Is DPMI going to allow me to access linear memory? Yes. > 2. How do I tell CWSDPMI the memory area that belongs to this card (so I can > stop GPF'ing)? See section 18.7 of the DJGPP FAQ list, it explains how to do that and presents a skeleton code. make sure you have the latest CWSDPMI release r5, since older versions had subtle bugs in the related functionality. > 3. Do I need a device driver for my hardware? If all you need is to move data, no driver is required.
