:
on't the beeps depend on the BIOS? I had steady short beeps once upon and
:time and it was bad RAM. I had used high density RAM in a board that could
:not handle it. Switching the RAM to a regular, low density version solved
:the problem.

Different BIOS have different error/beep codes.
That is a generic list I swiped off the Wikipedia page to show that
the various beeping noises a board might make booting or trying to
boot actually relate to BIOS specific error codes and were not just
random noise.
