Before you proceed
Take note of the following precautions before you install motherboard
components or change any motherboard settings.
• Unplug the power cord from the wall socket before touching any
component.
• Use a grounded wrist strap or touch a safely grounded object or
to a metal object, such as the power supply case, before handling
components to avoid damaging them due to static electricity
• Hold components by the edges to avoid touching the ICs on them.
• Whenever you uninstall any component, place it on a grounded
antistatic pad or in the bag that came with the component.
• Before you install or remove any component, ensure
that the ATX power supply is switched off or the power
cord is detached from the power supply. Failure to do so
may cause severe damage to the motherboard, peripherals, and/or
components.

When using PCI cards on shared slots, ensure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments. Otherwise,
conflicts will arise between the two PCI groups, making the system
unstable and the card inoperable.

Jumpers
1. Clear RTC RAM (CLRTC)
This jumper allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system
setup parameters by erasing the CMOS RTC RAM data. The RAM data
in CMOS, that include system setup information such as system words,
is powered by the onboard button cell battery.
To erase the RTC RAM:
1.
Turn OFF the computer and unplug the power cord.
2.
Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the
cap on pins 2-3 for about 5~10 seconds, then move the cap back
to pins 1-2.
3.
Plug the power cord and turn ON the computer.
4.
Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
Except when clearing the RTC RAM, never remove the cap on the jumper
default position. Removing the cap will cause system boot failure!

Clear RTC
You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R.
(CPU Parameter Recall) feature. Shut down and reboot the system so
BIOS can automatically reset parameter settings to its previous values.

Set these jumpers to +5V to wake up the computer from S1 sleep
mode (CPU stopped, DRAM refreshed, system running in low power
mode) using the connected USB devices. Set to +5VSB to wake up
from S3 and S4 sleep modes (no power to CPU, DRAM in slow refresh,
power supply in reduced power mode).
+5VSB
• The USB device wake-up feature requires a power supply that can provide 500mA on the +5VSB lead for each USB port. Otherwise, the system would not power up.
• The total current consumed must NOT exceed the power supply capability (+5VSB) whether under normal condition or in sleep mode.

BIOS Setup program
This motherboard supports a programmable LPC chip that you can update
using the provided utility described in section “2.1 Managing and updating
your BIOS.”
Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to “Run Setup”. This section
explains how to configure your system using this utility.
Even if you are not prompted to use the Setup program, you may want to
change the configuration of your computer in the future. For example, you
may want to enable the security password feature or change the power
management settings. This requires you to reconfigure your system using
the BIOS Setup program so that the computer can recognize these changes
and record them in the CMOS RAM of the LPC.
The LPC on the motherboard stores the Setup utility. When you start up
the computer, the system provides you with the opportunity to run this
program. Press <Del> during the Power-On Self Test (POST) to enter the
Setup utility. Otherwise, POST continues with its test routines.
If you wish to enter Setup after POST, restart the system by pressing <Ctrl>+<Alt>+<Del>, or by pressing the reset button on the system
chassis. You can also restart by turning the system off and then back on.
Do this last option only if the first two failed.
The Setup program is designed to make it as easy to use as possible. It is
a menu-driven program, which means you can scroll through the various
sub-menus and make your selections from the available options using the
navigation keys.
The default BIOS settings for this motherboard apply for most conditions
to ensure optimum performance. If the system becomes unstable after
changing any BIOS settings, load the default settings to ensure system
compatibility and stability. Select the Load Default Settings item under
the Exit Menu. See section “2.8 Exit Menu.”
The BIOS setup screens shown in this chapter are for reference purposes
only, and may not exactly match what you see on your screen.
