Processor Socket

The processor installs in a 370-pin Socket 370 on the system board. The
processor is held in place in the socket by a locking lever attached to the socket
and a removable retention clip. The retention clip anchors both the processor
and the processor heatsink to the Socket 370.
To remove or install a processor, see Section 3, "Disassembly and Reassembly."
