comply with limits for a Class B digital device,
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 accordance with the instructions, may cause
harmful interference to radio communications.
However, there is no guarantee that interference
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 the equipment 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.
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 accept any interference received, including interference
that may cause undesired operation.

CPU Speed Setup
The system bus speed is selectable at 100,133MHz. The user can select the system bus speed
(SW1 & JP25) and change the DIP switch (SW2) selection to set up the CPU speed for 500 –
1GHz + processor.

«
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 38 for more information).
Line In: In general, Line In is normally Line In.
When you select “Four Speaker” in Creative
application(see page 36 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.
