Run the Vista Upgrade Advisor for a definitive answer.
You got to be kidding... a "definitive" answer from the piece of junk
called the Vista Upgrade Advisor?
I used it, and it told me I would have NO PROBLEMS installing Vista,
proudly displaying a green check mark of approval yet noting it
couldn't find any information on some of my drivers. So I accepted
this "sage" wisdom since it came directly from a Microsoft tool and
attempted to install. At 21% in, it crashed with a 7B BSOD.
Only after I disabled the "questionable" drivers Vista advisor simply
claimed it didn't know about and further claiming they would NOT be a
problem, but may cause some "minor" issues, was I successful in
installed the business version of Vista.
My advise, for sure run the Vista Upgrade Advisor, but if it nags
about anything, even slightly or lists drivers of any kind or type it
can't find information on DO NOT attempt to install unless and until
your clear, disable or remove same devices from your system PRIOR to
attempting to install Vista or likely the install process with crash
before finishing generating a BSOD.
