I have been trying without success to connect a Seagate ST42100 (Wren 9)
disk via the SCED SCSI bus on an S81 running PTX 1.3.  The kernel finds
the disk when it probes the bus at boot time and outputs a message

    WARNING: sd: not a supported embedded SCSI disk, target2, unit 0

It then refuses to have anything to do with the disk.

I have added the files /etc/diskinfo/wren9.{scsi,geom} and /etc/vtoc/wren9,
but it still doesn't work.  In desperation, I tried scanning /unix for the
Product Code strings for the supported sd disks mentioned in the 1.3 release
notes (CDC 94161 and Fujitsu M2249S).  I can't find them, and am now even more
confused.

Can anyone tell me if it's possible to add third-party disks, or are you
restricted to those supplied by Sequent? :-((

Please reply direct to me, and I will summarise.

Thanks.
