Onboard LEDOnboard LEDOnboard LEDOnboard LEDOnboard LED

The motherboard comes with a standby power LED that lights up toindicate that the system is ON, in sleep mode, or in soft-off mode.This is a reminder that you should shut down the system and unplug

the power cable before removing or plugging in any motherboardcomponent. The illustration below shows the location of the onboardLED.

1.4 Before you proceed

Take note of the following precautions before you install motherboardcomponents 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 toa metal object, such as the power supply case, before handlingcomponents 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 groundedantistatic pad or in the bag that came with the component.

Before you insta l l o r remove any component , ensureBefore you insta l l o r remove any component , ensureBefore you insta l l o r remove any component , ensureBefore you insta l l o r remove any component , ensureBefore you insta l l o r remove any component , ensurethat the ATX power supp ly i s sw i tched of f o r thethat the ATX power supp ly i s sw i tched of f o r thethat the ATX power supp ly i s sw i tched of f o r thethat the ATX power supp ly i s sw i tched of f o r thethat the ATX power supp ly i s sw i tched of f o r thepower cord i s detached f rom the power supp ly .power cord i s detached f rom the power supp ly .power cord i s detached f rom the power supp ly .power cord i s detached f rom the power supp ly .powe r cor d is deta ched from the p ower supp ly.

To install a CPU:

1. Locate the CPU socket on the motherboard.

1.6 Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed forthe Intel Pentium 4 processor in the 775-land package.

Your boxed Intel Pentium 4 LGA775 processor package shouldcome with installation instructions for the CPU, fan and heatsinkassembly. If the instructions in this section do not match the CPUdocumentation, follow the latter.

Upon purchase of the motherboard, make sure that the PnP cap ison the socket and the socket pins are not bent. Contact yourretailer immediately if the PnP cap is missing, or if you see anydamage to the PnP cap/socket pins/motherboard components.ASUS will shoulder the cost of repair only if the damage is shipment/transit-related.

Keep the cap after installing the motherboard. ASUS will processReturn Merchandise Authorization (RMA) requests only if themotherboard comes with the cap on the LGA775 socket.

The product warranty does not cover damage to the socket pinsresulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.

Before installing the CPU, make sure that the socket box is facingtowards you and the load lever is on your left.

3. Lift the load lever in the directionof the arrow to a 135 angle.

4. Lift the load plate with yourthumb and forefinger to a 100angle (A), then push the PnP capfrom the load plate window toremove (B).

To prevent damage to the socket pins, do not remove the PnP capunless you are installing a CPU.

5. Position the CPU over thesocket, making sure thatthe gold triangle is onthe bottom-left corner ofthe socket. The socketalignment key should fitinto the CPU notch.

2. Press the load lever with your thumb (A) and move it to the left (B)until it is released from the retention tab.

This motherboard supports Intel Pentium 4 CPUs in the 775-landpackage with Hyper-Threading Technology.

Hyper-Threading Technology is supported under Windows XP/2003Server and Linux 1.7.x (kernel) and later versions only. Under Linux,use the Hyper-Threading compiler to compile the code. If you areusing any other operating systems, disable the Hyper-ThreadingTechnology item in the BIOS to ensure system stability andperformance.

Installing Windows XP Service Pack 1 or later is recommended.

Make sure to enable the Hyper-Threading Technology item in BIOSbefore installing a supported operating system.

For more information on Hyper-Threading Technology, visitwww.intel.com/info/hyperthreading.

To use the Hyper-Threading Technology on this motherboard:

1. Install an Intel Pentium 4 CPU in the 775-land package that supportsHyper-Threading Technology.

2. Power up the system and enter the BIOS Setup (see Chapter 2: BIOSsetup). Under the Advanced Menu, make sure that the itemHyper-Threading Technology is set to Enabled. The item appears onlyif you installed a CPU that supports Hyper-Threading Technology.

The Intel Pentium 4 LGA775 processor requires a specially designedheatsink and fan assembly to ensure optimum thermal condition and

performance.

Install the motherboard to the chassis before you install the CPU fanand heatsink assembly

When you buy a boxed Intel Pentium 4 processor, the packageincludes the CPU fan and heatsink assembly. If you buy a CPUseparately, make sure that you use only Intel-certifiedmulti-directional heatsink and fan.

Your Intel Pentium 4 LGA775 heatsink and fan assembly comes in

a push-pin design and requires no tool to install.

If you purchased a separate CPU heatsink and fan assembly, make surethat a Thermal Interface Material is properly applied to the CPU heatsinkor CPU before you install the heatsink and fan assembly.

To install the CPU heatsink and fan:

1. Place the heatsink on top of the

installed CPU, making sure thatthe four fasteners match theholes on the motherboard.

1.8.11.8.11.8.11.8.11.8.1 Installing an expansion cardInstalling an expansion cardInstalling an expansion cardInstalling an expansion cardInstalling an expansion card

To install an expansion card:

1. Before installing the expansion card, read the documentation thatcame with it and make the necessary hardware settings for the card.

2. Remove the system unit cover (if your motherboard is alreadyinstalled in a chassis).

3. Remove the bracket opposite the slot that you intend to use. Keepthe screw for later use.

4. Align the card connector with the slot and press firmly until the card iscompletely seated on the slot.

5. Secure the card to the chassis with the screw you removed earlier.

6. Replace the system cover.

1.8.21.8.21.8.21.8.21.8.2 Configuring an expansion cardConfiguring an expansion cardConfiguring an expansion cardConfiguring an expansion cardConfiguring an expansion cardAfter installing the expansion card, configure it by adjusting the softwaresettings.

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.

Make sure to unplug the power cord before adding or removingexpansion cards. Failure to do so may cause you physical injury anddamage motherboard components.

This jumper allows you to clear the Real Time Clock (RTC) RAM inCMOS. You can clear the CMOS memory of date, time, and systemsetup parameters by erasing the CMOS RTC RAM data. The onboardbutton cell battery powers the RAM data in CMOS, which includesystem 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 2-3 (default) to pins 1-2. Keep thecap on pins 1-2 for about 5~10 seconds, then move the cap back topins 2-3.

4. Re-install the battery.

5. Plug the power cord and turn ON the computer.

6. Hold down the key during the boot process and enter BIOSsetup to re-enter data.

Except when clearing the RTC RAM, never remove the cap on CLRTCjumper default position. Removing the cap will cause system boot failure!

You do not need to clear the RTC when the system hangs due tooverclocking. For system failure due to overclocking, use the C.P.R. (CPUParameter Recall) feature. Shut down and reboot the system so the BIOScan automatically reset parameter settings to default values.
