BIOS error beeps? about 8088_bios

[ImanolBarba]

For the book8088 BIOS, the whole beeping routine seems to be different to this one.

AFAICT from the book8088 BIOS source code (which as we all know is ripped from this one), it beeps at what is supposed to be 200 Hz according to the source code (feels higher in pitch), once during the 32KB min memory test and then twice if all tests passed.

The timing of the beep function has also been butchered and it seems like it's doubling the delay logic for whatever reason.

In short, on a healthy machine (mine seems to work okay), it goes

BEEP (small pause) BEEP BEEP

I also replicated this on pcem

So it would appear maybe the screen or something in the CGA circuitry is wrong if you're getting no signal IMO

On further examination, I think the CPU is likely to be faulty. I'll order the replacement.

Anyway, I'm still interested in the list of exising "beep" error codes for 8088_bios. :)

Oh, thank you. That's very helpful. :)

Sorry for bothering you with their modifications. I tought they just took the code verbatim and changed the copyright notice.
