Hi,

I'm trying to run SeaBIOS in an environment where I have difficulties with enabling a shadow RAM. Is there a chance to w/a requirement for writable 0xF000 seg in SeaBIOS? Could some of group members briefly estimate a scope of necessary changes?

SeaBIOS stores global variables in the f-segment, and so it requires that the f-segment be writable. Requiring that the f-segment be writable was a significant code simplification - I don't see a way to remove that requirement without re-introducing the associated complexity. -Kevin
