%description
    Bochs is a highly portable open source IA-32 (x86) PC emulator
    that runs on most popular platforms. It includes emulation of
    the Intel x86 CPU, common I/O devices, and a custom BIOS. Bochs
    can be compiled to emulate a 386, 486 or Pentium CPU. It can
    then run most Operating Systems inside the emulation including
    Linux, Windows, DOS, and others. This package also contains a
    pre-configured FreeDOS 8h1 image to demonstrate Bochs in action.
