Both results are attached. > Looks like the Management Engine region is totally locked (from both reads and writes), so it will fail whenever flashrom tries to read/write in that region; 0x5C: 0x05ff0001 (FREG2: Management Engine) 0x00001000-0x005fffff is locked We need to do some rather ugly stuff to hack around that. I have a very ugly hack that applies to the Chromium OS branch you can try: # clone chromium os branch of flashrom git clone http://git.chromium.org/chromiumos/third_party/flashrom.gitflashrom-cros && cd flashrom-cros # apply patch from https://gerrit.chromium.org/gerrit/#change,12117 git pull https://gerrit.chromium.org/gerrit/p/chromiumos/third_party/flashromrefs/changes/17/12117/1 With that patch, flashrom will fill in unreadable parts with 0xff bytes, and will not attempt to erase/write those parts. Verbose output will show "WD" (Write Denied) for regions that are unwriteable.
