FreeDOS

FreeDOS is a complete, free, 100% MS-DOS compatible operating system. Works on old hardware, in DOS emulators, and in embedded systems.

FreeDOS can be used to play classic DOS games, run legacy business software, or develop embedded systems. Any program that works on MS-DOS should also run on FreeDOS.

FreeDOS includes many modern features not found in MS-DOS, or features that are significantly improved from MS-DOS. These features include:
