I cannot really follow that guide as IORegistryEntry shows no entries for a LAN card...

In fact, I reinstalled fresh from kalyway then to 10.6 and throughout the whole process OS X did not detect a ethernet card, at any point.

Could someone be kind enough to go into IORegistryEntry and look for their lan card as described in the guide airwalk posted? I don't think i'm crazy...

Before I fresh-installed, it would tell me "Not Connected" for both ethernet ports, and now they just don't show up at all.

I am using a 758-A1 board.
