This is very possible. I've seen problems of that sort with USB flash drives. (Very annoying!) > -- Hold the presses.

Possibly you would have to disable the MoBo device for the driver to properly talk with the PCI card. Of course since you are only really interested in having ethernet and would prefer to recover the PCI slot, this is unimportant. > But switching the cable back to the on-board controller I get a > message on the screen that the ethernet connection is restored and I > have internet access through th on-board controller. > > So please pardon my dumb-out.

But I still don't understand why the MoBo interface didn't show up under lspci.
