pDOSBox

pDOSBox emulates CPU:286/386 realmode/protected mode, DOS-like directory filesystem/XMS/EMS, mouse/joystick and EGA/VGA/VESA graphics system. The DOS o/s being emulated is rather rudimentary, but good enough to launch your favorite DOS applications, and even batch-file-driven DOS applications. You may choose to install other o/s like MSDOS, FreeBSD, Linux, etc on top of the CPU emulator.
