Note
The 486SX processor may be soldered onto an adapter
board that is seated in the ZIF socket. Lifting the ZIF
handle releases the adapter board from the socket.
Gently pull the processor chip straight up and set it aside.
Remove the replacement chip from its package and inspect
the pins. If they are bent, do not install the processor chip.
Contact your vendor for a new processor.
Position the processor chip over the socket, as shown below.
Make sure the notched edge of the chip (marked with a
dot) aligns with pin 1 (the extra hole) on the socket. An
arrow traced on the system board identifies pin 1.
Make sure the pins in the processor chip are directly over the
holes in the socket. Then gently push the processor straight
into the socket, pressing evenly on all sides.
If you are installing a 486 processor rather than a Pentium
OverDrive processor, you see an extra row of holes around
the outside of the socket. The 486 chip will not fit into the
outside row of holes.
