8-10 Installation and Troubleshooting Guide
-''
To take advantage of future options in speed and functionality, you can add a second
processor or replace either the primary or secondary processor.
!"!
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.
In addition to the ZIF socket for the primary microprocessor on the system board,
there is a second ZIF socket to accommodate a secondary microprocessor. The sec-
ondary microprocessor must have the same operating frequency as the primary
microprocessor.
The following items are included in the microprocessor upgrade kit:
A microprocessor chip
A heat sink
A securing clip
A voltage regulator module (VRM), if adding a second processor
