Hello,
This message is for the developers.
I noticed that your driver (VDMSound) works under
DPMI (protected mode) applications. I am currently
writing a VDD, but am having trouble using the Dispatch
() and other calls (you know, the C4 C4 58 xx opcodes
that the VDM catches) inside PMODE. It works fine in
real mode.

I am interested in how you were able to do this.. do you
actually use the Dispatch or do you rely on catching
IN/OUT operations while in protected mode.

Thank you so much for your assistance!

-Jon

    IN/OUT ops. Dispatch is only used to load/configure the VDD.
