the motherboard from damage, use the
following precautions:
* Ground yourself to remove any
static charge before touching the
motherboard. You can do so by
using a grounded wrist strap or
by frequently touching any
conductive material that is
connected to ground.
* Handle the motherboard by its edges.
Do not touch the IC chips, leads, or
circuitry unless it is necessary.
* Do not plug any connector or jumper while the
unit is powered on.
