-When I installed Interactive Unix 2.2 I attempted to use an ST-506 primary
-controller and an Adaptec 1542B SCSI controller as secondary.  After
-a *day* of re-building kernels and plugging and un-plugging controllers,
-with nary a kernel that would boot, I gave up.  Fortunately, the SCSI
-controller has floppy ports, so I decided to toss the ST-506, two MFM
-drives, and use only the SCSI.

-work!

I agree.  The documentation and menus indicate you can set up a primary ST-506
and a secondary SCSI, but what I tried was the opposite:  having an old ST-506
controller and drive available as secondary.  My attempts, too, failed.

Anyone had any luck with this?  Followups to comp.unix.i386.
