Igor Skochinsky has created JEFF-Tools, tools for use Intel Management Engine. JEFF-Tools currently contains 2 tools:
dump_jeff.py
This script allows you to dump the JEFF files used by Intel ME’s DAL (Dynamic Application Loader). It supports the following input formats:
raw JEFF file (‘JEFF signature’)
JEFF packaged as an ME applet with signed manifest header ($MN2 magic) (currently ME 8-9.5 only)
any binary containing an uncompressed JEFF file inside (e.g. JOM_mod.bin produced by unpacking an ME firmware)
unp_dalp.py
This script unpacks DAL applets from a .dalp file (such files are used by Intel to package several ME applets into one XML).
