[SunRescue] SS1000 Disk Board

I have 2 of these in my SS1000 as well.

I have never been able to figure this out either.  The docs I have don't
tell me.  I put the SCSI cable from the SCSI card to the IN, then put a
terminator on the OUT connector, and it works.

My guess would be power?  The SCA drives that go in these have no external
power connectors - the power for the drive comes thru the SCA connector
itself.

I don't know.
