CPU Core Speed Derivation Procedure
If CPU Clock = 100MHz
Core/Bus ratio = 7
then CPU core speed = Host Clock x Core/Bus ratio
= 100MHz x 7
= 700MHz
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.
