I have a System76 Gazelle p8 that still serves me exceedingly well. Today I tried to use the new (?) system firmware updater but was not succesful:

clh@avignon:~/Dropbox/Timberline$ sudo /usr/bin/system76-firmware
2018-02-01 15:18:48,500 INFO gazp8 not known.
clh@avignon:~/Dropbox/Timberline$

I'm not completely surprised that this application only works for newer platforms, but I am wondering if there is some kind of reasonable alternative to achieve similar results (in today's case, disabling the Intel ME).

Anyone have any ideas? Thanks in advance!
