Al,
I thought the problem with switching these chips was that part of the ROM code was
embedded in them? I.e. it isn't just an issue of battery? Am I wrong? If I am then why
not use one of the replacement chips that are available?
These don't have a lot of memory on them. many early PCs
stored some config info there, but generally the BIOS can
reconstruct it if it isn't there. I suppose there is a
possibility that random data in the CMOS memory could cause
the BIOS to try to use unavailable features and hang. I
don't think anybody put actual executable code in there.
