Installing a Pentium II Processor

See Figure 4-7.

1. Observe the warnings and cautions on page 3, “Safety Guidelines.”

2. Remove the left side cover (page 80).

3. Being careful not to touch the components or gold edge connectors on

the processor module, remove it from its protective wrapper and place
it heat-sink side down on a nonconductive, static-free surface.

4. Record the module serial number in your equipment log.

5. Press the locking tabs inward until they remain retracted.

6. Hold the module by its top edge or upper corners, and firmly press it

into the connector (Figure 4-7) on the system board. Press the locking
tabs outward so they engage the support bracket.
