Your computer’s system board should not bend under
the insertion pressure.  If it bends more than slightly,  or
if you have difficulity in correctly seating the Pentium
OverDrive processor, see your dealer for assistance or
refer to the section 
Getting Help, page 28.

Ensure that the motherboard in your system has sufficient support to allow
you to apply the pressure necessary to seat your Pentium OverDrive proces-
sor.  It is important that you do not bend the motherboard during the seating
process. If necessary, you can place reinforcement such as a pad of paper
underneath the socket area. Be sure to remove the reinforcement before
turning your computer back on.

As you press firmly, you should be able to feel the Pentium OverDrive
processor slide into place.  When the Pentium OverDrive processor is fully
inserted, the pins are barely visible, and there is a slight  gap between the
Pentium OverDrive processor and the socket. The gap should be even  around
each side of the Pentium OverDrive processor, and about the same thickness
as the chip removal tool.

If you have difficulty in seating the Pentium OverDrive processor, you may
find it necessary to remove the processor fan in order to apply pressure to the
center of the chip. For information on removing and replacing the fan, refer
to the section Troubleshooting, page 27.

Proceed to Step 6.
