1.13 Jumper Settings

There are three jumper blocks on the AP440FX motherboard. The jumper block at J1J1 defines the
number of PCI slots (two or three slots) available on the riser board used with the motherboard.
The jumper block at J4L2 defines a range of microprocessor and motherboard configuration
parameters. The jumper block at J8A2 is used to provide 3.5 V for processors that require that
voltage. Figure 8 shows the jumper block locations on the motherboard, and indicates how jumper
placement corresponds to the value defined by the motherboard silk-screening.
