television equipment reception, which can be
determinedbyturningtheequipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna
-Move the equipment away from the receiver
-Plug the equipment into an outlet on a circuit different from that to which
the receiver is connected
-Consult the dealer or an experienced radio/television technician for
additional suggestions
You are cautioned that any change or modifications to the equipment not
expressly approve by the party responsible for compliance could void Your
authority to operate such equipment.

CPU Speed Setup
The system bus frequency can be switched at 66MHz, 100MHz, 133MHz and Auto by adjusting
JP10/JP11/JP25 (See Figure 1). 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.

Auto Configuration:
Figure 1
Ö If the CPU FSB is 133 FSB, the frequency of the SDRAM can be determined by
SDRAM’s SPD or setting in BIOS.
M If JP10, JP11, JP25 is not present, FSB will be determined automatically. If these 3
jumpers are available, you can choose at 66MHz, 100MHz, 133MHz and Auto.
M 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.

Line Out 1: Line Out or SPDIF (The SPDIF output is
capable of providing digital audio to external speakers
or compressed AC3 data to an external Dolby digital
decoder). In general, Line Out 1 is normally Line Out,
when it output digital signal, it will be change to SPDIF
Out automatically (see page 49 for more information).
Line In: In general, Line In is normally Line In. When
you select “Four Speaker” in Creative application
(see page 47 for more information), Line In will be
change to Line Out 2, then you can plug 2 pairs stereo
speaker into Line Out 1 and Line In simultaneously.
