I have been trying to get a 3Com Unibus Ethernet controller working
on our Vax 11/785 (which is running 4.2BSD). The problem is that when
I try to boot the kernal configured for the 3Com board the system hangs
up and will not completely boot. It hangs while probing our tape drive.
Output on the console:

(I am wondering if that turkey dh/dm could be the problem, it has
caused us headaches in the past....)
I have the switches on the 3Com board set as follows:
9 8 7 6 5 4 3 2 17 16 15 12 11 10 SG BYT X X X 8 7 5 4
--------------- ------------------------ -------------
o o o o o o o o o o o o o o o o o o o o
n n f f n f f n n n n n f n n n n n n n
f f f f f
And the following jumpers are set:
J1 J4 J2
My config file contains the following lines:
pseudo_device inet
pseudo_device pty 48
pseudo_device ether
device ec0 at uba? csr 0164330 vector ecrint eccollide ecxint
When I contacted 3Com they simply told me that they provide no unix
support. (????)
If you can confirm that my switch settings are correct, or advise me that
they are not, it would be most helpful. Any help at all will be gratefully
received.
Many thanks in advance,
Scott Mulligan
ps: The manual is dated 1982 for whatever that is worth. thx agn -scott

Nope, I believe it is the turkey 3Com board which has to be configured before anything on the Unibus which might want Unibus memory (it isn't very flexible as you put the start of its Unibus address space in the switch registers). You need to coerce the system to configure the 3Com early. Since the disk configuration code in unifind() (vax/autoconf.c) is separate from the other-devices-on-the-bus configuration code, simply move the disk configuration code down below. Also, if you want things to work after a Unibus reset you may want to move the lines in ubareset() (vaxuba/uba.c) that look like: #ifdef INET ifubareset(uban); #endif above the "for" loop. NOTE: Also, make sure your ECMEM definition in vaxif/if_ec.c conforms to what you have in the switch registers. If you have any other questions, call or mail to me. We are also running the 3Com on a 785 (although I just got our Interlan replacement). -- bob tomlinson dspo!tomlin@lanl.arpa (505) 667-8495 -- Bob Tomlinson - dspo!tomlin@LANL or {ucbvax!unmvax,ihnp4!lanl}!dspo!tomlin Los Alamos National Laboratory - E-10/Data Systems Los Alamos, New Mexico - (505) 667-8495
