Configuration of the PCI bus power supply (not for SX2-express QuadBRI)
On the right side of the SX2 QuadBRI is a three-pole jumper field for setting the PCI bus power supply.
 
Make sure that the jumper is at the correct setting for the computer's main board.
Left ("3V3 reg") for an environment with 5V, right for an environment with 3.3V, which will be found on older main boards.
