Back Panel Connectors
The motherboard external IO connectors are attached to a metallic I/O shield.
This shield serves several purposes:
•= It protects the sensitive motherboard from any external EMC problems.
•= It stops the computer from interfering with other electrical devices.
•= It allows the motherboard to be easily upgraded in the future without having to
resort to buying a whole new case. Simply change the I/O shield to match the
motherboard.
The I/O shield provides external access to PS/2 keyboard and mouse connectors as
well as two serial ports, one parallel port, the VGA port, RJ45 Local Area Network
(LAN) connection and two USB ports
