I've brought up a MicroVax II and installed VMS 5.5-2 on a SCSI2SD disk
and it is fun to work with. (I also installed openvms 7.2 without much
drama)
The problem I am having is that is has a TK50 tape drive and controller,
but it never has shown up in the device list. I even swapped in a
different controller.
The DHV11 did show up initially but has now disappeared from the device
list. Did I do this by removing boards and putting them back in?
A RQDX2 board was put back in at a secondary CSR address and that shows
up (it is connected to an RX50 which shows up in the device list).
Does Autogen recognize new hardware?

A lot of Unibus/Qbus devices have "floating CSRs" which means they don't
have fixed address assignments. Instead, the correct address is based on a set of rules,
which puts devices in an ordered list and assigns addresses in sequence. There are tools
to help with that. If you get the address wrong, the system will see the device as the
wrong type, and either fail to talk to it, or not talk to it at all (if it's not
something the OS supports).

What type of cab? BA23 or BA123 'world box'? In the BA123 the left 4 slots
from the left are CD interconnect, in a BA23 just the
left 2. CD
interconnect means you can put a half-height card in the 'top' of
slots 1-4
(or 1-2) and not need anything in the bottom. Which slot are you putting the
TQK50 in?

If there is none, or a faulty, TK50 drive attached the controller does

If it's an MSCP controller, it would go into the UDA50 floating CSR position. DHV11
and TMSCP rank later than UDA50 in the floating CSR order, so if you added a MSCP
controller without adjusting the CSR address switches of those two cards, they would not
be correctly recognized as I discussed in my earlier mail today. The order of the cards

I think you have a good point about CSR addresses. There is a CONFIGURE
tool that tells you what set the addresses to for a particular
collection of options, I need to run that and then check that all the
devices are set to the proper addresses.
I suspect that I don't see MUA0 show up because the tape drive is not
working properly.

To make matters confusing, there's an aspect of floating CSRs I did not mention
before. Some devices -- MSCP disk is one, TMSCP tape also I think -- have floating CSRS
for the second and subsequent units, but the first is fixed. Others, like the DHV11, are
all floating (including the first unit).

The TK50 still does not show up, I think it is because the tape drive is
not functioning (can't move the lever to allow a tape to be loaded).
However, I do have functional RX50 floppys, just need some media. I
have a couple spare TK50's and will try those to see what happens.

Here is one example of how the expected floating CSR address and

MSCP controllers instead of 1:

When I started this I hadn't put the RQDX2 back in, so I had only one
UDA controller and that's how I saw the DHV11 show up. When I put the
RQDX2 back in that's when I lost the DHV11.
I did the configure from VMS 5.5, it was a lot less verbose than what
you showed.
At this point I am wondering why I am fussing over such useless

Of course to the hobbyist the answer is "Because they are there!" and
you better get them working. I would be better off with a DELQA, BTW
will the cabinet kit from a DEQNA work with the DELQA?

If you are not familiar with the BA23 or BA123 enclosures, make sure you aren?t plugging
the controllers in the PMI slots.
This would be 1-3 CD on the BA23 and 1-4 CD on the BA213. Things will be very unhappy if
you accidentally do this.

Yes, definitely. Some older devices have switches (or even
soldered jumpers) to set the CSR address. If some of these
are wrong, it could mess up the automatic address assignment
of later MSCP hardware.
Another possibility is dirty backplane/board contracts.
Also, some LSI-11/uVAX hardware may be in the age where they
are dying. Many later devices will not show up on the bus
if their internal microcontroller fails.
If the peripherals have socketed chips, you might try
reseating those chips.

Not exactly.
VMS automatically looks for and initialises I/O devices at startup
time. (There are exceptions to this but these do not come into
play in this particular situation.)
Autogen is another thing entirely. It is a tool which you run
manually to set system parameters. You don't have to run autogen
to pick up changes in your I/O setup. You just have to have your
device configured the way VMS expects them to be and VMS will find
them when you boot.
It won't if you do a minimum/conversational boot (STARTUP_P1 set to "MIN"),
devices won't be discovered unless the STARTUP CONFIGURE process runs. After
a minimum boot you need to MC SYSGEN AUTO ALL/LOG to pick up devices. Or
just do a full boot.

Does Autogen recognize new hardware?
Yes, definitely. Some older devices have switches (or even
soldered jumpers) to set the CSR address. If some of these
are wrong, it could mess up the automatic address assignment
of later MSCP hardware.
