cnr slot and acr slot

[hlin]

Hello:
finally got a chance to do some hardware reading. Ran into CNR slot and ACR slot. I not too sure what the two slot are for. Can anyone inform the uninform? Thanks

Special connectors that rise up from the motherboard and allow original equipment manufacturers to put there own board on the mobo, say a combo modem, sound, vid card.

you can't get anything for them in my experience unless you work for HP, Packard Bell, compaq etc and can nick one the customised thingies. My understanding.

The CNR Riser and the ACR Riser specifications were another battle being waged by AMD and Intel before Broadband started expanding into what its become today. These 'specifications' were made to provide integrated networking solutions for hardware manufacturers without sacrificing too much in the way of space, and making it an easy communication option for mainboards that previously had no support for them

AMR Riser - Intel - Audio and Modem Riser (AMR)
Software Based.

CNR Riser - AIntel - Communication and Networking Riser
Hardware Based / Chipset Dependent

ACR Riser - SIG/AMD/etc - Advanced Communication Riser
hardware Based / Chipset Dependent

Nice info Dracas, and another thing, most HP Compaq OEM systems are almost impossible to upgrade, better chucking the mobo that comes with them in the bin and getting new.

I think I'd have to agree Ammok, as I've found it more cost effective and reasonable to manufacture my own systems rather than turning to the proprietary options provided by Compaq, Hewlett Packard, or worse: eMachines.

As for the info, thank the internet, sometimes I just go read up on things. I've had that link bookmarked since my CompTIA exams back in 2001 :)
