Each processor and its associated L-2 cache memory are contained in a Flip Chip Pin Grid Array (FC-PGA) package that is installed in a zero insertion force (ZIF) socket on the system board. The following subsection describes how to install or replace the microprocessor in either the primary or secondary processor connector.
