I will be not able to comply to entire process, but here is a bit more... I guess, important below: (finding CPUID [CPUID 0x306A9 (SR0MM)] on the following www page): http://www.cpu-world.com/CPUs/Core_i7/Intel-Core%20i7-3720QM%20(BGA)%20Mobile%20processor.html Then, please, read this, in order to determine the latest MCU (seems microcode-m12306a9_00000019): https://www.coreboot.org/pipermail/coreboot/2014-January/077013.html Good Luck! :-) Zoran On Sat, Aug 27, 2016 at 8:55 AM, <[email protected]> wrote: > Awesome response to my question, thanks for breaking it all down.
