Tech Support Forum - View Single Post - P4C800-E PCI-CSA bridge not recognized

(I first posted this in the MB, Bios, CPU forum, but since it is an Asus MB, I'm re-posting here.)

I have been trying to get the onboard LAN working on a P4C800-E MB (bought used - not sure if the onboard LAN ever worked). BIOS has been updated, all of the Intel chipset drivers installed, etc. Everything is actually working very nicely except for the onboard LAN (an installed NIC is working fine ... using it at this very moment). All of the usual suspects have been tried (LAN enabled in BIOS, etc).

From searching through various posts here (lots of useful info), one thing looks suspicious - from Clintfan's Chipset Software Installation Utility post, I expected to see "Intel(R) 82875P Processor to PCI to CSA bridge", but I'm not (I'm seeing every one of the other "Intel(R) 82875P" and "82801" devices as expected). I do see a "Intel(R) 82801EB PCI Bridge" but don't see "CSA" anywhere in the Device Manager list. Obviously since Device Manager does not show anything appropriate, trying to update to the drivers from the Asus site download (and even the Intel site downloads) don't do anything.

Any ideas? Is there some kind of hardware jumper I missed reading about in the manual? Is this symptomatic of bad hardware? Or is there something else obvious I have not tried?

I have 160 GB SATA and a 160 GB ATA HD's installed, with the primary boot drive being the SATA drive (where Windows is installed). No RAID configured ...

Thanks!

Cliff
