CMD MSCP SCSI problems? (again?)

[Dave McGuire <mcguire%neurotica.com@localhost>]

  I've just finished installing NetBSD 9.3 on a VAX 4000-705A using a 
CMD CQD-220 MSCP SCSI host adapter.  I put them install disk image on a 
ZuluSCSI board, it booted and ran the installer just fine, but when 
trying to boot the newly-created system disk (also implemented via the 
ZuluSCSI SSD) it fails to find the controller and thus cannot mount its 
filesystems.

  I remember something like this from probably twenty years ago, but I 
thought it was long since fixed.

  The disk subsystem works fine; I installed VMS on it this morning via 
the same mechanism and it's rock solid.

  Does anyone have any suggestions?

             Thanks,
             -Dave
