Well, at least I fixed this issue.  The autostart switch was already 
selected on this sIDE (which is noted in the manual to have off when the 
ROM bank hold HDB DOS).  I disabled it, and now I can perform disk 
commands with any slot selected.

I was worried that somehow I had mis-read the MPI schematics.
