internal with
termination supplied on one side by the NCR.  The DORS is the Ultra
narrow model.

Thx,
Craig

I have no trouble with mine. Here's one on a PPro-200 (just the DORS on
the SCSI chain) running 2.2-BETA:

        (ncr0:2:0): "IBM DORS-32160 WA6A" type 0 fixed SCSI 2
        sd0(ncr0:2:0): Direct-Access
        sd0(ncr0:2:0): 10.0 MB/s (100 ns, offset 8)
        2063MB (4226725 512 byte sectors)

And here's one on a P-133 running 2.2-961014-SNAP (also a 4 GB Barracuda
on the SCSI chain):

        (ncr0:0:0): "IBM DORS-32160 WA0A" type 0 fixed SCSI 2
        sd0(ncr0:0:0): Direct-Access
        sd0(ncr0:0:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8.
        2063MB (4226725 512 byte sectors)
        (ncr0:1:0): "SEAGATE ST15150N 0022" type 0 fixed SCSI 2
        sd1(ncr0:1:0): Direct-Access
        sd1(ncr0:1:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8.
        4095MB (8388315 512 byte sectors)

No problems in either case.

side issue, probably not related to your problem -
Why are you supplying term power from more than one place?

Are you using the SDMS V3.x or the SDMS V4.x BIOS?
