Just a quick thought. These days you can create a special partition in the first part of your drive and just boot from it. No grub, no config really. You might want to take a look at EFI and an EFI system partition perhaps?

Just in case - there are also good linux desktop applications - check out Authenticator on flathub for example.

In case you haven’t seen it already - 3mdeb shared some info on the state of things during last FOSDEM. If I’m not mistaken they also did an update the year before too.

I know of exactly 1 AMD corebooot laptop. Starlabs Starfighter.

For coreboot you’re basically on Intel. As others mentioned, look up dasharo. They have added support for two modern MSI motherboards and Intel cpu models.

From their readme:

For the project as a whole, it is not free. You are FORBIDDEN to distribute the apk compiled by you (including modified, e.g., rename app name “Shizuku” to something else) to any store (IBNLT Google Play Store, F-Droid, Amazon Appstore etc.).

I don’t get it?

Very well written article, very much worth a read.
