>>>If yours does NOT beep at power-on then I would guess that some tampering with the beep speaker has been done. If it does beep on power-on, then I have no idea why something like "?? chr(7)" doesn't work from the command window (it does here on my speakered machines).

>>If your machine has a sound card then ??CHR(7) comes out of the sound card, not the internal PC speaker. I don't think you can still use the internal speaker (after the POST) when you have a working sound card installed.

>If I turn the speakers off (as I usually do), I don't hear anything. Turning them back on gives me "boom" sound, not a beep. :)


All depends on what .WAV file you've got "Default beep" set to in your Control Panel/Sounds. ;)
