CPU Speed Setup
The system bus frequency can be switched between 66MHz and 133MHz by adjusting JP17 &
JP10. The CPU Frequency is control by BIOS.
M The CPU speed must match with the frequency RATIO. It will cause system hanging up
if the frequency RATIO is higher than that of CPU.

« Note: Please set the CPU host frequency in accordance with your processor’s
specifications. We don’t recommend you to set the system bus frequency over
the CPU’s specification because these specific bus frequencies are not the
standard specifications for CPU, chipset and most of the peripherals. Whether
your system can run under these specific bus frequencies properly will depend
on your hardware configurations, including CPU, Chipsets, SDRAM,
Cards….etc.
« Note: JP17 is only available when the mother board use 82810E chipset.
