I just use DOSBOX for running my DOS games and DOS applications. It can emulate different graphics adapters and sound cards. Even the PCJr and Tandy 1000 graphics and sound. FreeDOS is a good replacement of DOS. I remember there was a FreeGEM which lead to OpenGEM: http://www.freedos.org/software/?prog=opengem http://www.freedos.org/software/?prog=opengem OpenGem is based on DRI's GEM GUI for DOS. DRI had DR-DOS and later Open-DOS.
