Not at FPF, so you can disable at ME FW if you want
For now, yes, it's enabled at ME FW, that will need disabled via FITc, then ME FW reflashed and state reset (-greset or power drain)
That does look strange! I've only seen enabled or disabled, never "Not Set"

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM

Zitat von Lost_N_BIOS im Beitrag #2

You mean the FPF? That's not strange. They have 3 states (Not set, Enabled, Disabled). "Not set" means that the PCH/SoC has not been committed yet with any value (Enabled, Disabled). The OEM is supposed to set one of the two policies via FIT(C), close manufacturing mode to commit to FPF (fpt -closemnf) and then ship the system. When it's left in an uncommitted state, you see "Not set". In this case, the OEM set the settings in (CS)ME but forgot to close manufacturing mode (closemnf). You can do whatever you want, BG wise.

@plutomaniac - Yes, I meant the FPF column, or just "Not set" in general, I've never noticed anyone's report say this, always either enabled/disabled usually.
Thanks for the info. I did wonder if something was not committed or closed when I seen this, so makes sense now

@plutomaniac @Lost_N_BIOS @DeathBringer
Thanks!I tried to add some module as with nvme.
After flashing,I tried to reboot the system and it's OK.And I found the module was added into it when I dumped the bios.
I unplugged the power cable,then plugged again the cable after a few minutes,the machine couldn't launch.I had tried to take away the battery on the mobo and put it back,but it still didn't work.
I had to tried to save it with SPI Programmer.

Should I do something with the ME region after modding the bios?(Disable ME should work?)
The bios below is the original bios dumped on the machine.

I had flashed the original bios by SPI programmer.I found once I changed the bios region(add microcode or nvme module),the machine bricked.
I tried to disable ME but nothing helped.

@gloobox - Sounds like random glitch brick or something, for your first post above. Since it was OK, and then not after you unplugged it.
ME Does not need disabled, or edited. Sounds like maybe back BIOS edit? How did you do NVME insert? Did you compare before/after BIOS side by side with UEFITool after ucode update?
Please give me original BIOS and I will do NVME mod and update microcodes, then you can test and see if same.
This is above BIOS at post #5, untouched, not modified? What is full model name so I can keep in proper folder

If edit I do is brick too, this not due to Boot Guard, but something else, some other check like RSA or other internal checksum or other issue.
