CPU Voltage Settings
J30 has been added to the CPV5000 with the introduction of the AMD
processor, because Intel and AMD processors run on different core voltages. If
you are using an Intel processor, then you should jumper J30. If you are using
an AMD processor, then leave the jumper off.
If your board does not have a J30 jumper, then it is not equipped to use the
AMD processors.

Ethernet configuration
The Ethernet configuration jumper is a three by four jumper block. A four
position shorting block is installed to select the Ethernet routing. To maintain
signal integrity, the Ethernet signals can be routed to the front connector or the
rear connector, but not both. Table 3-3 indicates which side the shorting block
should be installed to select the front or rear connector.
