The issue you are experiencing seem to be related to your motherboard, I would like to know; have you contacted Asrock regarding this lock issue? How did you track down the issue to the Management Engine? Updating this driver may help.
year I contacted Asrock. But no response yet.
I have updated driver and flashed new ME Firmware. Not the software or version are the problem.
I searched for the that problem. ME device is an suspect device, which locks out your Bios and motherboard features.
Other people have the same isuses when ME is in secure mode.
So in ME info you can read:
Host Read Access to ME: Disabled
Host Write Access to ME: Disabled
