What are the registers?

The chipset registers are pretty simple, they are memory locations in the northbridge that control the way it behaves. They control every aspect of the northbridge. Now as the northbridge is responsible for controlling the CPU, the memory bus, the AGP bus and the PCI bus, then its a pretty important part of your computer. The chipset registers are usually set by the BIOS at the time of boot-up, but by using some very useful pieces of software we can override these settings from Windows.
