I whole-heartedly disagree. With no cards in the box, the on-board port is port 0. With a card in, it changes, which makes it wrong. Adding a device should not change the port designation of the first device. The folks at 'BSD and windoze disagree with you also. its pretty difficult to label an enclosure when the port changes depending on what cards you have in the box.

With this approach the interface could be name "eth0" or >"fizbot23", it just didn't matter. The downside is that doing this makes >configuration *much* more obscure for the common single-interface >configuration. Try to sell a modular product with that philosophy..... With an SBC system, Linux detects the on-board controller first, and then the card. However with this MB, it detects the card first. Inconsitency is worse than doing it wrong all the time...... is this a driver or OS issue? Dennis - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.rutgers.edu
