Yup, you are pretty silly :-)

NT is _really_ bad at running DOS programs, especially anything that 
talks directly to the hardware. Some people have reported that the
standard VGA mode 13h does work correctly, and some even claim that
mouse input works using the special NT-compatible mode (this should
be autodetected, but you can force it in the config file to make
sure), but most people can't get the mouse to work, and I don't
think anyone has managed to use SVGA modes.

Solution: use WinAllegro if you want to program for NT. Or switch to 
Linux: DOSEMU does a great job of running djgpp/Allegro programs.
