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).
Mpxplay is a 32-bit console audio player for MS-DOS and Windows. It supports a wide range of audio codecs, playlists, as well as containers for video formats. The MS-DOS version uses a 32-bit DOS extender (DOS/32 Advanced DOS Extender being the most up-to-date version compatible).
It allows the Linux system to load and replace the running DOS without altering existing DOS system files. loadlin and the Linux kernel are both files on a file system accessible to DOS.
