2.1 A Quick Tour of the TREK-520 Computing box.
Before starting to set up the Computing Box, take a moment to become familiar with the
locations and purposes of the controls, drives, connectors and ports, which are illustrated
in the figures below. When the Computer box is placed inside truck glove cabinet or under
the passenger’s seat next to the driver, its front appears as shown in Figure 2.1.

2.3 Running the BIOS Setup Program
In most cases, the computer will have been properly set up and configured
by the dealer or SI prior to delivery. However, it may still be necessary to
adjust some of the computer's BIOS (Basic Input-Output System) setup
programs to change the system configuration data, like the current date and
time, or the specific type of hard drive currently installed.
The setup program is stored in read-only memory (ROM). It can be accessed
either when turning on or resetting the computer, by pressing the “Del” key on
the keyboard immediately after powering up the computer.
The settings that are specified with the setup program are recorded in a
special area of the memory called CMOS RAM. This memory is backed up by
a battery so that it will not be erased when turning off or resetting the system.
Whenever the power is turned on, the system reads the settings stored in
CMOS RAM and compares them to the equipment check conducted during the
“power on self-test” (POST). If an error occurs, an error message is displayed
on screen, and the user is prompted to run the setup program.
