I dont mean to be me since I greatly appreciate what you do.. But everest only sees it as 2.0 also.. And password is alos reqiured.
Are you sure you have removed any software loaders for vista completely? Because if not, then RWeverything will be tricked into reading the fake bios (from the loader) in the same way windows are supposed to be tricked by the loader so if you got a Vista loader installed it will show Slic 2.0 info no matter what you have done to your bios...
It's just a thought.... VOATKtools 2.5 did the job for me on 2 machines that were previously soft-modded...
