ESD Precautions
Computer boards have integrated circuits sensitive to static electricity.
To prevent chipsets from electrostatic discharge damage, please ta ke
care of the following jobs with precautions:
Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
Before holding the board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. It
discharges static electricity from your body.
Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

applied to either PCI Express or USB 2.0. The USB 2.0 support will be
helpful during the transition to PCI Express, because peripheral
vendors will need time to design their chipsets to have the PCI Express
function. During the transition, PCI Express Mini Cards can be quickly
implemented by using USB 2.0.

zSample of Watchdog application
Assume there is program A which needs to maintain runn ing in a

running time of program A. Then, after the running time of program A
is finished, either to disable or to reset watchdog timer.
