Eric may be too busy to explain freebios2 so I'll pitch in.
We are trying to freeze the current freebios code base (current goal is 5/15 since fixes keep rolling in) and give people something that works. First frozen version will be 1.0.1.
Then we want to move to a new 'cruft-free' code base. This seemed the right time to branch.
I would hope that folks who own mainboards, and who are committers, would start looking at the new code base and seeing what it takes to get moved to it. I will be personally starting work on an Arima K8 mainboard this week.
