Updating an mb chipset driver
The most important of these chips are called the motherboard chipset.
When they give you a list of names it means that they're all variants on the same design and will use the same chipset driver.
The southbridge is a support chip which provides things like USB ports, network connections, and disk drive controllers.
Sometimes the northbridge and southbridge are built into one chip in which case it's still called a chipset even though there's only one chip.
To install your chipset drivers, the first thing you have to do is figure out which chipset is used by your motherboard.
CPU-Z is a free program which can identify the chipset on almost all PC motherboards.The southbridge for this computer is an Intel 82801JR which is also known as the ICH10R. For example, a chipset which shows up as Intel i875P may also be referred to as an Intel 875 or Intel 875P.
