815E Chipset
The Intel 815E chipset consists of the following devices:
• 82815E Graphics and Memory Controller Hub (GMCH) with Accelerated Hub Architecture
(AHA) bus
• 82801BA I/O Controller Hub (ICH2) with AHA bus
• 82802AB Firmware Hub (FWH).
The GMCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the
Accelerated Hub Architecture interface. The ICH2 is a centralized controller for the board’s I/O
paths. The FWH provides the nonvolatile storage of the BIOS as well as hardware-dependent
security features. The chipset provides the interfaces shown in Figure 3.
