Or a working speaker, in most cases. POST will only tell you what the
BIOS maker wants to tell you, though. Using debug mode (aka ICE mode)
from a debug port would allow you to diagnose at a much
deeper level. If
you couple that with a logic analyzer, you can diagnose just about
any
problem, of course, but the built-in debug capablity that the Pentium
gives you was the best I had seen from any microprocessor last I checked.
You could do a *very* cool front-panel on a modern PC.
