Is the tone the system sp eaker makes determined by the speaker or by the motherboard?

board.  the speaker is either just a cheap little cone loudspeaker, or a piezo sounder like the one pictured.

 Motherboard,  I believe.   If I recall correctly those silly little speakers are capable of all manner of sounds, though the quality is in keeping with a very small very cheap speaker.. (if as pictured)

Dammit. I just resurrected an old machine and I like the beep it makes better but not enough to swap motherboards between PCs.

I don't like effort.

yep, the classical IBM PC speaker was just connected to a simple tone generator built into one of the interrupt controllers (I think) on the main board. Modern boards just emulate it with something built into the chipset.

edit: BTW, I asked “why” before you explained what you wanted to do.

It might be editable, probably encoded in the firmware somewhere. If you have the PRO version of PC Tools you may  be able to tune it.

It’s the board. They are generally more flexible than you’d think, in the old days it was possible to get computers without sound boards to play some surprisingly complex audio off the PC Speaker.

As long as I can remember pc speakers made the sound that was being sent to them just like a normal speaker. Even in my first pc way back in the late 80s was a Tandy 1000sx and the speaker was a cone like this pic of the insides of a Tandy 1000sx
