You DEC old-timers out there will probably chuckle at my little
"discovery", but I'm posting my findings for us who are "DEC
challenged"....
Yesterday I was pulling my hair out trying to get my VAX 4000-500 to
recognize an external RRD-43 CD-ROM that was attached to a KZQSA SCSI
adapter. No matter what I did, it wouldn't recognize the fact that anything
SCSI was connected.
The problem turned out to be the address that the KZQSA was set to. It was
set to address 761400, and the 4000 was reporting the card to be a DEFQA,
which to even a DEC newbie as myself, was VERY wrong. A search through the
"VMS wizard" archives at Compaq.com turned up the statement that the KZQSA
was shipped with a default address of 761300.
So I fiddled with the address jumpers and set it to 761300 and *voila*, the
4000 found the KZQSA. I hooked the external SCSI enclosure to the card, and
it found the CD-ROM.
It was able to boot VMS from the CD, and I'm on my way.
Again, don't laugh too hard, I hope this message helps others who are
"Unibus Ignorant"....

I suspected as much, but I didn't have the expected address of a KZQSA at
hand, so I couldn't check.
So I fiddled with the address jumpers and set it to
761300 and *voila*, the
4000 found the KZQSA. I hooked the external SCSI enclosure to the card, and

Congratulations.

*Ahem* The VAX4000-machines are just as Unibus ignorant as you are. They
have Q-bus. :-)
However, the addressing scheme DEC developed for autodetecting hardware on
the Unibus was carried over to the Q-bus as well.
And note that the KZQSA *might* be expected to live at another address if
you have certain other pieces of hardware in the system. :-)
I'm sure someone have the ruleset available online and can post an
URL. :-)

Well, for a NetBSD system with package sources installed, here's one:
<URL:file://localhost/usr/pkgsrc/sysutils/sysgen/DESCR>

New subject: VAX/VMS and Sysgen addresses
A little later on I was involved in moving some
peripherals between Qbus
VAXen running VMS. I remember pulling an MSCP-type disk controller card
and having the tape drive disappear. Because when you had fewer disk
controllers then VMS expected to see other controllers at different
addresses. And there was no way to tell it 'Look you stupid thing, the
tape controller is at addrsss xxxxxxx'. I had to reset the address
switches/jumpers on just about every card in the system.
Actually, Tony you could go into VAX/VMS sysgen and give the address and
vectors for almost anything and have them work... the trick may have
been with the MSCP type card which has a programmable vector which may
have conflicted with something else, but in VMS 2.x-4.2 manual sysgens
could allow almost any devices to coexist...

My only other worry is that surely your machine is a Q-bus box???

If anyone needs to know a handy way to find out the addresses that
VMS will expect for a controller, and has a VAX running VMS (this
won't work on OpenVMS Alpha), run SYSGEN and use the CONFIGURE
command. For information on how to use the CONFIGURE command,
check HELP.
