4.1About BIOS Settings

This section describes how to view and modify the BIOS settings.

The BIOS has a Setup utility stored in the BIOS flash memory. The Setup utility reports system information and can be used to configure the BIOS settings. The configured 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 will default to the original state specified at the factory.

4.1.1Navigating BIOS Screens

The BIOS Setup utility contains seven menu screens, which are displayed in this order: Main, Advanced, PCI/PnP, Boot, Security, Chipset, and Exit. See Appendix B for a BIOS menu tree and illustrations of the screens.

Use the left and right arrow keys to move sequentially through the seven BIOS screens. Fields that can be reconfigured are displayed in color. All other fields are non-configurable. Use the up and down arrow keys to scroll through a screen's menu. Use the Tab key to move across columns.
