DOSBox is a free and open-source emulator which runs software for MS-DOS compatible disk operating systems—primarily video games. [5] It was first released in 2002, when DOS technology was becoming obsolete. Its adoption for running DOS games is widespread, with it being used in commercial re-releases of those games as well.
The SELECT command formats a disk and installs country-specific information and keyboard codes. It was initially only available with IBM PC DOS. 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 ...

While the OS/2 1.x DOS box was based on DOS 3.0, OS/2 2.x MVDMs emulate DOS 5.0. [1] Seamless integration of Windows 3.1 and later Win32s applications in OS/2 is a concept looking similar on surface to the seamless integration of XP Mode based on Windows Virtual PC in Windows 7. A redirector in a "guest" VDM or NTVDM allows access on the disks ...
It was released as an extension to LibreOffice before code was merged into LibreOffice 4.2.3.3 main code in 2014. [ 3 ] The lightweight implementation (1,400 lines in Python-PyUNO) uses the embedded Python to give a simplified programming interface to the vector graphics of LibreOffice for graphic design and education (including teaching of ...
The first DPMI specification drafts were published in 1989 by Microsoft's Ralph Lipe. [4] [1] While based on a prototypical version of DPMI for Windows 3.0 in 386 enhanced mode, several features of this implementation were removed from the official specification, including a feature named MS-DOS Extensions [5] or DOS API translation that had been proposed by Ralph Lipe in the original drafts. [6]
It uses a combination of hardware-assisted virtualization features and high-level emulation.It can thus achieve nearly native speed for 8086-compatible DOS operating systems and applications on x86 compatible processors, and for DOS Protected Mode Interface (DPMI) applications on x86 compatible processors as well as on x86-64 processors.
The original DOS API in 86-DOS and MS-DOS 1.0 was designed to be functionally compatible with CP/M.Files were accessed using file control blocks (FCBs). The DOS API was greatly extended in MS-DOS 2.0 with several Unix concepts, including file access using file handles, hierarchical directories and device I/O control. [1]
