ASUS SP97 / SP97-V User’s Manual 23
III. INSTALLATION
3. Central Processing Unit (CPU)
The motherboard provides a 321-pin ZIF Socket 7 that is backward 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 install a fan
before you turn on your system.
To install a processor, 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
upward 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 toward 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 only one orientation as
shown. The picture is for reference only; the CPU fan must cover the face of the
processor. With the added weight of the fan, no force is required to insert the proces-
sor. Once the processor is 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 processor that you will install.
