Well, the chipset is like the heart. The chipset controls the system and its capabilities. It is the hub of all data transfer. Chip sets are integrated, meaning they are soldered onto the board and are not upgradable without buying a whole new motherboard. All data must go through the chipset.
All components talk to the CPU through the chipset.
To make order out of all this data, the chipset makes use of the DMA controller and the bus controller. The chipset maker needs to keep up with BIOS and memory makers, since all of these parts work together and the chipset is the hub of it all. Inc. All Rights Reserved.
