DOS

This article is about an operating system. For the original series, see Commercial games#Original PC series. For the version history of Doom, see Versions of Doom and Doom II.

DOS is a family of operating systems for IBM PC–compatible computers, primarily consisting of IBM PC DOS and a rebranded version, Microsoft's MS-DOS, both released in 1981. MS-DOS, after licensing to IBM, was also licensed to several dozen IBM PC–compatible manufacturers, becoming the primary DOS operating system. Later compatible systems from other manufacturers include DR-DOS, ROM-DOS, PTS-DOS, and FreeDOS. DOS was id Software's primary platform for all releases from Commander Keen in Invasion of the Vorticons to Quake II.

Doom was originally released for DOS by id Software in 1993. The last Doom binaries were released for id Anthology in 1996, which included several fixes to Final Doom maps and engine bugs. The Unity port and Doom + Doom II releases included DOSBox with the DOS version of Doom.

The released Doom source code is for Linux Doom, not the DOS version. It could not be released due to copyright issues concerning the DMX sound library. When Raven Software released the source code of Heretic and Hexen the DMX sound library was not included, though some 'dangling' calls are intact. The 2023 Doom source code leak does include source code for the DOS version of Doom.

There are several modern projects seeking DOS, particularly MS-DOS, compatibility. These include: FreeDOS, a GPL DOS operating system, which started in 1994 after Microsoft announced that it was abandoning development and support for MS-DOS; and DOSBox, a DOS emulator, which started in 2002 and has been included in several re-releases of Doom engine games.

FreeDOS, on several installation media includes Freedoom, which is bundled with SMMU (since 1.1), as well as Boom, as a secondary source port (since 1.3).
