No, the default config of a BIOS usually is to come up with EFI shell if
everything else fails.

Yes, that's the part that took me some time, too. ;)
However, the basic things are not that hard once you find out how it works.

Sorry, you lost me there.

I was talking about updating BIOS or firmware in your system here, not getting
a broken system online again. Updating usually involves some kind of Windows
software. As I don't use Windows, this doesn't help me. The fallback option
usually is something DOS-based (if it exists), but this requires some extra
steps. Having a EFI-based update tool is less of a hassle.

Which software are you looking for? Most things can be set up with efibootmgr
under Linux (or FreeBSD).
