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 ...
MS-DOS Editor uses a text user interface and its color scheme can be adjusted. It has a multiple-document interface in which its version 2.0 (as included in DOS 7 or Windows 9x) can open up to 9 files at a time while earlier versions (included in DOS 5 and 6) are limited to only one file.
It was initially developed by Microsoft for Windows 3.0, although Microsoft later turned control of the specification over to an industry committee with open membership. [ 1 ] [ 2 ] Almost all modern DOS extenders are based on DPMI and allow DOS programs to address all memory available in the PC and to run in protected mode (mostly in ring 3 ...
[26] [27] DOSBox is designed for legacy gaming (e.g. King's Quest, Doom) on modern operating systems. [17] [26] DOSBox includes its own implementation of DOS which is strongly tied to the emulator and cannot run on real hardware, but can also boot MS-DOS, FreeDOS, or other DOS operating systems if needed.
FreeDOS is designed to work well with virtualization software such as VirtualBox and VMware. The installation process is identical to real hardware. It is also possible to install FreeDOS on DOSBox and its derivatives. By doing so, it provides additional functionality not present in the emulator. [43] [44]
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).

Bochs emulates the hardware needed by PC operating systems, including hard drives, CD drives, and floppy drives. It doesn't utilize any host CPU virtualization features, therefore is slower than most virtualization (as opposed to emulation) software.
