The interfaces supported by the CNR include the following:
• AC ’97 interface: supports audio and/or modem functions on the CNR card.
• LAN interfaces: an eight-pin interface for use with Platform LAN Connection (PLC) based
devices.
• SMBus interface: provides Plug-and-Play functionality for the CNR card.
The CNR connector includes power signals required for power management and for CNR card
operation. To learn more about the CNR, refer to the CNR specification.
The onboard two-channel audio subsystem can be upgraded to four- or six-channel audio using a
CNR audio upgrade card in a slave configuration. CNR audio upgrade cards are available in
multiple configurations from several vendors supporting analog or S/P-DIF digital connections.

INTEGRATOR’S NOTES
• If you install a CNR card that cannot support a multichannel audio upgrade, the Desktop
Boards’ integrated audio codec will be disabled. This only applies to D845GEBV2 and
D845GERG2 boards that have both the onboard audio subsystem and a CNR.
• The brand and type of audio codec used on the CNR card must match that of the Desktop
Boards’ codec (Analog Devices AD1981B).
• Check with your CNR vendor to ensure that the CNR card has been tested with
ICH4-based systems.
• There is no USB interface routed to the CNR connector.
