This was the case. I was counting the "open" writing on the switch block 
as a 0. Maybe they put the blocks in upside down.

In any case, I switched the board to the default setting of 160440, and 
on boot the board DID get detected. dhu0 dhv etc.

Thanks for your help.

Now I have to figure out why the board had been installed at that 
address. All the stuff in the machine is stock except for an Emulex QD21 
controller. All seems to work fine so far. I will let it run for awhile 
and see how it goes before switching the board back.

To test the dhu0 ports, I then went to /dev and did a MAKEDEV dhu0. This 
created new devices ttyS0 through ttySf.

I then went to /etc/ttys, changed tty00 to ttyS0, and turned the port 
"on". I rebooted the system (suppose I could have just done a "kill 1 
-HUP) and noted that a getty process started on ttyS0.

Am I on the right track???

I lack an appropriate cable (Female/Female null modem) and so will test 
this to see if I get a login prompt on the port.

In the meantime I will endeavour to compile a custom kernel using the 
board's original address, just in case there was some conflict that 
caused DEC to set it that way in the first place...

As an aside, when I go to /usr/src/sys/arch/vax/conf, modify GENERIC, and 
do a "config" I get about 30 "syntax errors" from the file 
"../../../conf/vax/files". As I'm not a "config" expert, can you tell me 
what's wrong?

I would be interested in finding out the encoding of the switches on the 
M3104/DHV board as well.

Thanks for the help, 

Kevin
