I did this for fun:

And now I'll actually get back to working on Libreboot. GNU Boot is inferior, for reasons explained here: https://libreboot.org/news/policy.html - but they wanted to fork Libreboot. Here is GNU Boot:
https://savannah.gnu.org/projects/gnuboot/
They struggled for months to get devs. They use super old revisions of Libreboot. I decided to help them, for fun :)
This version that I made is based on Libreboot from *today*, intended for re-use by the GNU project.
