About BIOS, Basic Input and Output System

The BIOS setup utility displays the system's configuration status and provides you with options to set system parameters. The parameters are stored in battery backed up CMOS RAM that saves this information when the power is turned off. When the system is turned back on the system is configured with the value you stored in CMOS.

 A standard configuration has already been set in the setup utility. The setup utility should be used when:

 - changing the system configuration

- a configuration error detected and you are prompted to make changes to the setup utility

- trying to resolve IRQ conflicts

- making changes to the Power management configuration.

- changing the password or making other changes to the Security Setup.
