Solution:

CPU Installation You can upgrade to a higher power Pentium processor at any time. Simply remove the old CPU, install the new one, and set the jumpers for the new CPU type and speed. I. Installation Instruction 1. Locate the zero insertion force (ZIF) socket-7 for the processor. On the socket and on the processor, identify the pin 1 corner. You can identify the pin 1 corner by noting that in the rectangular matrix of pins and holes on the socket and processor, one pin and one hole is absent on the pin 1 corner. 2. Push the socket locking lever away from the socket to unhook it. Swing the lever into the upright position. 3. Insert the processor into the socket taking care that you have matched the pin 1 corners. No force is required, and the processor should seat smoothly into the socket. 4. Swing the locking lever down and hook it under the latch on the side of the socket to lock it in place. II. Installation Notice 1. Always disconnect the power cord from your chassis before you begin working on it. Do not make connections while the power is on because sensitive electronic components can be damaged by the sudden rush of power. Only experienced electronics person should open the PC chassis. 2. Always ground yourself to remove any static charge before touching the CPU board. Modern electronic devices are very sensitive to static electric charges. Use a grounding wrist strap at all times. Place all electronic components on a static-dissipative surface or in a static-shielded bag when they are not in the chassis. Setting Jumpers The PCI colck setting is controlled by J1 and J2. As you refer to the manual, please note that these 2 jumper must goes with the same time. Pin # 1&2 of J4 is used to choosing P55C (MMX) or P54C CPU. Using any dule power CPU ( with core logic voltage not 3.3V), please choose P55C. Pin # 3 to 6 of J4 is used to controlled the frequency ratio. The Core logic voltage is set
