> Intel Boot Guard is an ME application introduced in  ... Intel Core i3/i5/i7 (Haswell) CPUs.  ... and prevent    the CPU from executing boot firmware that isn't signed with their private key.
> ME firmware versions 6.0 and later, which are found on all systems with an Intel Core    i3/i5/i7 CPU ... If the ME's boot ROM does not find in the SPI flash memory an ME firmware manifest with a valid Intel signature, the whole PC will shut down after 30 minutes ...
> Due to the signature verification, developing free replacement firmware for the    ME is basically impossible ...
> For years, coreboot has been struggling against Intel. Intel has been shown to be extremely uncooperative in general. Many coreboot developers, and companies, have tried to get Intel to cooperate; namely, releasing source code for the firmware components. Even Google, which sells millions of chromebooks (coreboot preinstalled) have been unable to persuade them.
