function Mini PCIe/mSATA socket.
The dual purpose functional Mini-PCIe/mSATA socket located at P8 can accept either a Mini PCIe
module or an mSATA module. The slot has circuitry that allows for the selection between connecting
PCIe lanes or SATA lanes to the connector. This slot also contains a USB 2.0 link as per the Mini PCIe
specification.
