"A number of integrated circuits designed to perform one or more related functions.

Newer chipsets generally include functions provided by two or more older chipsets. In some cases, older chipsets that required two or more physical chips can be replaced with a chipset on one chip.
The term is often used to refer to the core functionality of a motherboard."

Basically you need these drivers to correctly identify your motherboard chipset for Windows to make use of its functions like power related functions, going into standby, etc.
