3.4.2 Installing Heat-sink Mounting Brackets
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. A
correctly installed bracket can be verified by noting the 4 pins on the top.
These 4 pins should be closest to the Pentium II CPU slot.
2. Insert the heat-sink mount into the holes on the motherboard. When
the bracket is properly inserted into the holes on the motherboard, you will
hear a clicking noise .
3. Lock the heat-sink mount to the board by inserting the two mounting
locks into the pins of the heat-sink mounting bracket which are now below
the motherboard. There will be a click
when the locks are securely
fastened.

3.4.3 Installing Pentium II Passive Processors
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
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 into the module.
3.4.4 Installing Heat-sink Locks
Mounting locks
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.
