I forgot. I had that too. The firmware is supposed to specify which bank
and SIMM is faulty. Another reason to not love these machines:
If SIMM 0 has failed, the firmware reports a failure in SIMM 0.
If SIMM 1 has failed, the firmware reports a failure in SIMM 1.
If SIMM 2 has failed, the firmware reports a failure in SIMM 3.
If SIMM 3 has failed, the firmware reports a failure in SIMM 3.

I might be willing to swap my AS1000A RAM (some of which may be faulty and
I probably can't test it unless I can resurrect one of my machines briefly)
for memory for a PWS 500, Alphaserver 2100 or an Alphaserver 800.
