1.6 Intel ® 810E2 Chipset
The Intel 810E2 chipset consists of the following devices:
82810E DC-133 Graphics Memory Controller Hub (GMCH) with accelerated hub architecture
(AHA) bus
82801BA I/O Controller Hub (ICH2) with AHA bus
SST 49LF004A 4 Mbit firmware hub (FWH)
The GMCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the
Accelerated Hub Architecture bus. 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
interfaces as shown in Figure 3.
