raid5 plus vista

This is a new installation. I have the raid driver set but vista
seems to have no way to install them. XP does it ok.
One suggestion was to copy the vista dvd to the harddrive and then
copy the raid drivers somewhere in vista, make a new dvd then install
as per usual and the raid drivers would load in with the rest of the
drivers during install. This sounds like a good idea. Does anyone
know where to put the drivers inside vista?
