DKA500.
Might be a red herring Rob, but I seem to remember certainly for the
BA356 integrated into the Alphaserver 1000A that the enclosure could
be operated in a split bus mode where half the enclosure was on one
bus and the other half on another.
Just a thought (you might want to cross post this to comp.os.vms).
Mark.
I posted this to comp.sys.dec and someone told me there about the split
bus.
I will check this.
Thanks
Rob
I have confirmed that it is indeed working in split bus mode. It seems I
need a BA35X-MF jumper module to get it to work in single bus mode.

Rob
This
time, after the reset, it recognised both the CD-ROM (ID 4) and
the disk that was at ID 0 and now was at ID 5.

Rob

The QLA1040 isn't differential is it? The soft_term should be just
'on' I
think.
