Video Modes

Standard and Enhanced Video Graphics Array (VGA) modes are available.
Hardware acceleration of graphical user interface (GUI) operations is
provided, and acceleration for 8, 16 and 32-bit pixel depths.
The following table details the standard VGA modes which are currently
implemented in the video BIOS. These modes are supported by standard
BIOS functions. The video BIOS (which is mapped contiguously in the
