I noticed on 4.16 release notes Intel Alderlake-N RVP was added as a new supported board. I don’t know if that means Intel Alderlake N100 and other “N*” like N200 intel processors are also supported or only a particular one. If N100 would be included into the processors supported, is ME disabling supported, or at least mitigating its privacy risks supported?

On the same release notes, as part of the significant changes, it’s mentioned ME is now disabled from skylake to alderlake. So I’m hoping disabling ME on alderlake n100 is actually possible.

I don’t know if more boards besides the RVP one (which I don’t know which one it is) can be supported.

I acquired a Trycoo WI-6 Mini PC [2] with tho hope I could use coreboot on it and more importantly, disable ME on its intel processor.

Information of the device, in case useful:

Some information, as you can see, is not provided by the OEM. But as Intel Alderlake-N RVP was added as a new supported board some releases back, I’m hoping that means this board can be flashed with coreboot and more importantly ME can be somehow disabled for it.

Does anybody know, and if so what does it need to be done? Are there some instructions?

Thanks !
