Beep.sys

[Mike Warren]

Does anyone know if the source code to beep.sys was ever made available?
I was told it was in the DDK, but I can't find any mention of it there.

Alternatively, has anyone written a replacement for it? I need a version
that can still be called normally but is silent. If I had the source, I
could just remove the I/O code and recompile.

just disable the beep driver (net stop beep works pre win7), the APIs will
not fail and no sound will be made.

Unfortunately, that doesn't work with ELO touch screens. The ELO driver
causes a BSOD if beep is disabled.

I looked in the wdk, ntddbeep.h is there and it gives you the IOCTL and
device object name definitions you need. you could easily write a KMDF
driver to handle this one IOCTL in under an hour and just do nothing with
the request.
