Upgrading the i486 CPU module
The CPU module is equipped with a Pentium OverDrive Ready ZIF socket. The socket is capable of
supporting faster i486 CPUs and OverDrive CPUs (including future 3.3 V dc CPU technology).
To install a higher performance CPU:
1) Remove the CPU module.
2) Place the CPU module on an anti-static surface.
3) Lift up on the lever to release the CPU.
4) Remove the CPU noting its pin 1 location.
NOTE
When installing a faster i486 CPU, make sure to align it with the outside row of pins
visible.
5) Install the new CPU. Make sure pin 1 on the CPU is aligned with pin 1 on the ZIF socket. Pin 1 is
located at the notched end of the CPU (A, Figure 3 - 20).
6) Return the release lever to its original position.
7) Set any appropriate jumpers.
8) Install and secure the CPU module to the main logic board.
