I had a question about this passage: >"There's no reason not to make this improvement. Minnich noted, "There are probably 30 million-plus Chromebooks out there and when your Chromebook gets a new BIOS, a new Linux image is flashed to firmware and I haven't heard of any problems." Didn't or don't some generations of Chromebooks use Intel chips? Or is he not referring to the ring -2 and ring -3 Intel ME/UEFI stuff here?
