CPU SPEED SETUP

The system bus speed can be selectable between 66.6MHz and 100MHz. The user can select the system bus speed (JP8) and change the DIP SWITCH selection to set up the CPU speed for 233 - 633MHz processor.

MThe CPU speed must match with the frequency RATIO. It will cause system hanging up if the frequency RATIO is higher than CPU's.

	FREQ. RATIO		DIP SWITCH
		1	2	3	4
	X 3	ON	OFF	ON	ON
	X 3.5	OFF	OFF	ON	ON
	X 4	ON	ON	OFF	ON
