Er i c Lu

pursuant to Part 15 of the FCC rules. These
limits are designed to provide reasonable
protection against harmful interference in
residential installations. This equipment
generates, uses, and can radiate radio
frequency energy, and if not installed and used
in accord ance with the instr uctions, may cause
harmful interference to radio communications.
However, there is no guara nte e tha t i nterfer ence
will not occur in a particular installation. If this
equipment does cause interference to radio or

television equipment reception, which can be
determined by turning th e equi pment off and on, the user i s encour aged to try t o
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.

This device complies with Part 15 of the FCC Rules. Operation is subjected to
the following two conditions 1) this device may not cause harmful interference
and 2) this device must a ccept any interference received , in cl uding interference
that may cause undesired operation.

Frequency Multiple.

For double CPU use, the same CPU must b e used in CPU so cket1 and 2. (T he same

stepping, FSB, ratio)

For single CPU use, use CPU socket1 only. Don’t use CPU socket2.

Note: We don’t recommend you to set up your system speed to 112 , 124 , 142 ,152 MHz



because these frequencies are not the standard specifications for CPU, Chipset and
most of the peripherals. Whether your system can run under 112 ,124 ,142 ,152 MHz
properly will depend on your hardware configurations: CPU, 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 45 for more information).
Line In: In general, Line In is normally Line In.
When you select “Four Speaker” in Creative
application(see page 43 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
