Run this easy to use Intel® Driver Update Utility and it will "automatically" tell you if you need to update your chipset INF file, and if so, will prompt you to install and you are done. This will save you a lot of time not only on your chipset download but the most common files needed for your system.

Name changes:
Intel® Chipset Device Software is the new name for the Intel® Chipset Software Installation Utility; this name will be seen when running the installation package.
