A chipset driver is a type of driver that typically refers to what is needed for a computer operating system (OS) to properly work with and recognize the motherboard inside a computer. Basic chipset drivers are typically included as part of the install of an OS, though motherboard manufacturers also include specific drivers to allow the most effective functionality from the motherboard. The term may also sometimes be used to describe other types of drivers used for other internal components, such as audio and video cards, though this is often seen as an inaccurate usage of the phrase. A chipset driver can usually be found on a compact disc (CD) or other media that accompanies a motherboard, or it may be downloaded from the board's manufacturer.

Drivers are types of software specifically created to help an OS operate with a device or component that is a part of a computer or connected to the computer. A chipset driver refers to a type of driver that is created to help an OS better operate with the motherboard within a computer in particular. The motherboard inside a computer functions as the central hub, to which all other devices are connected in some way. These can be physically installed directly onto the motherboard, such as the processor, random access memory (RAM), and video card, or connected through a universal serial bus (USB) port or similar connector.

In order for the OS installed onto a computer’s hard drive to properly recognize and function with all of these installed devices, it typically must be able to first recognize and work with the motherboard. This is achieved through the installation of a chipset driver or drivers that indicate how the OS can identify and function with the motherboard. Most types of OS will have a basic chipset driver for just about any major motherboard on the market. This is done to ensure that a newly installed OS will work on a computer when it is first started up and has not been updated.

While an OS may have some chipset drivers, a CD or other form of media that comes with a motherboard will usually have a more specific chipset driver that can be installed. An updated chipset driver can also usually be downloaded from the manufacturer of a motherboard to more effectively take advantage of the motherboard installed. This can usually help solve hardware issues such as installed devices not always being recognized properly or RAM and video cards not functioning as they should.
