Note

If the microprocessor in your system is a PQFP type, it is surface-mounted on the main system board. This means that if you install an OverDrive processor, you can install it in the empty OverDrive socket. In this case, you need to disable the original microprocessor by moving jumper J23 to position

2-3. You also need to make sure the jumper settings for Jl0, Jll, and J12 are set correctly.

Processor speed jumper settings

You need to change the processor speed jumper settings only if you replace a 25 MHz processor with a 33 MHz processor.
