Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions).
Phar Lap’s product line was expanded to include 386|VMM, a virtual memory add-in driver, LinkLoc, a linker-locator for embedded development; cross tools for embedded development; and 286|DOS-Extender, a DOS extender that emulated an OS/2 environment, complete with the OS/2 API and protected mode, in contrast with Microsoft's OS/2 API ...
In other words, Phar Lap created an OS/2 compatibility box for DOS. A 16-bit protected-mode DOS application can be built by compiling it with Microsoft C under DOS, specifying that an OS/2 program should be built, and then executing the resulting file on DOS with the aid of 286|DOS-Extender. With Lotus and Microsoft using DOS extenders, an ...
DOS 286 or DOS/286 may refer to: Concurrent DOS 286, a Digital Research CP/M- and DOS-compatible multiuser multitasking operating system variant since 1985; FlexOS 286, a Digital Research FlexOS operating system variant since 1986; OS/2 1.0, an IBM and Microsoft operating system and then-times supposed-to-be successor of MS-DOS/PC DOS since 1987
The Multiuser DOS Federation (MDOS) was an industry alliance to promote the growth and acceptance of multi-user DOS-based solutions on 286, 386 and 486 computers. [1] [2] It was formed in July 1990. [1] Initially among them were Digital Research, Theos Software, SunRiver, DigiBoard, Alloy, Viewport International and others. [2]
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 version included with PC DOS 3.0 and 3.1 is hard-coded to transfer the operating system from A: to B:, while from PC DOS 3.2 onward you can specify the source and destination, and can be used to install DOS to the harddisk. The version included with MS-DOS 4 and PC DOS 4 is no longer a simple command-line utility, but a full-fledged installer.
Multiuser DOS is a real-time multi-user multi-tasking operating system for IBM PC-compatible microcomputers.. An evolution of the older Concurrent CP/M-86, Concurrent DOS and Concurrent DOS 386 operating systems, it was originally developed by Digital Research and acquired and further developed by Novell in 1991.
