Expansion slots  
In the future, you may need to install expansion cards. The following sub-sections  
describe the slots and the expansion cards that they support.  
Make sure to unplug the power cord before adding or removing expansion  
cards. Failure to do so may cause you physical injury and damage motherboard  
components.  
2.5.1  
Installing an expansion card  
To install an expansion card:  
1.  
2.  
3.  
4.  
Before installing the expansion card, read the documentation that came with  
it and make the necessary hardware settings for the card.  
Remove the system unit cover (if your motherboard is already installed in a  
chassis).  
Remove the bracket opposite the slot that you intend to use. Keep the screw  
for later use.  
Align the card connector with the slot and press firmly until the card is  
completely seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
2.5.2  
Configuring an expansion card  
After installing the expansion card, configure the it by adjusting the software  
settings.  
1.  
Turn on the system and change the necessary BIOS settings, if any. See  
Chapter 4 for information on BIOS setup.  
2.  
3.  
Assign an IRQ to the card. Refer to the tables on the next page.  
Install the software drivers for the expansion card.  
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.

Jumper  
Clear RTC RAM (3-pin 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 onboard button  
cell battery powers the RAM data in CMOS, which include system setup  
information such as system passwords.  
To erase the RTC RAM:  
1. Turn OFF the computer and unplug the power cord.  
2. Remove the onboard battery.  
3. 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.  
4. Reinstall the battery.  
5. Plug the power cord and turn ON the computer.  
6. 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 CLRTC jumper  
default position. Removing the cap will cause system boot failure!

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 the BIOS  
can automatically reset parameter settings to default values.  
Due to the chipset limitation, AC power off is required prior using C.P.R.  
function. You must turn off and on the power supply or unplug and plug the  
power cord before reboot the system.

4.2  
BIOS setup program  
This motherboard supports a programmable Low-Pin Count (LPC) chip that you  
can update using the provided utility described in section “4.1 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 can change the  
configuration of your computer in the future. For example, you can 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 chip.  
The LPC chip 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+Delete>, 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. Being a  
menu-driven program, it lets you 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 “4.8 Exit Menu.”  
•
The BIOS setup screens shown in this section are for reference purposes  
only, and may not exactly match what you see on your screen.
