Flexible I/O Lane Selection

HSIO lane configuration and type is statically selected by soft straps, which are managed through the Platform Flash Image Tool, available as part of Intel® CSME releases.

Note:It is the responsibility of the platform designers to configure the lane muxing and soft straps correctly without any conflict. The hardware behavior is undefined if this scenario ever happens.

PCIe*/SATA Lane Selection

In addition to static configuration via soft straps, Flexible I/O Lanes that have PCIe*/SATA multiplexing can be configured via SATAXPCIE signaling to support implementation like SATA Express or mSATA, where the port configuration is selected by the type of the add-in card that is used.
