Most modern ones it’s just commands you have to run. You can usually find an easy walk-though on the MrChromebox website. I haven’t seen one that required a jumper or anything in a LONG time.

All of these machines make for decent Linux laptops. I picked up an EOL Chromebook for $35 last year and installed Debian on it. Decent little machine. Not terribly fast but very useable.

Literally zero down side and it’s safer.

Slower speeds are safer. There would be a lot less fatalities if everyone just went the speed limit.
