Static Electricity Precautions

Static electricity could damage components on this motherboard.
Take the following precautions while unpacking this motherboard
and installing it in a system.

1. Don’t take this motherboard and components out of their

original static-proof package until you are ready to install
them.

2. While installing, please wear a grounded wrist strap if possible.

If you don’t have a wrist strap, discharge static electricity by
touching the bare metal of the system chassis.

3. Carefully hold this motherboard by its edges. Do not touch

those components unless it is absolutely necessary. Put this
motherboard on the top of static-protection package with
component side facing up while installing.

Pre-Installation Inspection

1. Inspect this motherboard whether there are any damages to

components and connectors on the board.

2. If you suspect this motherboard has been damaged, do not

connect power to the system. Contact your motherboard
vendor about those damages.

a dialogue box (shown as below) pop out warning you this

software has not passed Windows Logo testing to verify its
compatibility with Windows XP. Please rest assured that our
RD department has already tested and verified these drivers.
Just click the “Continue Anyway” button and go ahead the
installation.

2. USB 2.0 Driver Limitations:
2-1.The USB 2.0 driver only supports Windows XP and

Windows 2000.
2-2.If you connect a USB 2.0 hub to the root hub, plugging
USB devices into this hub, the system might not successfully
execute certain USB devices’ connection because it could not
recognize these devices.
