Recently my project just update Intel ME 220.127.116.117 (8M SPI)
And it seems will let my system fail to recognize PCI-E device. (Ex CF cardreader controller. (through PCI-E I/F) and WiMax wifi device.
I had checked descripor but no any clue. (maybe I lost something but don't know)
And if I clear ME region by dummy binary but keep the same BIOS region, it could recognize these two devices.
May I know is there anyone had experienced this kind of issue?
If someone coud provide some hint will be very appreciated.
