III. INSTALLATION

3. Central Processing Unit (CPU)

The motherboard provides a 321-pin ZIF Socket 7 that is backwards compatible

with ZIF Socket 5 processors. The CPU that came with the motherboard should

have a fan attached to it to prevent overheating. If this is not the case then purchase

a fan before you turn on your system. Apply thermal jelly to the CPU top and then

install the fan onto the CPU.

WARNING: Without a fan circulating air on the CPU and heat sinks, the

CPU and/or heat sinks can overheat and cause damage to both the CPU and the

motherboard. (See "CPU Cooling Fan Connector” at the end of this section.)

To install a CPU, first turn off your system and remove its cover. Locate the ZIF

socket and open it by first pulling the lever sideways away from the socket then

upwards to a 90-degree right angle. Insert the CPU with the correct orientation as

shown. Use the notched corner of the CPU with the white dot as your guide. The

white dot should point towards the end the of the lever. Notice that there is a blank

area where one hole is missing from that corner of the square array of pin holes and

a "1" printed on the motherboard next to that corner. Because the CPU has a corner

pin for three of the four corners, the CPU will only fit in the one orientation as

shown. The picture is for reference only; you should have a CPU fan that will cover

the face of the CPU. With the added weight of the CPU fan, no force is required to

insert the CPU. Once completely inserted, hold down on the fan and close the

socket's lever.

IMPORTANT: You must set jumpers for "CPU to BUS Frequency Ratio" and

jumpers for "BUS Frequency Selection" depending on the CPU that you install.
