Well I hope I entertained someone by this...

I misread/misunderstood you.

I thought you wanted a DPMI server which didn't implement 0c00h, 0c01h.
I got the impression that the ones that you have (like CWSDPMI) didn't
do what you wanted, thus they DID implement those calls (this is where
I went awry).


Now I see that you're in the client position and want to to code a TSR
in a DPMI 0.9 environment.

Sorry for any confusion I've caused.


Then it's not that simple. One way might be to add those support for
functions 0x0c00 and 0x0c01 to CWSDPMI.
