1. Does flashrom [1] support your board/system?
2. Do you have a backup plan? For example, can you take out your flash
chip? Do you have replacement chips to easily recover? There is some
information on this in the Wiki.
3. I do not know about it, but I think if 1. and 2. are resolved you
could just build an image and try to boot it and look how far you get.
You should have a serial cable to log the output.
4. If I remember correctly it is suggested to run coreboot v3 on Geode
systems until the features have been ported back to trunk.

Thanks and please correct me, if I wrote nonsense,

Paul
