JP4 - LCD Panel Voltage Selection
JP4 selects voltage level to the LCD panel.
When the jumper is in position 1-2, the voltage level is set to 3.3V.
When the jumper is in position 2-3, the voltage level is set to 5.0V.

JP5 - PCI Bridge FPGA
JP5 is used to enable or disable the PCI bridge FPGA.
When the jumper is in position 1-2, the PCI bridge FPGA is disabled. This position must
be used for non-PCI host.
When the jumper is off, the PCI bridge FPGA is enabled. The jumper must not be present
for PCI host.
