III.INSTALLATION

3.Central Processing Unit (CPU)

The TXP4 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.
