@chilledHamza - cool you got it working now! 'MSR 0x2E aka CFG lock' is the standard mod everyone does to BIOS to allow MAC/OSX to run on mainstream desktop boards, it's the powermanagement mod.
You probably did this edit first, or some standard batch/process you followed covered this early on in the setup process.

Sorry, I can't really help on the EC FW Hopefully you can get it sorted out
