It boots, but still lacks many features. Graphics output is possible by integrating SeaBIOS as CSM, but various native components (such as a GOP driver that piggybacks on the coreboot framebuffer) are planned.

 '''[http://tianocore.org TianoCore]''' is an open source implementation of '''UEFI''', the '''Unified Extensible Firmware Interface'''. UEFI (formerly EFI) is intended to replace the traditional PC BIOS. TianoCore as in implementation cannot do that, as it lacks the code to do hardware initalization. Since hardware initialization is exactly what coreboot does, the combination of coreboot + TianoCore is the most straightforward option to provide a complete, opensource UEFI environment.
-There are various approaches for loading TianoCore, the easiest one seem to be to use SeaBIOS floppy mechanism and DuetPkg.
+There are various approaches for loading TianoCore. One is to use SeaBIOS' floppy mechanism to load DUET, a TianoCore-on-BIOS. The other is to make TianoCore a true coreboot payload.
