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¡ G
1. The system is starting for the first time
2. The hardware devices attached to the systems have been
changed
3. 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.
