mode, and not powered OFF. Unplug the power cable from the power outlet
and make sure that the standby power LED is OFF before installing any
system component.
• Use a grounded wrist strap or touch a safely grounded object or
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.

2.4 Central Processing Unit (CPU)
2.4.1 Overview
The motherboard comes with a surface mount LGA775 socket designed for
the Intel®Pentium®4 processor in the 775-land package.
• Check your motherboard to make sure that the PnP cap is on the
CPU 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.
2.4.3 Installing CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.
2.4.2 Removing the storage drive assembly
1. Lay the system on its side, then locate and remove three storage drive
assembly screws.
2. Lift the storage drive assembly, then set aside.
