DJGPP should support this. Currently, it only supports 256MB of physical memory, the next version of CWSDPMI should support 2GB at least. There's one other requirement: there must be a disk or its close clone, because otherwise I think you will have all kinds of weird problems. > I need fast and straighforward 4GB memory access but with no Virtual > memory This presumably means that you have 4GB of memory installed physically?? Otherwise, how do you access 4GB with no VM?
