Turns out I incorrectly configured NIC failover in my ESX config ;)

I'm doing FreeBSD in ESX.

What is your guest OS? I have learned that for running emulator-on-vm,
Windows XP works best. The worst is NetBSD and the kicker is that it is the
only modern OS that runs TME easily.

It seems the network issues I was seeing had absolutely nothing to do with 
SIMH...and everything to do with the fact somewhere in my VMware system 
packets were being duplicated...

Re: [Simh] EXT :Re: Ultrix 4.0 and DEQNA-LOCK

[Johnny Billquist]

Maybe to vlarify myself. DEQNA-LOCK is not something I would expect 
Ultrix to turn on, and the code Ragge posted certainly reported it 
without appearing to modify it. And it would not make sense to modify it 
before that point, and if it was changed after that point, dmesg should 
not report it.

I also see other posts showing Ultrix 4.5 also running in DEQNA-LOCK
mode. Maybe Ultrix was never upgraded to use the DELQA and DELQA-Plus
enhancements.


Well, as others pointed out, the normal operation/programming of the
DEQNA and DELQA are the same.

The DELQA-PLUS is a different story. But that's not what we're dealing
with here.

So, it really works pretty much the same no matter if it is a DEQNA or
DELQA. The differences have more to do with some built-in MOP handling
in the DELQA, along with the ability to perform network booting, which
the DEQNA cannot. Also some watchdog functionality.

So yes, I would indeed expect that Ultrix would treat the DEQNA and
DELQA the same. And if it don't have a driver for the DELQA-PLUS, it can
run that one in normal DELQA mode as well. The DELQA-PLUS mode is
better/more efficient, but that is the only one with a different
programming model.

Cory, could you post the output from showing the device in simh?
I wonder if there might be some confusion about how to turn off lock
mode. I've never even tried modifying that. By default, I would
assume it would be correctly configured, meaning it should work
right if you don't try to "fix it".


I am doing SET DEQNALOCK to OFF, and SHOW XQ (in my initial posting
shows that IIRC) with it in DELQA mode, and later on after probing
and initialising it, despite DEQNALOCK set to OFF and showing as OFF,
SHOW XQ shows it has reverted to being in DEQNA mode.


No. You initial posting showed the dmesg output, but not the simh
input or output, unless I'm very confused.
