Removing the CPU.
To remove the CPU, move the locks to the center of the CPU. A click will be
heard when the CPU has been unlocked. Gently pull up on the CPU, taking care
not to bend the motherboard or the CPU retention module.
To remove the lock from the retention module, gently press the ends of the locks
inward and pull.
Installing SECC2 CPUs - Option 1
The major physical difference between regular Pentium II’s and Pentium SECC2 is
the plastic CPU enclosure. As Figure 2-12 indicates, the plastic CPU enclosure
covers the entire CPU card of regular Pentium II’s. On the other hand, the plastic
CPU enclosure covers only the side faces of the SECC2 Pentium II / III card.
Due to the physical differences in the SECC2 CPU, installing the retention
modules requires a different technique than the ones previously discussed.
