Recently my project just update Intel ME 18.104.22.1687 (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.
Interesting - you might want to try to clear the CMOS. I'm assuming the system in question is a Notebook? Please provide more information, such as which system (OEM as well) you are having problems with. Also, did you install all the supporting driver upgrades when you upgraded your ME?
