You can do either.
Either copy the drivers directory into the 'Drivers' dir, or actually install them as part of the process with a silent option.
Putting them into the Drivers dir will be as if Windows had them there from the start. See a few posts previous for success.

Nvidia drivers (or any files ending with an underscore) are a bit of an exception as you need to expand them first: http://superuser.com/questions/63773...stallation-dvd
