BIOS Setup Utility
The BIOS Setup Utility is a hardware configuration program built into your computer’s BIOS (Basic Input/

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
