Chapter 2 System Utilities About the Setup Utility The computer uses the latest Award BIOS with support for Windows Plug and Play. The CMOS chip on the main board contains the ROM setup instructions for configuring the main board BIOS. 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.
Entering the Setup Utility When you power on the system, BIOS enters the Power-On Self-Test (POST) routines. POST is a series of built-in diagnostics performed by the BIOS. After the POST routines are completed, the following message appears: Press DEL to enter SETUP Press the delete key to have access to the BIOS Setup Utility. NOTE: If the message disappears before you respond and you still want to enter Setup, restart the system by turning it OFF and On.
