The motherboard comes with a standby power LED that 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.
1.4 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.

Installling the CPU
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 for
the Intel
®
Pentium
®
4 processor in the 775-land package.
•
Your boxed Intel
®
Pentium
®
4 LGA775 processor package should
come with installation instructions for the CPU, fan and heatsink
assembly. If the instructions in this section do not match the CPU
documentation, follow the latter.
• Upon purchase of the motherboard, make sure that the PnP cap is
on the socket and the socket pins are not bent. Contact your
retailer immediately if the PnP cap is missing, or if you see any
damage 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 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 pins
resulting from incorrect CPU installation/removal, or misplacement/
loss/incorrect removal of the PnP cap.
•
The motherboard does not support Enhanced Intel SpeedStep
technology, C1E and TM2 technology.
Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.
