CPU SPEED SETUP
The system bus speed can be selectable between 66.6MHz. The user can
select the system bus speed (JP2,JP3,JP4) and change the DIP SWITCH (SW)
selection to set up the CPU speed for 200 - 366MHz processor.
M
The CPU speed must match with the frequency RATIO. It will cause
system hanging up if the frequency RATIO is higher than CPU's.
