1.11 Connectors
1.11.1 PCI Express Connector
The pinout of x16 PCI Express edge connector is as defined in the PCI Express Card
Electromechanical Specification Revision 3.0 with the exception that PCIe lanes [15:8] are defined
as a second PCIe link, lanes [7:0] respectively. On the base board, these are routed to CPU2 as
previously noted in this document.
