    UEFI and BIOS are firmware interfaces. Coreboot is a firmware implementation. Coreboot has both BIOS and UEFI implementations.

      Well, BIOS did have some odd quirks and limitations. While it would be okay to remove these and add support for new tech stuff it is just ridiculous why that reference implementation had to be as large as the Linux kernel without drivers. I mean, what the heck. Things a little about 256 Kbyte size binary could do is now done in many megabytes?
      Of course mainboard vendors or the "bios" implementers make things normally even worse, that's true.

      The main job of this kind of software is just to wake up hardware (which can be complex enough already, just listen to some coreboot talks held on Linux cons), activate interfaces, maybe show the user a little screen with basic system info or an error message and finally give control to a kernel or a bootloader. I'm actually scared to know what else these huge UEFI blobs do.

        There was an article put out quite time ago which stated that Intel themselves made the claim that the initial batch of Bay Trail hardware will run 32-bit Windows 8.1 only, with 64-bit preloaded Windows 8.1 only being available some time next year.

        In hindsight, this may have been early warning about the 32bit UEFI firmware + 64-bit processr mismatch that we are experiencing with the T100 right now.

        By this logic, the time to get Bay Trail hardware for use with x64 Linux should be when such hardware loaded with x64 Windows start appearing in the market.

        (That said, Im curious; have anyone tried to slap on a 32bit Linux distribution to see if it boots on the T100?)

          michael, try to do this. Create a pendrive with gparted, formatting the partition table with gpt, and copy/past form the iso the files on a fat32 partition. it should work just like that.

            i actually realized that bay trail has no emt64 support on it, so this might actually be a total waste of time trying to boot anything 64bit on it. As the old atoms did, the actual circuitry is there but is disabled/burned.

            Edit: apparently according to intel's Ark, i'm wrong. They do have emt64;

              They do have emt64, but the question is, why did Intel announce that the initial batch of Bay Trail hardware will only boot 32bit operating systems.

              I doubt most people will even be able to install a fresh copy x64 Windows 8.1 into the T100 unless Microsoft bundles both 32bit and 64bit EFI images in their x64 install ISO.

                More of these systems from other OEMs are coming out, lets see if their UEFI implementations are any better...

                I'm really interested in one of those. Any luck on booting vanilla x86 distros?
