BCM MX945GSE User manual

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.
WARNING: Misplaced Jumper Damage
Incorrect jumpers and connectors settings may lead to damage to your motherboard and will void your motherboard
warranty. Please pay special attention to not connect these headers in the wrong direction. DO NOT change ANY jumpers
while the motherboard has power.

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.

your motherboard’s manufacturer warranty. Try Clear CMOS information when system does not boot after BIOS settings
change.
