PCI Express cable is 32-bit spec. We have not verified operation on boards for both 64bit and 32bit,
such as ADAPTEC's 39160SCSI board and Intel's Pro1000/MT network board.
PCI Express bus is x1 spec. Buses requiring baud rate more than x1 (x16, etc.) cannot be used.
Leave "Reserved" pins unconnected. Connecting these pins may cause a fault in this product.
