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.
NOTE: This mode is AMD platform. Please refer to an actual sample or finish good unit for real system 
information.
