17 No, neither of them replaces the BIOS in their machines with an
18 opensource version. There is no BIOS in those platforms, it's just
19 uboot or fastboot, the PC-like ecosystem is so vastly different it's
20 laughable.

27 And I agree with that developer.

29 Don't get "replace all of userspace and the kernel" confused with
30 "replace the UEFI bios". You do realize that the UEFI bios is at least
31 double the size of the Linux kernel, with custom device drivers and tons
32 of other stuff in there? Good luck replacing that...

41 You are taking secure boot out of their systems, that sounds like taking
42 away an option to me :)

44 Anyway, it's all a moot point, as has been explained already, sorry.
