BIOS was always heavily tied to x86 PCs, as it was a de facto standard in the first place by the fact that it was reverse engineered from the IBM PC. Of course, PC-compatible firmwares were never required for x86 PCs, but it made it convenient in the era when people would bring their own OS. When ARM started becoming popular, it was generally in embedded applications where the manufacturer was going to produce a single firmware to do a single task. It's only lately, since UEFI became the standard on x86-type computers, that anyone's bothered making a general-purpose enough ARM device where you might want to bring your own OS and that UEFI has been something that would be useful there

Yes. It's extremely common.

Yes, those use UEFI.

Almost nothing widely produced today uses old "regular BIOS". Even those which seem to use "regular BIOS" are largely UEFI systems acting like a legacy BIOS. Even things like Apple MacBooks which don't use EFI use an Apple custom similar firmware concept far removed from legacy BIOS.

What do you think will succeed UEFI ?

I dunno. Probably some kind of firmware interface standard. Hopefully it'll be extensible so the same base design can adapt to a large range of hardware profiles and features. It sure would be nice if it was a unified concept as well so there could be wide ranges of compatibility.

Only kind of kidding. I imagine the future for a while will either be continued growth into proprietary firmware platforms (like Apple and how tons of other phones/tablets have done) or a reworking/adapting of the main concepts behind UEFI but maybe making it less like ancient Microsoft-like patterns. Potentially something like u-boot becoming more common, or things like LK (Little Kernel). I think we'll see more evolution instead of hard replacement of concepts.

Only 99% of all non-embedded computing products that are faster than a few hundred MHz.
