what is a CNR port?

[David Besack]

Was looking at a mobo with this spec listed:
Slots: 1x AGP 4X/8X, 3x PCI, 1x CNR

What is a CNR port? TIA

David,

It is an obsolete port that Intel was pushing. See this link:

Ah I see, for supporting something like another I/O panel. I can see
why it didn't take off.

It's a slot that was meant to house a hosted modem/lan card/broadband
modem. It never really caught on, so it's kind of useless, but you
still see them on new motherboards from time to time. In theory, it
was supposed to free up teh PCI bus, but in practice it made very
little difference. Anyways, the slot is practically useless, you can
safely pretend it doesn't exist.

The reason it's a 'special' slot is because it uses the onboard audio/DSP
and there's no access to those signals on the PCI bus.

It stands for "Communications Network Riser".

I have yet to find any card that will actually fit it. Seems like another
brilliant idea from the Wintel Monopoly Ivory Tower of Power telling us mere
mortals what we should have in our computers.
