Upgrading the 560 / 566 CPU module.
The 560/566 CPU module is equipped with a ZIF socket (Socket 4 type) capable of supporting Intel
OverDrive CPUs.
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 release lever to release the CPU.
4) Remove the CPU, noting its pin 1 orientation.
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, Figure3 - 23).
6) Return the release lever to its original position.
7)
Set any appropriate jumpers.
Refer to the following section entitled “560/566 CPU Module Jumper
Locations”.
8) Install and secure the CPU module to the main logic board.
NOTE
Earlier versions of the CPU module did not have a voltage regulator card (66 MHz
version) as shown in A, Figure 3 - 22 or a jumper card (60 MHz version). Also, the
heat sinks on the CPU may vary from this figure.
