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 interference.
•
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 one serial port, one parallel port, four USB ports, one LAN Port and the audio
connectors.
