Hi,
I have heard an unverified rumour that Atom substitutes the ME for an ARM
microcontroller running Trustzone.
If this is the case however, it's possible it's only for bringup, in which
case it's not too much different from the inaccessible micrcontrollers
already present in most x86 silicon.
(eg superio chips with their own baked-in firmware)
It's something worth looking into, but probably not even on the same scale
as the ME.
At the same time, a micro-itx board like this one would be FANTASTIC for a
NAS device, as many NAS-oriented cases with built-in bays are
micro-itx-only.
If such a board existed in coreboot with ECC support (not available in my
AM1I-A) a year ago, my own NAS build would have been quite a bit different.
Sincerely,
-Matt
