System Utilities
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 F2 during POST (when “Press  to enter Setup” message is prompted 
on the bottom of screen).
Press F2 to enter setup. The default parameter of F12 Boot Menu is set to “disabled”. If you want to change 
boot device without entering BIOS Setup Utility, please set the parameter to “enabled”. 
Press  during POST to enter multi-boot menu. In this menu, user can change boot device without 
entering BIOS SETUP Utility.
Navigating the BIOS Utility
There are six menu options: Information, Main, Advanced, Security, Boot, and Exit.
Follow these instructions:
•To choose a menu, use the left and right arrow keys.
•To choose an item, use the up and down arrow keys.
•To change the value of a parameter, press F5 or F6.
•A plus sign (+) indicates the item has sub-items. Press Enter to expand this item.
•Press Esc while you are in any of the menu options to go to the Exit menu.
•In any menu, you can load default settings by pressing F9. You can also press F10 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. Please 
note that system information is subject to different models.
