VW 320 POST loop - Pierrot_SGI - 10-24-2020
Hi
I changed the motherboard of my non working VW 320 and put a brand new battery in it and at boot I have a kind of loop on blue screen POST telling me that date is out of range.
Keyboard is not responding ( I am using and Apple USB keyboard)
So how can I fix this ?

I only found this: https://arstechnica.com/civis/viewtopic.php?t=723072
Claims a PROM command called: recover_nvram
to reset PROM to defaults, but I assume you cannot access PROM?

An old thread, but no good answers, so I'll offer my advice from experience in case that ancient Ars thread ever gets taken down.
I recently acquired a 320 with the same problem, but the problem only appeared under the following condition: a new coin cell battery was installed before the system clock was set.
This is to say that in my case, I could set the system clock in ARCS after powering on the machine without a battery installed. Shutting down the machine and leaving it connected to wall power would preserve the time. At this point I installed the coin cell battery and had a successful starup test. Once my 320 was working to my satisfaction, I disabled the startup tests
Hope your case is as simple as mine was.

May be unrelated, but FYI...
My C8000 does not detect my Apple USB keyboard and boots to serial console, but it detects my Model M DIN-toPS2-toUSB and the HP keyboard that came with it.
The Apple USB keyboard works with every other computer I own otherwise.

Apple USB keyboards aren't compatible with earlier USB standards and sometimes don't work on other vintage boxes, i.e. my Tezro
You should get a more universal USB keyboard like a Pluggable Performance with Cherry Blues

I've often used an Apple G4 usb keyboard with my 320 and it works perfectly!

Just mentioning because another day I was discussing with a commenter on youtube and he was not getting the local console up on his C8000 and, after switching keyboards, it worked.
I try never to assume that something is common knowledge.
I even keep an old Logitech serial mouse around just in case.

Serial Logitech M-CAA43 is still my daily driver...
They must have thought they were onto something, its got two patents and its own serial number...

Mine is the Logitech M-M34.
I got it because I liked the software - it allowed you to assign tasks to pushing both buttons at the same time.
It replaced an IBM PS2 mouse.
I have it since 1997 but hardly ever use it these days.
When I passed the entrance exams to the military school, my father got me this mouse + 8MB of RAM. XD
