holes in the socket. Then gently push the processor straight
into the socket, pressing evenly on all sides.

Pentium OverDrive processor, you’ll see an extra row of
holes around the outside of the socket.
8. Secure the processor by pressing the ZIF handle back to the
closed position.
9. Change the settings of the jumpers so that they are correct
for the type of processor you installed. (Refer to the “CPU
type jumper settings” table.) You may also need to change
the setting of jumper JP6 to match the processor clock
speed.
If you installed a processor with a different voltage
(check the table under “Processor Upgrades” in
Appendix A), you need to change the settings of jumper
JP1 on the voltage regulator. See the tables under
“Changing the Jumper Settings” for information on all
processor jumper settings.
10. If you are upgrading to a DX DX2, DX4, or Pentium
OverDrive processor, you must also install a heat sink over
the processor. Follow the instructions included with the
heat sink.
11. Replace any option cards you removed; see “Installing an
Option Card” for instructions.
12. Replace the computer’s cover as described under “Replacing
the Cover.” Then see “Post-installation Procedures” for
instructions on configuring your computer with your new
processor.
