In that case you wouldn't be able to use the disk from DOS at all. A sure
indicator is the "press Ctrl-A for SCSI-Select" message at boot.

I'd expect that this is rather a geometry translation problem - the 1542 and
the 2940 translate the SCSI LBAs differently to C/H/S and only the 2940's
translation is matched by the DOS boot block contents, or worse, its
position.

(I suggest we continue the discussion in private, anyone interested please
join, but someone will post a final summary anyway, I think)
