3.4.2 Installation: Heat-sink Mounting Bracket
1. The Heat-sink mount has two pins on the bottom and 4 pins on the top.
Notice that the bottom two pins are of different sizes. The size of the pins
and the holes in the motherboard will determine the correct orientation.
When the bracket is correctly installed, these 4 pins should be on the top
and closest to the Pentium II CPU slot.

the bracket is properly inserted into the holes on the motherboard, you will
hear a clicking noise .

3.4.3: Installation of the Pentium II Passive Processor
1. Align the CPU with the CPU Retention Module. Make sure the Heat-
sink is lined up with the Heat-sink mount bracket. If you put the CPU in
the wrong way, you may damage the CPU, the motherboard, and/or the
CPU socket.
2. Slowly press down on the CPU module until the CPU locks into place.
A clicking noise will be heard when the CPU is locked securely.
3.4.4: Installation of the Heat-sink Lock
The Heat-sink lock has 4 notches which will correspond to the 4 pins on
the Heat-sink mounting bracket. Gently slide the lock between the Heat-
sink onto the Heat-sink Mounting Bracket until both sides of the lock are
firmly secured. A clicking sound will be heard when the lock is securely
fastened to the heat-sink mounting bracket. To remove the lock from the
Heat-sink mounting bracket, gently press the ends of the locks inward and
pull.
