PCI Express Port 0 (ESI) Positive Phase Inbound: (Receive) Signals
PCI Express Port 0 (ESI) Negative Phase Inbound: (Receive) Signals
PCI Express Port 0 (ESI) Positive Phase Outbound: (Transmit) Signals
PCI Express Port 0 (ESI) Negative Phase Outbound: (Transmit) Signals
PCI Express Port 2
PCI Express port 2 is a x4 port. PCI Express port 2 is combinable with PCI Express port
3 to form a single PCI Express x8 port. Normally port 2 and port 3 are used to increase
the bandwidth between the Intel 5000X chipset MCH and the Intel 631xESB/632xESB
I/O Controller Hub.
