Notes:
1.
This signal is not currently implemented in the FPGA to drive the blue LED activity indicator.
2.
Some PCIe modules use this signal as a second Mini Card wireless disable input. On the Viper,
this signal is available for use for mSATA versus PCIe Mini Card detection. There is an option in
BIOS setup for setting the mSATA detection method.
