MS-DOS (/ ˌ ɛ m ˌ ɛ s ˈ d ɒ s / em-es-DOSS; acronym for Microsoft Disk Operating System, also known as Microsoft DOS) is an operating system for x86-based personal computers mostly developed by Microsoft.
End-user retail – all versions of IBM PC DOS (and other OEM-adapted versions) were sold to end users. DR-DOS began selling to end users with version 5.0 in July 1990, followed by MS-DOS 5.0 in June 1991; Free download – starting with OpenDOS 7.01 in 1997, followed by FreeDOS alpha 0.05 in 1998 (FreeDOS project was announced in 1994)
Originally MS-DOS was designed to be an operating system that could run on any computer with a 8086-family microprocessor.It competed with other operating systems written for such computers, such as CP/M-86 and UCSD Pascal.
PC DOS remained a rebranded version of MS-DOS until 1993. IBM and Microsoft parted ways—MS-DOS 6 was released in March, and PC DOS 6.1 (separately developed) followed in June. Most of the new features from MS-DOS 6.0 appeared in PC DOS 6.1 including the new boot menu support and the new commands CHOICE, DELTREE, and MOVE.

One makes a bootable floppy disk of the DOS, adds a number of drivers from OS/2, and then creates a special image. The DOS booted this way has full access to the system, but provides its own drivers for hardware.
