Bochs VBE Extensions

The Bochs VGA BIOS supports, to an extend, the VBE specification. Since Bochs only emulates a VGA card down to the hardware level (and a Cirrus graphics card if you enable it, but that is not tied in with the Bochs VBE extensions), it emulates very simple graphics hardware that the VBE BIOS can drive. The advantage of this is that if you are running your OS in Bochs (or Qemu, which uses the Bochs VGA BIOS), you can use this emulated hardware to directly set video modes, without using VBE (which would require real mode or v86).
