Follow these steps to install the second Pentium CPU:
1. Turn off the system and unplug the power cable from the wall socket.
2. Detach the Pentium CPU board from the system board.
3. Detach the heat sink by removing the clip and the four screws securing it
to the CPU board. (You do not need to remove the fan from the heat
sink.)
4. Locate the second CPU socket and plug-in the new CPU.
NOTE:
5. Re-attach the heat sink to the board with the four screws and the clip.
6. Re-install the CPU board to the system board.
7. Reconnect the cables.
8. Reconfigure the system using the EISA Configuration Utility (ECU).
Refer to Chapter 6 for details.
Read the electrostatic discharge (ESD) precautions in
Chapter 1 before unpacking and installing the upgrade
CPU.
Make sure that pin 1 of the CPU corresponds to pin 1
of the socket. Insert the CPU pins into the socket
pinholes gently but firmly. Be careful not to bend any
pins.
