2.4.2 CPU installation Follow these steps to install a CPU. 1. Locate the 478-pin ZIF socket on the motherboard. 2. Unlock the socket by pressing the lever sideways, then lift it up to a 90°-100° angle. Socket Lever Make sure that the socket lever is lifted up to 90°-100° angle, otherwise the CPU does not fit in completely. 3. Position the CPU above the socket such that its marked corner matches the base of the socket lever. 4. Carefully insert the CPU into the socket until it fits in place. The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU! 5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked. 90 - 100 Gold Mark 2-6 Chapter 2: Hardware setup
