1.8 Intel ® 865PE Chipset
The Intel 865PE chipset consists of the following devices:
•
Intel 82865PE Memory Controller Hub (MCH) with Accelerated Hub Architecture (AHA) bus
•
Intel 82801EB I/O Controller Hub (ICH5) with AHA bus
•
Firmware Hub (FWH)
The MCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the
Accelerated Hub Architecture interface. The ICH5 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 9.
