The Intel 850 chipset consists of the following devices:
Intel 82850 MCH with Accelerated Hub Architecture (AHA) bus
Intel 82801BA ICH2 with AHA bus
Intel 82802AB FWH
The MCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the
AHA interface. The ICH2 is a centralized controller for the board's I/O paths. The FWH provides
the nonvolatile storage of the BIOS. The component combination provides the chipset interfaces
as shown in Figure 5.
