The development of DOSBox began around the launch of Windows 2000—a Windows NT system [11] —when its creators, [12] Dutch programmers Peter Veenstra and Sjoerd van der Berg, discovered that the operating system had dropped much of its support for DOS software.

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).
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 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.
