Though MS-DOS 7.0 and Windows 4.0 could be readily segregated and marketed as different products, Microsoft stopped marketing Windows and MS-DOS separately with the release of Windows 95. [15] A major difference from earlier versions of MS-DOS is the usage of the MSDOS.SYS file. [16] In MS-DOS 7, this is not a binary file, but a
MS-DOS 7.1, LBA/FAT32-enabled DOS component bundled with Windows 98/98 SE in 1998/1999; It may also refer to versions of the IBM PC DOS family: PC DOS 7, successor of PC DOS 6.3 in 1995; PC DOS 2000, successor of PC DOS 7.0 in 1998; PC DOS 7.10, LBA/FAT32-enabled OEM version and successor of PC DOS 2000; It may also refer to versions of the ...
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.
The early versions of Windows ran on top of MS-DOS. At first Windows met with little success, but this was also true for most other companies' efforts as well, for example GEM. After version 3.0, Windows gained market acceptance. Windows 9x used MS-DOS to boot the Windows kernel in protected mode. Basic features related to the file system, such ...
MSDOS.SYS is a system file in MS-DOS and Windows 9x operating systems. In versions of MS-DOS from 1.1x through 6.22, the file comprises the MS-DOS kernel and is responsible for file access and program management. MSDOS.SYS is loaded by the DOS BIOS IO.SYS as part of the boot procedure. [1] In some OEM versions of MS-DOS, the file is named MSDOS ...
Microsoft releases MS-DOS 1.25 (equivalent to PC DOS 1.1; system files are IO.SYS and MSDOS.SYS; GW-BASIC is an entirely disk-based substitute for BASICA). [115] Columbia Data Products introduces the MPC, the first PC clone—which runs MS-DOS 1.25—soon followed by others including Eagle Computer. These machines were not 100% IBM PC compatible.
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
In all 32-bit (IA-32) editions of the Windows NT family since 1993, DOS emulation is provided by way of a virtual DOS machine (NTVDM). 64-bit (IA-64 and x86-64) versions of Windows do not support NTVDM and cannot run 16-bit DOS applications directly; third-party emulators such as DOSbox can be used to run DOS programs on those machines.
