Well, this is a very old chipset. And, there is no "driver" per se. The chipset inf is just a definition, or names for devices you have.
So, why is this important? You are likely trying to get the latest graphics driver, for Windows 10. Correct me if I am wrong.
Now, the answer. If you are running Windows 10, there is no updated chipset inf, and the only driver you can get for your graphics is that which Microsoft provides.
So, if you are running Windows 10, there is nothing you can do because your chipset, and your processor, and your graphics are not supported.
If you are not running windows 10, then tell us what you are running,
