Re: [Libreboot] OpenBSD with libreboot on the X200

[Oriol Demaria]

Yes I have tried chainloading, but I can't chainload a BSD partition 
from libreboot Grub. What I do is chainload SeaBIOS and from there I 
have Grub in a partition, with that Grub I can indeed chainload the 
BSDs. But the problem lies in that BSD* (or Hurd I suspect) won't boot 
into framebuffer for now, while Linux does.

SeaBIOSVGA doesn't initialize properly the GM45 card of the X200. For 
that I need a BIOS backup of an X200 in order to extract this propietary 
blob, and include it as option rom. I have also downloaded BIOS updates, 
but I haven't been able to extract this blob. And I will be able to get 
rid of it when OpenBSD boots into framebuffer.
