I’m testing out some low level boot-time code (think POST beeps) that would be much easier if I could emit beep codes.
Or if there’s a way to blink any of the LEDs, Cryptonomicon-style, that would be cool, too (but harder for me to figure out 
)
I took the motherboard out of the case (mostly) and didn’t see any additional LEDs or speaker leads. The back of the mobo was covered in a plastic film I wasn’t comfortable removing, but I don’t think there’s anything under there.
