# obtained from the PCI Express interface if possible.  For
# slot based form factors, a system reset signal is usually
# present on the connector.  For cable based form factors, a
# system reset signal may not be available.  In this case, the
# system reset signal must be generated locally by some form of
# supervisory circuit.  You may change the IOSTANDARD and LOC
