2.5 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.
2.5.1 Installing an expansion card
To install an expansion card:
1. Before installing the expansion card, read the documentation that came with
it and make the necessary hardware settings for the card.
2. Remove the system unit cover (if your motherboard is already installed in a
chassis).
3. Remove the bracket opposite the slot that you intend to use. Keep the screw
for later use.
4. Align the card connector with the slot and press rmly until the card is
completely seated on the slot.
5. Secure the card to the chassis with the screw you removed earlier.
6. Replace the system cover.
2.5.2 Conguring an expansion card
After installing the expansion card, congure 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. Assign an IRQ to the card. Refer to the tables on the next page.
3. Install the software drivers for the expansion card.
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

2.6 Jumper
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 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!
• Make sure to re-enter your previous BIOS settings after you clear the
CMOS.
• 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.

4.2 BIOS setup program
This motherboard supports a programmable rmware 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, reconguring
your system, or prompted to“Run Setup.” This section explains how to congure
your system using this utility.
Even if you are not prompted to use the Setup program, you can change the
conguration 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 recongure your system using the BIOS Setup program so that the
computer can recognize these changes and record them in the CMOS RAM of the
SPI chip.
The rmware 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, reboot the system by doing any of the
following procedures:
• Restart using the OS standard shut-down procedure.
• Press <Ctrl>+<Alt>+<Del> simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys to force
reset from a running operating system can cause damage to your data or
system. We recommend to always shut-down the system properly from the
operating system.
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.
