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 monitor or a compatible, multifrequency
monitor that uses 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, you need to install the appropriate drivers if you
want to use resolutions over 640 x 480 or to take advantage of
these special features when using certain application programs:
Enhanced graphic and text modes in 4,16, and 256 colors
Resolutions up to 1024 x 768
Extended text mode for 80-column text in 30, 43, and 60
rows and 132-column text with 25, 30, 43, and 60 rows.
Your computer comes with 512KB of video memory installed
on the system board. You can upgrade the video memory to
1MB by installing additional video memory chips, allowing you
to use higher resolutions in more colors. See Chapter 3 for
installation instructions.
