2-3-2 About Intel Pentium 4 478-pin CPU

This motherboard provides a 478-pin surface mount, Zero Insertion Force (ZIF) socket,
referred to as the mPGA478B socket supports Intel Pentium 4 processor in the 478 Pin
package utilizes Flip-Chip Pin Grid Array (FC-PGA2) package technology.
The CPU that comes with the motherboard should have a cooling FAN attached to prevent
overheating. If this is not the case, then purchase a correct cooling FAN before you turn on
your system.
WARNING! Be sure that there is sufficient air circulation across the processor's
heatsink and CPU cooling FAN is working correctly, otherwise it may
cause the processor and motherboard overheat and damage, you may install
an auxiliary cooling FAN, if necessary.
To install a CPU, first turn off your system and remove its cover. Locate the ZIF socket and
open it by first pulling the level sideways away from the socket then upward to a 90-degree
angle. Insert the CPU with the correct orientation as shown below. The notched corner
should point toward the end of the level. Because the CPU has a corner pin for two of the
four corners, the CPU will only fit in the orientation as shown.
