1.2.4 Graphics Array

The graphics array is located on the system board and operates in two

video modes:

1. VGA compatibility mode

2. XGA compatibility mode.

The system comes with at least four video-memory modules (512KB)

installed. Four additional sockets are available for installing

additional video-memory modules (maximum video memory is 1MB). When the

system is powered-on, the graphics array is in the VGA mode. In this

mode, all VGA alphanumeric text, and all-points-addressable (APA) graphics

video modes are supported. The maximum resolution in VGA compatibility

mode is 720-by-400 picture elements (PELS) in the text mode, and

640-by-480 PELS in the graphics mode. A maximum of 256 colors or 64

shades of gray is supported in VGA mode. Composite video is not

supported.

The graphics array is in the XGA mode only when enabled by the DOS Adapter

Interface or video device driver (example: MS Windows, OS/2 Presentation

Manager device drivers).

The XGA works with monochrome and color-analog direct-drive displays.

XGA supports the following:

+------------------------------------------------------------------------+

¦ System Board Video ¦ Resolution ¦ Colors ¦

¦ Memory ¦ ¦ ¦

+-----------------------+------------------------+-----------------------¦

¦ Four video modules ¦ 640 x 480 ¦ 256 16 ¦

¦ installed (512KB) ¦ or ¦ ¦

¦ ¦ 1024 x 768 ¦ ¦

+-----------------------+------------------------+-----------------------¦

¦ Eight video modules ¦ 640 x 480 ¦ 256 ¦

¦ installed (1MB) ¦ ¦ ¦

+------------------------------------------------------------------------+

The system board has a dedicated 32-bit expansion slot for video adapter

cards. This slot (J3) includes the auxiliary video connector (AVC) and

connects the VGA compatible video from the XGA (on the system board) to

video adapters (example: IBM PS/2 Image Adapter/A - 1MB).
