HAPTER BIOS S ETUP TILITY The BIOS (Basic Input and Output System) Setup Utility displays the system's configuration status and provides options to set system parameters. The parameters are stored in battery-backed-up CMOS RAM that saves this informa- tion even when the power is turned off. When the system is turned back on, the system is configured with the values found in CMOS.The following topics are described in this chapter.
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 <Delete>...
