Thanks Peter. I appreciate your work on Coreboot, and your insight above.
I would still be interested in working .config files for the X201,
though ;) Why? Not only to see if your (or someone else's) .config
would succeed in building Coreboot for my X201 with native graphics
init, but also because more generally, from the perspective of
reproducible builds and reproducible research, it would be great to
see Coreboot users and developers publishing, for builds that they
- the .config ,
- the Git revision,
- whether me_cleaner was used,
- a hash (e.g. SHA512) of the resulting coreboot.rom , if the build succeeded,
- the success or otherwise of booting the build, and
- maybe the coreboot.rom file itself.
But perhaps I should air that general wish in another thread some
time, instead of hijacking this one! I should also research whether
anyone has aired similar wishes already :)
