JJ,

Oh... Does it beep under pure DOS?

Didn't think of that myself, good one.

Yes, when I do an INT 10h, AX=0E07h the beeper sounds

In case there's a DOS device driver interfering with the speaker.

.... Which doesn't sound in a Windows console window.

It really looks to me its a Windows software problem (of sorts), not BIOS.
But than again, the fact that some direct I/O fiddling under Windows also
sounded the beeper pretty-much already told me that.

Regards,
Rudy Wieser
