He's using a Dilog DQ696, which supports two drives. Some other
ESDI controllers (Emulex MSCP controllers come to mind) also support
logical partitioning to present a single physical drive as multiple

Dilog DQ696 can do that.

Aha, I see. I
think that I shall begin with the installation of
BSD 2.11.
The ESDI drive has 739 Mb of capacity... I guess if could be
possible to
define more than one partition ar PC style...
2.11BSD supports disklabels for partitioning, but there's no
"universal" scheme supported by all operating systems. You may need to
get creative in order to get more than one OS on a single physical
disk. You can't just hook up any old MFM drive to an
RQDX3, unless you want
to calculate the parameters required to format it. It can be done, but
it's not exactly straight forward. The DQ696 may be more flexible in
that area, I don't know.
It is, FYI. (for ESDI drives, that is)
