device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reason-
able 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 the instructions, may cause harmful interference to radio communica-
tions. 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 re-
ception, which can be determined by turning the equipment off and on, the user is encour-
aged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment onto an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Shielded interconnect cables and shielded AC power cable must be employed with this
equipment to insure compliance with the pertinent RF emission limits governing this
device. Changes or modifications not expressly approved by the system’s manufacturer
could void the user’s authority to operate the equipment.

motherboard. Has information on performance optimi-
zation and troubleshooting.
Chapter 7: Technical Information
Lists the motherboard’s technical specifications.
Manual Features
This User’s Manual is intended to be useful and informa-
tive while also making it easy to quickly find specific
information or specifications. The manual has icons and
notes in the sidebar to note important topics, indicate
warnings or further explain and illustrate key points. We
suggest that most users review the manual to become
familiar with the motherboard. Expert users may want to
review topics selectively, as needed.
If The Motherboard Is Already Installed
You may receive the motherboard installed in a working
system. If this is the case, you should still probably re-
view the sections on configuring and using the board,
especially if an Operating System is not installed yet.
If You Need To Install This Motherboard
We recommend that only experienced users and techni-
cians install this motherboard. If you don’t feel confident
about installing this product, we suggest having a quali-
fied computer technician install and configure the sys-
tem. This service is usually provided at a reasonable fee
by better computer stores and service companies.
