| I looked at a V4.4 kernel for the message, the libraries in
/usr/lib�and the programs in /usr/bin. I couldn't find anything
with "Power status update" in it.
But, then I checked /dev/mem and found it. My best guess is
that the Model 240 has a Prestoserve NVRAM which is where the
messages are coming from.�What's odd is that I don't think the
Personal DECstation supports Prestoserve NVRAM, but if it does,
that's a likely source. Odds are the battery died and the
NVRAM shutdown the system to prevent data loss.

Just a thought, is it possible that since the operating system was originally
built on the DECsystem 5000/240 that the s/w thinks that it has Prestoserve NVRAM
and the reason it's barfing is because it can't find any trace of it on the
Personal Decstation 5000/25 of the Prestoserve and therefore it just thinks it's
broken down, hence the shutdown?
Might there be something in the kernel/objects loaded/somewhere that's misguidedly
trying to tell the 5000/25 that it ought to be seeing Prestoserve?

| These messages don't come from any driver that I can locate.
I think I found them because the NVRAM is part of memory and
when I searched /dev/mem, they were there. Either this is
part of the supporting console code, or something in the
memory itself. If the original system is a Model 240, then
it should be easy to rebuild the kernel without Model 240
and Prestoserve support. If the original system is a Personal
DECstation, then it likely wouldn't have such support in the
first place. It couldn't hurt to clean up the configuration
file for what features and device are actually present, but
if that doesn't fix it, look at the hardware.
