Bad news, you have a `QM67 Express Chipset Family LPC Controller` so you have ME hardware on board and you can't control or disable it, continuing...

To mod Aptio bios, you first have to remove it from the Aptio encapsulation using UEFItool to extract it (http://www.win-raid.com/t455f16-Guide-How-to-flash-a-modded-ASUS-ASRock-Gigabyte-AMI-UEFI-BIOS.html)

Otherwise, in regard to the ME, the trick is to use AMIBCP (4 for Aptio IV 5 for aptio V)to toggle an option to on under the flash options for these ASRock boards that forces an ME update on flashing. I also put a slightly newer ME version image in the bios using the intel tools (http://www.win-raid.com/t596f39-Intel-Management-Engine-Drivers-Firmware-amp-System-Tools.html) and toggled some other options to allow flashrom to work later too, all before stripping.

I also used UBU to update the microcode.

Once done modding the image, you need to flash an old version of the bios first, prior to the modded image's version. Then flash your modded version twice. The first time will get it installed, the second will trigger the ME image re-flash.
