    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. 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.
