7.1. Award BIOS
The Award BIOS ROM builds in a setup program, which
allows the users to modify the basic system configuration
such as the current date and time or the type of
peripheral devices attached to the computer.
Under the following conditions, the CMOS settings are to
be changed;
4. The system is starting for the first time
5. The hardware devices attached to the systems have
been changed
6. The CMOS memory has lost power and the
configuration information has been erased.
The BIOS setup program is stored in ROM, which can be
accessed by pressing <DEL> key on the keyboard
immediately when the system is powered on.
In order to retain the specified setup information when
the system power is turned off, the system setup
information is stored in a battery-backed CMOS RAM.
The battery is to ensure the settings will not be erased
when the computer is turned off or reset. When the
computer is powered on again, the system will read the
settings stored in the CMOS RAM and compare them to
the equipment check conducted during the power on self
test (POST). If any error or mismatch occurs, an error
message will be shown on the screen and the computer
will be prompted to run the setup program.
