2.4 Running the BIOS Setup Program
Your panel PC is likely to have been properly set up and configured by
your dealer prior to delivery. You may still find it necessary to use the
panel PC's BIOS (Basic Input-Output System) setup program to
change system configuration information, such as the current date and
time or your type of hard drive. The setup program is stored in
read-only memory (ROM). It can be accessed either when you turn on
or reset the panel PC, by pressing the "Del" key on your keyboard
immediately after powering on the computer.
The settings you specify with the setup program are recorded in a
special area of memory called CMOS RAM. This memory is backed up
by a battery so that it will not be erased when you turn off or reset the
system. Whenever you turn on the power, 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 will be displayed on screen, and you will be
prompted to run the setup program.
If you want to change the setup of BIOS, refer to Chapter 9 for more
detailed information.
