6. Position the processor chip over the socket, aligning the
notched edge of the chip (marked with a dot) with pin 1 on
the socket, as shown below.
Caution
If you install the processor chip in the wrong orientation,
you may damage the chip and void your warranty.
7. Make sure the pins in the processor chip are directly over the
holes in the socket. Then gently push the microprocessor
straight into the socket, pressing evenly on all sides.
If you are installing a 486 chip rather than a Pentium
OverDrive processor, you’ll see an extra row of holes
around the outside of the socket. The 486 chip does not
occupy the outside row of holes.
8. Secure the processor chip by pressing the ZIF handle back to
the closed position.
