Electronic Emission Notices
Federal Communications Commission (FCC) Statement (02852C)
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment
generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with instructions contained in this manual, may cause harmful interference
to radio and television communications. However, there is no guarantee that interference
will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television 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 RELOCA TE THE RECEIVING ANTENNA
- INCREASE THE SEP ARATION BETWEEN THE EQUIPMENT AND THE RECEIVER
- CONNECT THE EQUIPMENT INTO AN OUTLET ON A CIRCUIT DIFFERENT FROM
THA T OF THE RECEIVER
- CONSUL T THE DEALER OR AN EXPERIENCED AUDIO/TELEVISION TECHNICIAN
NOTE: Connecting this device to peripheral devices that do not comply with Class B
requirements, or using an unshielded peripheral data cable, could also result in
harmful interference to radio or television reception.
The user is cautioned that any changes or modifications not expressly approved
by the party responsible for compliance could void the user’s authority to operate
this equipment.
To ensure that the use of this product does not contribute to interference, it is

Hardware Configuration
Motherboard Layout
The following diagrams show the relative positions of the jumpers, connectors, major
components and memory banks on the motherboard.
NOTE 1) Be sure to check the cable orientation in order to match the colored strip to the pin
1 end of the connector.
2) When you start up the system, please wait for 5 seconds after you power on AC.
#
If you are using standard ATX power supply (without P4 12V power
connector), you MUST connect a peripheral power plug (the plug
supplying power to HDD / CDROM) into J16. Thus you can use either
ATX 12V power supply or standard ATX power supply for this motherboard
(Noted : NOT all kinds of standard ATX power supply are guaranteed to be
applicable in this motherboard.).

Jumper Settings
This chapter explains how to configure the motherboard’s hardware. Before using your
computer, make sure all jumpers and DRAM modules are set correctly. Refer to this
chapter whenever in doubt.
CPU Speed Selection
In this motherboard, jumperless feature is implemented such that no jumper is required to
be set for different type of CPU installed.
Notice:
1. Be sure to save the CMOS setting when exit the CMOS.
2. The CPU is frequency multiplier locked, no CPU speed change will be seen
even if the frequency multiplier setting in CMOS setup is changed.
