Chapter 5

Installing Video Drivers

The Utility diskettes included with your system contain enhanced VGA (video graphics array) drivers and utilities for your computer’s built-in VGA adapter. This chapter describes how to install and use these drivers and utilities.

Your computer’s built-in VGA adapter is compatible with IBM VGA. The drivers and utilities described in this chapter work with any VGA and compatible, multifrequency monitors that use analog input.

Standard VGA monitors display resolutions up to 640 x 480, and you do not need to install the drivers or utilities for your system to operate properly with your application programs at this resolution.

However, if you want to use resolutions over 640 x 480 or take advantage of the following special features when using certain application programs, you need to install the appropriate drivers:

UEnhanced graphic and text modes in 4, 16, and 256 colors Cl Resolutions up to 1024 x 768

Ll Extended text mode for 132-column text with 25, 30, 43, and

60rows.

Your computer comes with 256KB of video memory installed on the system board. You can upgrade the video memory to either 512KB or 1MB by installing additional video memory chips, allowing you to use higher resolutions and more colors. See Chapter 3 for installation instructions.
