CNR
is the latest riser card specification to replace the AMR (Audio/Modem Riser) that supports V.90 analog modem,
multi-channel audio, and
a variety
of networking
with
Ethernet LAN, DSL, USB, wireless,
or phone-line based home
networking added. Owing to CPU computing power getting stronger, the digital processing job can be integrated into main chipset
and share CPU power. However, the analogy conversion
(CODEC)
circuit requires a different and separate circuit design, which is
put on the lower cost and flexible CNR card. Though this motherboard implements audio CODEC on board (can be disabled by
BIOS), it reserves CNR slot for the option of other functions, which means that you can still use your favourite PCI modem/LAN
card depends on your preferences.
