B. Boxed Pentium
The Boxed Pentium
has a Heat Sink Support. So if you're going to use a Boxed Pentium
Processor, all you need is the Retention Mechanism.
Step 1: Insert the Retention Mechanism Attach Mount at the bottom
of the mainboard.
Step 2: Install the Retention Mechanism.
Look for the key on Slot 1, and match it with the Notch Key on the
Retention Mechanism for proper direction. Then, attach the
Retention Mechanism to the Retention Mechanism Attach Mount.
Use a Screwdriver to secure the Retention Mechanism.
