NVIDIA System Tools is also a
front end for the BIOS. Most settings that can be changed in the BIOS are available in the utilities included. BIOS and driver updates to both nForce and GeForce hardware can also be done through System Tools. It additionally supports hardware which is certified under the
Enthusiast System Architecture and connects to the motherboard via USB.
