Something to do with free software everything, not features that Coreboot provides that a standard InsydeH2O UEFI BIOS doesn't have. I don't quite get it myself, and it is quite a niche, but some people care more about it more than others. A very small amount of people. There's great risk installing such a thing yourself, as you can end up bricking your laptop with very little recourse than to break out a soldering iron. Or if you don't do your homework carefully, end up with a half functioning PC because things like display brightness and audio apparently require driver binaries within UEFI that need to be there to work. That is a Clevo laptop, but many vendors do use their models and don't advertise as such. Gigabyte, for example, uses Clevo for their bottom tier models with no special marketing name. I don't doubt that their other models are Clevo, but I can tell that those ones are.
