How to get back the motherboard beeps ?

I could imagine I could access that vxd in some way. [] Rusty gears in memory turning for the first time in decades, so this may not be at all relevant: IIRR, the speaker output, even though a normal loudspeaker (of the sort used in a cheap transistor radio, granted, but capable of at least _some_ fidelity) was used, is only a digital, or at best binary, output; IIRR, the speaker connected between said output and the +5V rail (possibly via a capacitor). As such it could only produce beeps of various frequencies. Or so it seemed initially ... When sound cards were first appearing (and weren't cheap, hard though that may be to believe!), someone (or maybe several someones) devised a driver for the speaker-drive circuit that, by use of pulse-width modulation, could make the speaker drive circuitry behave like a sound card. The quality of the output was pretty atrocious, but just about acceptable for some purposes. The "driver" was I think released as freeware. I _think_ the (software) driver emulated one of the "standard" sound cards available at that time - probably one of the SoundBlaster family. As I said, this may or may not be relevant! -- J. P.
