System Board
Your system is equipped with a Pentium II processor that
runs at 350 MHz, 400 MHz, 450 MHz, or 500 MHz (when
available), depending on the system you purchased. The
Pentium II processor has the MMX instruction set built in.
MMX-type components optimize a system’s ability to
process multimedia components.

WARNING
Should you have occasion to open your system,
before touching anything, be sure to ground
yourself. Electrostatic discharge poses a
considerable hazard to electronic components.
Service technicians ground themselves by
wearing a wrist strap that is attached to an
electrical ground, such as your system’s serial
port. A grounding strap is available at electronic
supply stores.
If you do not have a grounding strap, you can ground yourself
and dissipate any electrostatic buildup by doing the
following:
1.
Connect the computer’s power cord between the
computer and a three-pronged, grounded electrical outlet.
2.
Be sure power to the computer is turned off.
