I agree, I normally would not do an upgrade install. But the hardware change is sort of unexpected, as I need to drop the hardware into another machine that died. And I expect there would be longer-term problems, but as this is a beta, I don't expect it to be too long-term anyhow, so I'd rather experiment with stuff like this at this point rather than in the future when I am actually expecting it to be a solid, final install.
So, I know that a clean install is best, and I may have to do it anyway, but I want to see what I can get away with first. I would think people have tried this already?
Oh, and I found the answer to one of my previous questions in the original post here: http://arstechnica.com/hardware/news...ng-windows.ars
That describes in more detail how to change the PCI IDE controller driver
to a standard driver, for anybody who is following the thread.
