Hello Rudolf,

I was able to get the mahogany coreboot to boot Win7 on an ECS A780GM-M3 board
with a family 0Fh processor installed. Here are the steps, starting with trunk:

1) Apply the revised RS780 patch (patch-rs780-2.txt).
2) Apply the Win7 changes (win7-wip-1.txt).
3) Apply the additional attached changes for family 0Fh (win7-mahogany.txt).
4) Revert file ht_wrapper.c. That quick and dirty HT3 change is not good for family 0Fh.


]I agree that this patch is big improvement. We can fix the MMCONF later.
