serial port,
I don't
know if it applies to the AlphaStation 200 but I have a PWS
500a
which
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 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).
Just wondering if I should expect anything on the serial port or on the
monitor if my AlphaStation has an NVRAM self test failure. Anyone know?
I still need to identify the NVRAM chip(s), although replacing them means
learning how to desolder and resolder surface mount stuff, which I have
never done before.
Regards
Rob
