Accelerator Adapter

Mode 3 (80-column text) is the default video mode of the SVGA adapter. In
addition to the default, the adapter supports the following classes of video
modes:

* Other standard VGA modes, EGA modes, and MCGA modes--Provide resolutions
  of up to 640 x 480.
* Super VGA modes--Provide even higher resolutions and the ability to
  display more colors simultaneously. Super VGA can also display text 132
  columns wide and 25, 28, 44, or 50 lines deep.
* CGA, Hercules, and MDA modes--Required by applications designed to run
  under earlier video standards (CGA, Hercules, and MDA). For example, to
  run Hercules-compatible software and some CGA-compatible games, you must
  use a Hercules or CGA mode. When in a CGA, a Hercules, or an MDA mode, the
  adapter emulates the earlier video standard.

The following tables list the supported video modes and resolutions
available under each video standard. Following the tables are instructions
for using VGAMODE.EXE to switch video modes.
