If not are there any __dpmi_ functions that i can use to setup No. V1.x doesn't support it under DPMI environments (ie windows, etc) either > or do I have to code this all fro scratch. Perhaps someone has coded such > a page fault handler and would like to share his code with others ?:) It would be virtually impossible to provide this sort of access under a DPMI 0.9 host. This could be done with a DPMI 1.0 host - but the only one out there is currently 386MAX. The source for CWSDPMI is available, so you could add some custom extension to it for this purpose.
