NTVDM is a special virtual environment/machine to make old DOS = programs run=20 under Windows. Unfortunately, it's broken in several ways starting with = Windows=20 2000. It gets worse in Vista, where must-have graphics modes for those = old DOS=20 programs are optional to implement. Finally, none of 16-bit DOS and = 32-bit Dos=20 Protected Mode Interface applications won't work under any 64-bit = Windows as-is.=20 You will have to install some virtualization software like VMWare, = Virtual=20 Server/PC, Bochs, QEMU, etc, create a virtual PC with a virtual HDD in = it,=20 install DOS in it and run all your DOS apps in there. The only = more-or-less=20 guaranteed way. Sigh.

I can't use makefile and have problems with keyboard and graphics = commands.

I had used it before under plain DOS and some of my old programs = don't=20 work

in a DOS-box under XP.

So sometimes I have to boot DOS from disk and use DJGPP from = there.

So, it works from DOS and from a DOS-box, but AFAIR there had = been some=20 problems,
