Just wanted the clarify. Acquiring the drives is going to be difficult unless you know others whom have these same drivers. However there are sites which you may or may not be aware of that has his driver for download. Downloading anything can be risky. So think how important it is to acquire this driver as completed to getting a virus or spyware on your system from an unknown site.
Just wanted to say that sites like Dell offer this driver also, but it is the right one for you. Good Luck with your search.
