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.

Auto Mode				Description
J6		JP2		Run the CPU at its specified FSB
				frequency.
				For 66MHz FSB CPUs 66/75/83 MHz can
Short J6		Must be		be selected in the BIOS.
1	2	open	1 2 3	For 100MHz FSB CPUs 100~133MHz can
				be selected in the BIOS.
Note: Don’t put any jumper on JP2 when J6 is set to short.
Manual Mode				Description
J6		JP2		Set power up FSB frequency to 66MHz if
				the user wants to run the CPU at a FSB
Open J6		Short		frequency of 66MHz. Only 66~83MHz
1	2	pin 1-2	1 2 3	FSB can be set in the BIOS.
J6		JP2		Set Power up FSB frequency to 100MHz if
				the user wants to run the CPU at an FSB
				frequency of 100MHz or higher. This
Open J6		Short		setting will allow the user to run the CPU
	2			at a higher FSB frequency, especially when
1		pin 2-3	1 2 3
				the user wants to urn a 66MHz FSB CPU
				at 100MHz and higher FSB frequencies.

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.
