Actually, I'm wondering how those things work. Do they read the POST
code off the motherboard, or do they do their own diagnosis? I've
looked at the ads in various magazines, but never thought it had
much potential.
It's called POST, the last time I bought a POST board it was 59$ and
that was 3 years ago. it displays a two digit code that points to the
failed subsystem.
IBM systems also displayed a code to the CRT (if working) that also
told
the problem.
Generally I've troubleshot PCs with nothing more than a VOM. Frequently
less.
