Hi,I recently acquired an Asus Vivobook E406SA 1.0, which I have been investigating to see if there is a possibility to port to coreboot. While doing this, I seem to have found some weird information about Intel ME on this laptop. Although the CPU was produced in 2016 and it can be assumed that it includes Intel ME, all the tests I've done come up with the conclusion that it doesn't. I've included some detailed logs in an attachment 'me.txt'. Going forward, what can I do to verify if this laptop does have Intel ME or not? Flashrom doesn't support laptops well and I don't have the ability to risk bricking this laptop currently, is there another option to read the flash chip in this? - permanentjpeg
I forgot the attachment. Whoops.
