Hardware Installation

2-3.4 Jumper Setting

Step 1. Set J6 &JP2 to configure CPU FSB Frequency
If the user wants to use the CPU at its standard FSB (Front Side Bus)
Frequency, J6 has to be closed. This will make sure the system will
provide the CPU with the FSB Frequency it was specified to run at. Make
sure that JP2 is open when using this setting.
If the user wants to run the CPU at another (higher) FSB frequency
however, J6 has to be open. In this case use JP2 to set the FSB frequency.

Note: The "Manual" mode setting facilitates FSB over-clocking. Doing so
will however force your CPU to operate out of its specifications, and
therefore SOYO can not guarantee the proper function of your system.

Description
Run the CPU at its specified FSB
frequency.
For 66MHz FSB CPUs 66/75/83 MHz can
be selected in the BIOS.
For 100MHz FSB CPUs 100~133MHz can
be selected in the BIOS.
Description
Set power up FSB frequency to 66MHz if
the user wants to run the CPU at a FSB
frequency of 66MHz. Only 66~83MHz
FSB can be set in the BIOS.
Set Power up FSB frequency to 100MHz if
the user wants to run the CPU at an FSB
frequency of 100MHz or higher. This
setting will allow the user to run the CPU
at a higher FSB frequency, especially when
the user wants to urn a 66MHz FSB CPU
at 100MHz and higher FSB frequencies.
