I’m pretty sure coreboot was only available on the Chromebook fw which is no longer available

I dont see it as an option when configuring the 16 for purchase, but if it’s available somewhere I’d be interested as I already have one.

I believe they only have their custom bios and no word on coreboot support. Rumors are that they recently hired someone to work on getting coreboot working, but until framework themselves say something we wont know.
