CPU Core Speed Derivation Procedure

If CPU Clock
Core/Bus ratio
then CPU core speed

CPU Clock Selection Jumper: SW1

The default hardware configuration for CPU Clock Frequency is set at
100MHz. To use a 133MHz CPU, you need to adjust the CPU clock up to
133MHz by setting the SW1 jumper.
= 100MHz
= 7
= Host Clock x Core/Bus ratio
= 100MHz x 7
= 700MHz
