ME cleaner
A cleaner for Intel ME/TXE images.
This tools removes any unnecessary partition from an Intel ME/TXE firmware, reducing its size and its ability to interact with the system. It should work both with coreboot and with the factory firmware.
Currently this tool:
- Scans the FPT (partition table) and checks that everything is correct
- Removes any partition entry (except for FTPR) from FPT
- Removes any partition except for the fundamental one (FTPR)
- Removes the EFFS presence flag
- Corrects the FPT checksum
- Removes any non-essential LZMA or Huffman compressed module from the FTPR partition (pre-Skylake only)
- Relocates the remaining parts of the FTPR partition to the top of the ME region (pre-Skylake only)
- Checks the validity of the RSA signature of the FTPR partition
Don't forget to power cycle your PC after flashing the modified ME/TXE image (power off and power on, not just reboot).
See the current status or a more detailed description of me_cleaner.
