btw: I have here some funny dialog from the ChromeOS forum where I asked
for some help, not about software but hardware of the C720; it seems
that they do not like that FreeBSD is installed on their beloved
funny to read:
The (high-resolution) picture of the mother board of the C720, which can
be found here
shows right of the screw 7 a black 2-wire cable, connected to the
motherboard and ending below in some black cylinder. Is this cylinder

your needs, rather than trying to force a Chromebook to be something it
Wrong conclusion of my post; the Acer C720 is one of the best netbooks
I ever purchased and it works fine with FreeBSD.
You are of course entitled to your opinion.
As this topic does not cover a supported use of the hardware, I am
going to lock it here.
