Are you saying that the DJGPP programs worked at first, but now they don't? You cannot use CWSDPMI on an NT, because NT won't let CWSDPMI to load. CWSDPMI needs to switch the CPU into protected mode, but NT already runs in protected mode and will refuse to switch. You need to understand why does the NT DOS box refuse to load DJGPP programs. Forget CWSDPMI; the reason is elsewhere. Somehow you configured your system so that it disables DPMI services to DOS programs. Maybe the property sheets of the DOS box have some settings (like the amount of DPMI memory) which disables this. > Well I downloaded the DPMI program anyway and put it in my bin > directory.

AFAIK, there are no drivers there except CWSDPMI (which you don't need). > One would suspect that reboot would reset whatever got changed > but no. Changes that you do to the registry or to the properties of the DOS box are not undone when you reboot.
