wow dude, there's a full party into I-ME :S
i send this to the list, maybe other's interested too :)
The PDF from Igor Skochinsky that i found in the link you send me is
full of great resources! recommended (foot notes) <<<<<<<< ++ !!!!
if i've understand you right, we want to break intel's ME. We can call
that "write protection" firmware, but maybe i will call it "faulty
firmware to break intel's ME and avoid future changes vía software".
Now is time to check the resoults :)
i have this for windows, maybe can help you (could this be launched from
hiren's cd boot live windows XP? u will tell ;):
https://downloadcenter.intel.com/download/19009/Intel-Management-Engine-Verification-Utility
i also see in the kernel documentation that there is a module able to
talk to intel's ME (probably not fully tested, not fully featured, but
can give you some "working-notworking" scenarios.
