9386.0. "Wide bus on 3.2c?" by HAGGLE::dorian (Tim Dorian) Thu Apr 03 1997 15:56

Will DU 3.2c support scsi wide disks. I have an alcor that's running 3.2c
on a wide bus (2 ba356's) linked together. Will this work?

9386.1YES and NO...SMURF::KNIGHTFred KnightFri Apr 04 1997 10:4510
Yes, wide buses work.  Data is transfered from wide
devices in wide mode, and data from narrow devices is
transfered in narrow mode.

The only catch is no wide addressing is allowed yet.
All SCSI addresses must be in the narrow range (0-7).
You will eventually be able to use scsi ID 8-15, but
not for a while (it's planned for the Steel release).

Well that explains why I can see the devices at the console but NOT when I boot
the generic Kernel. This makes daisy-chaining the ba-356's usless.

Drats,

Not completely.  Remember, you can still put 5�" bricks
in the BA356 (which would require daisy chained boxes to
get a full bus of just 8 devices).

And when Steel comes along.....
