CPU Bus Ratio Selection (JX1, JX2,JX3, JX4)
The Host Bus speed by the CPU bus ratio equals the CPU’s internal frequency (CPU speed)
If Host Bus speed = 100MHz, CPU bus ratio =4
then CPU speed= 100MHz x 4= 400MHz
please set CPU bus ratio according to the following table.

Note: The most of Socket-370 processors have bus ratio locked. In this case, it’s
not necessary to set the bus ratio by jumper setting. So only unlocked Socket -
370 processors can adjust specified bus ratio through hardware jumper setting.
Warning: Do not set CPU frequency higher than its working frequency. If you do,
we will not be responsible for any damages caused.
