2.7.3 PCIe x4 Interface Goldfinger
The PCIe x4 from the Intel® ICH9M consists of four lanes. The four lanes are connected
to a single golden finger as shown in
722H
Figure 2-13 .
Figure 2-13: PCIe x4 Golden Finger Connection
The PCIe x4 is interfaced to one PCIe x4 expansion card or four PCIe x1 expansion cards
on a compatible PICMG 1.3 backplane.
2.7.4 Intel® PC82574L PCIe Gigabit Ethernet (GbE) Controllers
There are two Intel® PC82574L PCIe GbE controllers installed on the PICOe-GM45A.
The Intel® PC82574L is interfaced through a PCIe x1 channel to the Intel® ICH9M. The
Intel® PC82574L controller is then connected to an RJ-45 Ethernet connector enabling
the PICOe-GM45A to be connected to an external network.
