About FreeDOS
FreeDOS started in 1994, although DOS goes back long before that. Other operating systems used the name "DOS" but we mean disk operating systems compatible with PC DOS, from the original IBM PC in August 1981. DOS and the many applications and games that ran on it remained popular throughout the 1980s and into the 1990s.
Jim Hall started FreeDOS while an undergraduate. He wasn't a fan of Windows 3.x, and when Microsoft announced in 1994 that the next version of Windows would replace DOS entirely, Jim announced a new development effort to create an open source version of DOS.
That project became FreeDOS. Other developers contributed to FreeDOS, adding a command interpreter, kernel, and other tools and utilities. FreeDOS was most popular in the late 1990s and early 2000s, and we have a small but engaged community today.
