products may also support 1280 x 1024 x 16 and 1024 x

To take advantage of these enhancements, your computer
includes software support for several popular application
programs. The following sections describe the procedures
necessary to install these programs so they can take full
advantage of your computer’s enhanced capabilities.
To obtain the external monitor display drivers, you must
use the Maintenance and Backup procedures defined in
Chapter 1 to make a VGA diskette. You must then install
the drivers from the diskette into your /UTILS directory.
This is done by typing A:\INSTALL.
The TravelMate 4000M drivers described in this chapter
assume you are using a color VGA configuration. If you are
using a monochrome VGA monitor, use the
VGA.EXE utility
to switch from monochrome VGA mapping to color mapping
before using the drivers. The command VGA VGA will set
your computer to color mapping.
