Intel AUGSBURG S775 I915G MATX 10PK KD915GAGLKPAK10 ユーザーズマニュアル

®

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.

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.
