2.2.2. Running the BIOS Setup

If you are a commercial user, the LIBRA system should have been properly set up and configured by your dealer. You may still find it necessary to change the system configuration information. In this case, you need to run the system’s BIOS setup program.

Under the following conditions, the CMOS settings are to be changed.

1.The system is starting for the first time.

2.The hardware devices attached to the LIBRA III system 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.

To change the BIOS setup, please refer to Chapter 7 for more information.
