1.8 Chipsets
This section describes the chipsets used by the D815EEA2 and D815EPEA2 boards:
• The D815EEA2 board uses the Intel 815E Chipset, described below.
• The D815EPEA2 board uses the Intel 815EP Chipset, described in Section 1.8.2, beginning on
page 31.
1.8.1 Intel
®
815E Chipset
The Intel 815E chipset consists of the following devices:
• 82815 Graphics and Memory Controller Hub (GMCH) with Accelerated Hub Architecture
(AHA) bus
• 82801BA I/O Controller Hub (ICH2) with AHA bus
• SST 49LF004A Firmware Hub (FWH)
The GMCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the
AHA bus. The ICH2 is a centralized controller for the board’s I/O paths. The FWH provides the
nonvolatile storage of the BIOS.
The Intel 815E chipset provides the interfaces shown in Figure 5.
