Chapter 231 BIOS Setup Utility The BIOS Setup Utility is a hardware configuration program built into your computer’s BIOS (Basic Input/ Output System). Your computer is already properly configured and optimized, and you do not need to run this utility. However, if you encounter configuration problems, you may need to run Setup. Please also refer to Chapter 4 Troubleshooting when problem arises. To activate the BIOS Utility, press m during POST (when “Press to enter Setup” message is prompted on the bottom of screen). Press m to enter setup. Press during POST to enter multi-boot menu. In this menu, user can change boot device without entering BIOS SETUP Utility.

32Chapter 2 Navigating the BIOS Utility There are six menu options: Info., Main, System Devices, Security, Boot, and Exit. Follow these instructions: TTo choose a menu, use the cursor left/right keys (zx). TTo choose a parameter, use the cursor up/down keys ( wy). TTo change the value of a parameter, press por q. TA plus sign (+) indicates the item has sub-items. Press e to expand this item. TPress ^ while you are in any of the menu options to go to the Exit menu. TIn any menu, you can load default settings by pressing t. You can also press u to save any changes made and exit the BIOS Setup Utility. NOTE: You can change the value of a parameter if it is enclosed in square brackets. Navigation keys for a particular menu are shown on the bottom of the screen. Help for parameters are found in the Item Specific Help part of the screen. Read this carefully when making changes to parameter values. This menu provides you the information of the system.
