Can you boot from ANY MSCP controller even if it
is third party such
as CMD as long as you have the correct ROMs?
If you just use the BOOT command or configure for auto boot there are
probably restrictions on how the CSR addresses and device unit numbers are
configured for the MSCP controllers. If necessary both the KDF11-B and KDJ11-B firmware
should let you specify a
non-standard CSR address using the BOOT command with the /A option as
documented in the manuals.
They can but usually not needed unless you have the primary and secondary
device addresses filled.
I haven't had any problems booting from Dilog and
CMD SCSI SCSI controllers
and Dilog and Emulex ESDI controllers using the standard KDF11-B and
KDJ11-B firmware MSCP boot.
Same here. I have a KD11J/A with RXV11, RLV11, RQDX3, in it and it
knows how
to boot them all for all the possible media.
I have a KDF11B (11/23+) that does that too.
I covered the one oddball I've made using dual width cards like The KDF11A.
Even that boots just about anything (dualwidth) so long as I put that
boot in
the MRV11 Eprom card.
The uVAXII has both CMD SCSI and RQDX3 and has no issues.
The older 11/23 boards and the LSI-11 boards including the SBC11 (falcon)
may need help booting devices that are newer than they are but generally
they do given the right boot program.
DEC Qbus systems did a very nice job in maintaining forward improvement
without blowing up the ability to use new and old hardware.
But, I also give the caveat that if you understand Qbus systems some of
the discussion
is already known and DEC did a very good job with their various
handbooks to educate.
I imagine those books are getting scarce but once they were very common
as DEC
literally handed them out. If you don't have them you should be
seeking them
in paper or on line. They are a vast record of basic and needed
information.
