MS-DOS 5.0 came in April 1991, and DR DOS 6.0 was released the following June. [90] These products are collectively referred to as "DOS", even though "Disk Operating System" is a generic term used on other systems unrelated to the x86 and IBM PC. "MS-DOS" can also be a generic reference to DOS on IBM PC compatible computers.
This is the first MS-DOS version Microsoft offered in a shrink wrap packaged product for smaller OEMs or system builders. [264] Apricot Computers pre-announces MS-DOS 4.0, the first multitasking version.

This is a real DOS, like MS-DOS 6.22 or PC DOS 5.00. 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.
So very soon an IBM-compatible architecture became the goal, and before long all 8086-family computers closely emulated IBM hardware, and only a single version of MS-DOS for a fixed hardware platform was all that was needed for the market. This specific version of MS-DOS is the version that is discussed here, as all other versions of MS-DOS ...
86-DOS (a.k.a. QDOS, created 1980), an operating system developed by Seattle Computer Products for its 8086-based S-100 computer kit, heavily inspired by CP/M; Concurrent DOS (a.k.a. CDOS, Concurrent PC DOS and CPCDOS) (since 1983), a CP/M-86 and MS-DOS 2.11 compatible multiuser, multitasking DOS, based on Concurrent CP/M-86 developed by Digital Research
The common usage of MS-DOS unified the x86-based systems, promoting growth of the x86/MS-DOS "ecosystem". As the non-x86 architectures died off, and x86 systems standardized into fully IBM PC compatible clones, a market filled with dozens of different competing systems was reduced to a near-monoculture of x86-based, IBM PC compatible, MS-DOS ...
MS-DOS 7 is a real mode operating system for IBM PC compatibles.Unlike earlier versions of MS-DOS, it was not released separately by Microsoft, [3] but included in the Windows 9x family of operating systems. [4]
