Environmental Safety Instruction
z Avoid the dusty, humidity and temperature extremes. Do not place the product in
any area where it may become wet.
z 0 to 60 centigrade is the suitable temperature. (The figure differs from the request
of the main chipset)
z Generally speaking, dramatic changes in temperature may lead to contact
malfunction and crackles due to constant thermal expansion and contraction from
the welding spots’ that connect components and PCB. Computer should go
through an adaptive phase before it boots when it is moved from a cold
environment to a warmer one to avoid condensation phenomenon. These water
drops attached on PCB or the surface of the components can bring about
phenomena as minor as computer instability resulted from corrosion and oxidation
from components and PCB or as major as short circuit that can burn the
components. Suggest starting the computer until the temperature goes up.
z The increasing temperature of the capacitor may decrease the life of computer.
Using the close case may decrease the life of other device because the higher
temperature in the inner of the case.
z Attention to the heat sink when you over-clocking. The higher temperature may
decrease the life of the device and burned the capacitor.

Environmental Protection Announcement
Do not dispose this electronic device into the trash while discarding. To minimize

Introducing BIOS
Notice!
The BIOS options in this manual are for reference only. Different
configurations may lead to difference in BIOS screen and BIOS
screens in manuals are usually the first BIOS version when the board is
released and may be different from your purchased motherboard.
Users are welcome to download the latest BIOS version form our
official website.
The BIOS is a program located on a Flash Memory on the motherboard. This program
is a bridge between motherboard and operating system. When you start the computer,
the BIOS program will gain control. The BIOS first operates an auto-diagnostic test
called POST (power on self test) for all the necessary hardware, it detects the entire
hardware device and configures the parameters of the hardware synchronization.
Only when these tasks are completed done it gives up control of the computer to
operating system (OS). Since the BIOS is the only channel for hardware and software
to communicate, it is the key factor for system stability, and in ensuring that your
system performance as its best.
3-1 Entering Setup
Power on the computer and by pressing <Del> immediately allows you to enter Setup.
If the message disappears before your respond and you still wish to enter Setup,
restart the system to try again by turning it OFF then ON or pressing the “RESET”
button on the system case. You may also restart by simultaneously pressing <Ctrl>,
<Alt> and <Delete> keys. If you do not press the keys at the correct time and the
system does not boot, an error message will be displayed and you will again be asked
to
Press <Del> to enter Setup
