About the BIOS
The Basic Input/Output System (BIOS) has a setup utility stored in the BIOS memory. The
setup utility reports system information and can be used to configure the BIOS settings. The
configurable data is provided with context-sensitive help and is stored in the system's
battery-backed CMOS RAM. If the configuration stored in the CMOS RAM is invalid, the BIOS
settings return to their default optimal values.
There are seven menus in the BIOS Setup utility, which appear in this order: Main, Advanced,
PCI, Boot, Security, Chipset, and Exit. To navigate the menus or options listed on the menu, use
the arrow keys. The options or fields that you can configure on a menu appear in color. For
instructions on how to navigate and change settings in the BIOS Setup utility, refer to the online
instructions provided on the menu.
