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.
Another option could be to have a couple of drives...
I suppose that I could
use two boards (the DQ696 and one RQDX3) in the PDP-11/23 PLUS... and I have
one MFM drive from one old PC ready to use.
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.
This last question make think in something that
I've read in some place or
file... Is it neccesary to start up with XXDP to format the MFM drives
connected to one RQDX3 ?
You will need to format the drive if it's not yet been
formatted on
for a RQDX3 or something compatible, e.g. a MicroVAX. There is a
stand-alone version of the XXDP formatting program for VTServer (I say
"stand-alone", you still need to use boot.dd to load it).
