Accelerator Adapter

Your monitor and the SVGA adapter can coexist with either a monochrome
adapter and a monochrome monitor or a color graphics adapter and an RGB
color monitor.

The SVGA adapter is always the primary video display adapter. It is the
default display adapter on startup and reset.

Notes:

* The SVGA adapter is limited to modes that do not conflict with the modes
  of the other video adapter. Select your modes with this in mind.

  IBM-compatible computers allow only one video adapter to be mapped as
  monochrome and one to be mapped as color. Therefore, if you use the SVGA
  adapter with a monochrome adapter and monochrome monitor, use only
  color-mapped modes. Monochrome VGA modes, Hercules graphics, and MDA modes
  will not be available on the SVGA adapter.

  If you have a color graphics adapter and an RGB monitor, use only
  monochrome-mapped modes on the SVGA adapter. Color modes will not be
  available on the SVGA adapter.

* Use the MS-DOS mode command to switch between the two video adapters. Even
  though you have two video adapters, set the main logic board switches (PCs,
  XTs, and compatibles) or run the setup utility (ATs or compatibles) as if
  you were installing a VGA adapter of "EGA type."
* The SVGA adapter cannot be used with an EGA adapter or another VGA adapter
  of any type.
