You can search for the keywords on PF5NU1G, BIOS, AMIBCP, EC and find plenty of discussions there (w/ info on making your own unlocked BIOS if you want), although the Tuxedo/Schenker people have also done a fair amount of work making sure the laptop works well with Linux. The point general of buying from a Linux computer mfgr is to get a supported machine, so if you don't trust Slimbook, you can order basically the same laptop (w/ a slightly better display) from Tuxedo or similar class Linux laptops from Star Labs, HP, System76, or Framework.
