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 <F2> to enter Setup” message is prompted
on the bottom of screen).
Press m to enter setup. Press <F12> during POST to enter multi-boot menu. In this menu, user can change
boot device without entering BIOS SETUP Utility.
