Installing CPU Retention Modules
Installation of a Pentium II processor requires a CPU retention module, which
is first secured onto the motherboard.
To attach the retention module, place the motherboard on a flat surface. Locate
the key pin on one end of the Pentium II slot on the board. Then carefully line
up the key notch on the
retention module with the key
pin on the Pentium II slot (the
key pin on the Pentium II slot
indicates the correct
orientation of the CPU).
Drop the retention module
(Figure 14 on the following
page) down over the Pentium
II slot so that the retention
module sits flat against the
motherboard. Tighten the
screws in a clockwise manner
to secure the module to the
board. Warning: Do not
overtighten the screws as you
may damage the module and/or the motherboard.
Installing the Active Processor
When the retention module is securely installed, you are ready to plug in the
CPU. Press down firmly on the CPU until you hear a “click” (see Figure 15 ). This
