This section explains how to use the UEFI SETUP UTILITY to configure 
your system. The UEFI chip on the motherboard stores the UEFI SETUP 
UTILITY. You may run the UEFI SETUP UTILITY when you start up the 
computer. Please press <F2> or <Del> during the Power-On-Self-Test 
(POST) to enter the UEFI SETUP UTILITY, otherawise, POST will continue 
with its test routines.
If you wish to enter the UEFI SETUP UTILITY after POST, restart the sys-
tem by pressing <Ctl> + <Alt> + <Delete>, or by pressing the reset button 
on the system chassis. You may also restart by turning the system off and 
then back on.

following UEFI setup screens and descriptions are for reference 
purpose only, and they may not exactly match what you see on 
your screen.
