Graphics Controller

The graphics controller is specifically designed for graphics-intensive
operations, including 3-D and 2-D effects, texture mapping, text and color pixel
amplification, and video acceleration. The controller minimizes bus traffic by
off-loading the tasks normally performed by the processor, providing 64-bit,
high resolution performance for demanding True Color displays and other
sophisticated graphics functions.

Motion Video Controller

The motion video controller integrates a Windows graphical user interface
(GUI) engine and motion video playback hardware.
Support includes:
T
MPEG-1 or MPEG-2
T
Video for Windows
T
Active Movie (Windows 95 and Windows 98).
MPEG is a compression/decompression standard developed by a professional
video group called the Motion Picture Experts Group. MPEG produces full-
screen, 30-frames-per-second (fps), broadcast-quality digital video.

Graphics Support

Depending on the graphics board, the system supports the following resolutions,
colors, and refresh rates for systems with 4 MB or 8 MB of video memory (see
