Nobody knows whether MS will pull a 180 and start supporting it in win8, though.
Microsoft supported EFI since Vista. Is uEFI something different?
So Q4 has almost ended yet there's been no news on the "OEM shipping coreboot on select motherboards" thing.
Pity, because I was looking forward to it...
I really hope it's still coming, my company is considering servers with coreboot support. And if someone supplies coreboot-boards with LGA2011 soon, then these would be considered for workstations as well.(but I believe Intel support is not great).
