Hey, I used the mini PCIe -> x1PCIe version with the same cable length from the same people to test the card in the WiFi slot successfully, so I doubt that it is a signal integrity problem.
I'll try to build against coreboot master on Monday and see what happens. How can I get the sort of logs that would help here out of coreboot? I'll be building with Tianocore.
