Summary: Solaris support for 3rd party sbus card

Thanks to Donovan Conrad and Chad Price for stating the obvious and telling
me to contact Performance Technologies. The board had always been serviced
by DEC so when I couldn't get the information I needed from DEC, I gave up.

I contacted and found two items of interest. At U20 on the
board there are 4 dip switches. If you close switch 1, the board switches to
Sun Emulation mode and has native support.

There also is a newer driver for Solaris 2.6, but it won't work if you boot
the 64 bit kernel.

I opted for the 1st item my Ultra's running a 64bit kernel with the array up
and running.

I've got a couple DEC Storageworks RAID arrays hanging off of Ultra 1 boxes.
The units have a differential ultra-wide SCSI connection to the host. As a
test, I did an upgrade install on one unit. Upon restart, I am unable to
load a driver for my SBUS adapter. The adapter is a Performance
Technologies PT-SBS440A. Previously, we used the DECptisp driver that
shipped with the array, but that driver won't load under Solaris 7. Any
know of a work around for this card? From the OBP I can see the adapter and
the array attached to it, but can't access it from the OS.
