Beep frequency

Does anybody know which registry key stores the default tone (frequency) of the system beep in windows nt 4?

Is it possible to change it?

Normally the frequency of the beep is fixed as the speaker in intel machines is pretty basic and can only beep at a particular frequency.  The only way to change it is to add a sound card and then use the 'Sounds' applet in the Control Panel to alter the WAV file used for particular events.  I did once find a sound driver for a PC speaker, but that was on a Win3.x PC many moons ago.

There's no way to do this under Win NT.
Utilities existed under Win 3.x, 9x and DOS, but these accessed hardware directly, which is something NT does not support.
