If you use a chip puller, position the puller between the
processor chip and the socket.
You can also use a small, flat-edged screwdriver instead of a
chip puller. Carefully wedge the tip of the screwdriver
between the processor chip and the socket. Gently turn the
screwdriver until the chip begins to separate from the
socket. Move the screwdriver to another side of the
processor chip and again turn it until the chip separates
from the socket. Keep doing this until you can lift the
processor chip straight up from the socket.
Caution
The 486SW 25 microprocessor may be soldered onto an
adapter board that is seated in the microprocessor
socket. Make sure you position your chip puller or
screwdriver just above the socket to avoid damaging the
adapter board.

Gently pull the processor chip straight up and set it aside.
5.
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 microprocessor.
