This is an Intel Management Engine a.k.a Intel ME firmware loader plugin for IDA.
To use it simply put the meloader.py file and _ meloader directory under the loaders directory of your IDA installation.
It was tested on Intel ME firmware versions 9.x and should work on all other versions prior to 10.x (but, of course, that is not guaranteed :).
