2.3 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 informa-
tion.
