Intel Desktop Board D915GAV/D915GAG Technical Product Specification
1.7 Intel ® 915G Chipset
The Intel 915G chipset consists of the following devices:
•
Intel 82915G Graphics Memory Controller Hub (GMCH) with Direct Media Interface (DMI)
interconnect
•
Intel 82801FB I/O Controller Hub (ICH6) with DMI interconnect
•
Firmware Hub (FWH)
The GMCH is a centralized controller for the system bus, the memory bus, the PCI Express bus,
and the DMI interconnect. The ICH6 is a centralized controller for the board's I/O paths. The
FWH provides the nonvolatile storage of the BIOS.

1.7.1 Intel 915G Graphics Subsystem

The Intel 915G chipset contains two separate, mutually exclusive graphics options. Either the
GMA900 graphics controller (contained within the 82915G GMCH) is used, or a PCI Express x16
add-in card can be used. When a PCI Express x16 add-in card is installed, the GMA900 graphics
controller is disabled.
