2.1 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.  
Onboard LED  
The motherboard comes with a standby power LED. The green LED lights  
up to indicate 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 motherboard component.  
The illustration below shows the location of the onboard LED.

2.2 Motherboard overview  
Before you install the motherboard, study the configuration of your chassis  
to ensure that the motherboard fits into it.  
Make sure to unplug the power cord before installing or removing the  
motherboard. Failure to do so can cause you physical injury and damage  
motherboard components.  
2.2.1 Placement direction  
When installing the motherboard, make sure that you place it into the  
chassis in the correct orientation. The edge with external ports goes to the  
rear part of the chassis as indicated in the image below.  
2.2.2 Screw holes  
Place seven (7) screws into the holes indicated by circles to secure the  
motherboard to the chassis.  
Do not overtighten the screws! Doing so can damage the motherboard.  
Place this side towards  
the rear of the chassis

2.3 Central Processing Unit (CPU)  
The motherboard comes with a surface mount LGA775 socket designed for  
the Intel® Pentium® 4 processor in the 775-land package  
Upon purchase of the motherboard, make sure that the PnP cap is  
on the socket and the socket contacts are not bent. Contact your  
retailer immediately if the PnP cap is missing, or if you see any  
damage to the PnP cap/socket contacts/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 process  
Return Merchandise Authorization (RMA) requests only if the  
motherboard comes with the cap on the LGA775 socket.  
The product warranty does not cover damage to the socket  
contacts resulting from incorrect CPU installation/removal, or  
misplacement/loss/incorrect removal of the PnP cap.  
2.3.1 Installing the CPU  
To install a CPU:  
1. Locate the CPU socket on the motherboard.
