CSME System Tools package for ME version 11, revision r46, compressed into a 12.6 MB RAR and newer than the r39 set. The v11 branch spans many Intel platforms, so these tools see frequent use for reading ME status, cleaning or rebuilding the ME region and preparing an image for an SPI programmer. Check which ME 11 sub-version the original dump contains, since some tools are version-sensitive, and always back up the BIOS chip before programming it.
