Subject: RE: AlphaStation 200 NVRAM Problem
tests.
Perhaps VMS could be working around correctable memory errors that
SROM is not able to cope with? If this is the case,
$ SHOW ERROR
That just says:
%SHOW-S-NOERRORS, no device errors found
One possibility I have in mind is it's something peculiar about DRAM.
As you may have been aware DROM code isn't run directly, it's loaded
by SROM into DRAM. If it fails a specific bit pattern at a specific
location some reason, then you might see symptoms like these. So
shuffling DRAM modules might change something here.
I will give this a go, but it seems unlikely as the machine is able to
run VMS, and I assume it must be passing at least some basic memory should give a clue and there should be further
information in the error
log.
(I'm not sure how you display that since the
functioning of $ ANALYZE
/ERROR got messed up on Alpha some time ago.)
I tried SHOW MEMORY, but that seemed good. ANALYZE/ERROR said I should
install DECevent and run conversion utility. Not sure about that one.
