I'm at 3.4 and upgrading to 4.0, and while reading the Waninkoko instructions it said I needed to have the Cios_Fix installed first. I can't remember ever doing Cios_Fix. I have no memory of doing it, but my memory is horrible so maybe I did. How can I tell if it's been done? Would I even be at the point I'm at without it? If I can't tell, is it ok to just install it, possibly again, while already on Rev. 12?
