which support
bifurcation of the
PCIe x16 IPEX
interface to two x8
PCIe interfaces, this
pin is used for either
the motherboard or
the network adapter
silicon to signal
whether the IPEX
interface should or
should not be
bifurcated. This
signal has been
reserved and hasn’t
been used in the
past, and as a result
it’s direction has not
been fixed yet, to
provide for
additional options in
the future. (pin is
marked as Reserved
06 in the generic
White IPEX Cable
pinout)
