don't break your device. The ME operating system resides in non-rewritable memory in u chipset or CPU. Editing the BIOS firmware does not affect the operation of the backdoor in any way.

if u want short answer what is doing me_cleaner with backdoor - this is it - nothing.
but u can try broke SPI firmware on old platform like 945gc - nouthbridge have'nt ME, but ich7 - is a ready AMT southbridge

and u all guys is doing nothing here many years.... how long will this continue?

If so why is there an ME partition in the BIOS firmware, and why do various vendors provide updates to the ME software via BIOS updates?

@kocoman1 If I understand correctly I think me_cleaner.py -S -r -t -d -O $OUTPUTFILE $INPUTFILE (the input file being a HP8300 BIOS image) is what you're looking for.

This is like operation system and installed some programs. ME Region contain programs and chipset or proseccor contain OS, like ThreadX or newest. But u need to understand that ME Region is not all repository and inbuild soprocessor memory contain hes one programs and can open some ethernet ports.

And real danger is in mind that ME and etc is only handy tool for guys from NSA and etc. So u need to read about ASF, DASH, SMM etc.

I think at this time most powerfull PC can build only on ga-945gcm-s2c and ga-945gcm-s2L with libreboot which can eliminate SMM and blob vulnerabilities. 945gc chipset not contained ARC soprocessor.
