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.
