This manual is provided “As-Is” with no warranties of any kind, expressed or implied, including, but not limited to the
implied warranties or conditions of this product’s fitness for any particular purpose. In no event shall we be liable for any

WARNING: CMOS Battery Damage
Replace your system’s CMOS RAM battery only with the identical CR-2032 3V Lithium-Ion coin cell (or equivalent) battery
type to avoid risk of personal injury or physical damage to your equipment. Improper installation might cause battery to
explode. Always dispose of used batteries according to the manufacturer’s instructions, or as required by the local
ordinance (where applicable). The damage due to not following this warning will void your motherboard’s manufacturer
warranty.
Perchlorate Material- Special Handling May Apply.

Additional Information:
Additional information on setting this board up can be found in the User’s Manual in the provided CD or DVD ROM. The
Online User’s Manual and FAQ/Knowledge Base can be found on our website by visiting our website:
http://www.bcmcom.com. If your question is not answered in our FAQ/Knowledge Base, visit our forums and post your
messages or submit a new FAQ through FAQ Submittal form for us to add your question in our FAQ with our answer.
ATTENTION: Incorrect BIOS Setup
If you do not know how to handle BIOS setup or how to set it up properly, it is strongly advisable that you do not modify
any of the settings than otherwise instructed in the User’s Quick Start Card. Even a seemingly small incorrect adjustment
or modification in the BIOS setup can render your system unstable or unusable. Incorrect BIOS setup is not covered by
your motherboard’s manufacturer warranty. Try Clear CMOS information when system does not boot after BIOS settings
change.
Motherboard Layout:
WARNING: Electrostatic Sensitive Device (ESD)
Static electricity can easily damage your motherboard and will void your motherboard warranty. Keep the motherboard
and other system components in their anti-static packaging until you are ready to install them. Touch a grounded surface
before you remove any system component from its protective anti-static packaging. Unpacking and installation should be
done on a grounded, anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same
points as the anti-static mat. During configuration and installation touch a grounded surface frequently to discharge any
static electrical charge that may have built up in your body. Avoid touching the components when handling the
motherboard or a peripheral card. Handle the motherboard and peripheral cards either by the edges or by the peripheral
card case-mounting bracket.
