Subject: Re: AlphaStation 200 NVRAM Problem
which
I tried starting up my AlphaStation 200 today. All I get is some beeps
and an LED diagnostic code that suggests the NVRAM test failed. I
swapped the battery, as the old one was dead, but it still refused to
work. I have tried connecting to the serial port and got nothing
(although I could have a problem with using the correct cable etc). I
even tried flipping the jumper that takes you to the mini console, to no
avail.
Does anyone have any suggestions for reviving this machine?
I don't know if it applies to the AlphaStation 200 but I have a PWS 500a defaults back to the AlphaBios firmware whenever the
battery dies. After
replacing the battery, I have to connect a keyboard and monitor and go
through the AlphaBios menus to reset it to SRM. (If I don't replace the
battery, it lets me go through the motions of resetting it but it never
starts
SRM.)
I believe this reversion back to AlphaBios does indeed apply to the
AlphaStation 200 too. But in my case nothing appears on the monitor and
nothing appears on the serial port either, I just get some beeps and a LED
diagnostic code. It is possible that I have a cabling issue with the serial
port, but I did try a few combinations. If I know that I should expect
output on the serial port despite an NVRAM self-test failure then I could
investigate that further with my breakout box (don't have a protocol
analyser).
