1.6 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.

1. 6. 1 In st al li ng an e xp ans io n ca rd

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.

1. 6. 2 Co nf ig ur in g a n ex pan si on c ar d

After installing the expansion card, congure it by adjusting the software

settings.

1. Turn on the system and change the necessary BIOS settings, if any.
See Chapter 2 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.

1. Clea r R T C R A M ( C LRT C )
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.

2.2 BIOS setup program

This motherboard supports a programmable rmware 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,

reconguring your system, or prompted to“Run Setup.” This section
explains how to congure your system using this utility.

Even if you are not prompted to use the Setup program, you can change

the conguration 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 recongure 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:

• Re s t a r t usi n g t he OS s t a ndar d s h ut-do w n p roce d u r e .

• Pr e s s < Ctrl > + < A l t>+< D e l > simu l t a n eous l y .

• Pr e s s t he r e s e t butt o n o n th e s y stem c h a s sis.

• Pr e s s t he p o w e r butt o n t o tu r n t he sy s t e m off t h e n bac k o n .

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.

• 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 Setup
Defaults item under the Exit Menu. See section “2.8 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.

• Visit the ASUS website (www.asus.com) to download the latest BIOS

le for this motherboard.
