Questions tagged [disk-operating-system]

Disk Operating System (DOS) was the first operating system by Microsoft that dominated the IBM PC compatible market between 1981 and 1995. Do not use this tag for questions about DOSBox, FreeDOS or any later operating system from Microsoft.

  • DR-DOS (Digital Research Corporation)
  • FreeDOS (free and open source): http://www.freedos.org/
  • IBM PC-DOS (IBM)
  • MS-DOS (Microsoft)
