Hardware Management Subsystem - Intel D845PEBT2 Specification

The optional 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 different vendors supporting analog or S/PDIF digital
connections.
✏
NOTES
•
For an audio multi-channel upgrade, you must install an audio CNR card that is compatible
with the onboard codec.
•
If you install an audio CNR card that does not provide a multi-channel upgrade, the integrated
audio codec on the Desktop Board D845PEBT2 will be disabled.
•
Check with your CNR vendor to ensure that the CNR card has been tested with ICH4-based
systems.
