Hello,
thanks for the feedback. What version of Coreboot did you use? Is the
stable 4.7 enough or should I use a snapshot from the git-repository?
Also the question how to include the VGA-bios for the NVidia-card. I
did
a compilation with the VGA-bios for Intel and included the rom
afterwards with cbfstool. Is this the correct way to do as "optional
rom"?
Thanks!
Regards,
Tobias.
Hello,
I'm currently using the latest Git snapshot on my machine. I also
compiled with the Intel option rom and added the nvidia option rom
using cbfstool after, like you did. I haven't tried 4.7, so I couldn't
tell you how it works there.
Regards,
Michał Kopeć
