dbDOS VM Virtual Machine (dbDOS VM); The dbDOS VM or VM stands for Virtual Machine and with dbDOS it is a DOS emulation that allows products developed for DOS-based applications to run inside the virtual machine. The VM supports the Windows Operating Systems (XP, 2003, Vista, 2008, 7, 8, 8.1) in either 32- or 64-bit editions.
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).
A member of the series, Windows XP, debuted on October 25, 2001, and became the first consumer-oriented version of Windows to not use DOS. Although Windows XP could emulate DOS, it could not run many of its applications as they ran only in real mode to directly access the computer's hardware, and Windows XP's protected mode prevented such ...
SetVer is a TSR program designed to return a different value to the version of DOS that is running. This allows programs that look for a specific version of DOS to run under a different DOS. The command is available in MS-DOS versions 5 and later. [1]
COMMAND.COM is the default command-line interpreter for MS-DOS, Windows 95, Windows 98 and Windows Me.In the case of DOS, it is the default user interface as well. [2] It has an additional role as the usual first program run after boot (init process), hence being responsible for setting up the system by running the AUTOEXEC.BAT configuration file, and being the ancestor of all processes.
On Linux, it is possible to run DOSEMU, a Linux-native virtual machine for running DOS programs at near native speed. There are a number of other emulators for running DOS on various versions of Unix and Microsoft Windows such as DOSBox. [26] [27] DOSBox is designed for legacy gaming (e.g. King's Quest, Doom) on modern operating systems.
Many 16-bit Windows legacy programs can run without changes on newer 32-bit editions of Windows. The reason designers made this possible was to allow software developers time to remedy their software during the industry transition from Windows 3.1x to Windows 95 and later, without restricting the ability for the operating system to be upgraded to a current version before all programs used by a ...
The program is a recompilation of 4OS2, and continues to have features of OS/2's command processor (cmd.exe), such as running REXX scripts, and EXTPROC support. A corresponding Take Command/32 exists for this, version 1 corresponding to 4NT 2.5. 4NT and Take Command/32 were released in both ANSI (Windows 9x) and Unicode (Windows NT) forms, with ...
