Description
Advanced Digital Display Card – 2nd Generation. Provides digital display options for an
Intel graphics controller that supports ADD2 cards. This card plugs into a x16 PCI
Express connector but uses the multiplexed SDVO interface. Will not work with an Intel
graphics controller that supports DVO and ADD cards.
ADD2 Card
Core refers to the internal base logic in the (G)MCH.
Cathode Ray Tube.

CRT
DBI
Dynamic Bus Inversion.
Double Data Rate SDRAM memory technology.
A second generation Double Data Rate SDRAM memory technology.
The Direct Media Interface is the connection between the (G)MCH and the Intel® ICH6.
DDR
DDR2
DMI
Digital Video Interface. This is the specification that defines the connector and interface
for digital displays.
DVI
Front Side Bus. The FSB is synonymous with Host or processor bus

Full reset is when PWROK is de-asserted. Warm reset is when both RSTIN# and
PWROK are asserted.
Full Reset
Graphics Memory Controller Hub component that contains the processor interface,
DRAM controller, and integrated graphics device. It may also contain an x16 PCI
Express port (typically the external graphics interface). It communicates with the I/O
controller hub (ICH6*) over the DMI interconnect. Throughout this document GMCH
refers to the Intel® 82915G GMCH, 82915GV GMCH, 82915GL, and 82910GL, unless
otherwise specified. Note that term (G)MCH is used when referring to both GMCH and
MCH components.
GMCH
High Definition Multimedia Interface. HDMI supports standard, enhanced, or high-
definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC
HDTV standards and supports 8-channel digital audio, with bandwidth to spare for
future requirements and enhancements (additional details are available through
www.HDMI.org)
HDMI
This term is used synonymously with processor.
Host
An interrupt request signal where X stands for interrupts A,B,C, and D.
INTx
Intel® ICH6
Sixth generation I/O Controller Hub component that contains additional functionality
compared to previous ICH6s. The Intel® I/O Controller Hub component contains the
primary PCI interface, LPC interface, USB2, ATA-100, and other I/O functions. It
communicates with the GMCH over a proprietary interconnect called DMI.
Internal Graphics Device.
Liquid Crystal Display.
IGD
LCD
LVDS
Low Voltage Differential Signaling. A high speed, low power data transmission standard
used for display connections to LCD panels.
