875P Chipset
The Intel 875P chipset consists of the following devices:
• Intel 82875P Memory Controller Hub (MCH) with Accelerated Hub Architecture (AHA) bus
• Intel 82801ER I/O Controller Hub (ICH5-R) with AHA bus
• Intel 82802AC (8 Mbit) 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-R is a centralized controller for the Desktop
Board D875PBZ’s I/O paths. The FWH provides the nonvolatile storage of the BIOS. The
component combination provides the chipset interfaces as shown in Figure 8.
