I just installed FreeBSD 5.4 on my Abit AA8-DuraMax, but I’ve run into some troubles with my networking. It seems that the on-board NIC doesn’t properly detect when a cable is plugged in. ifconfig shows it as “status: no carrier”

I know it’s not the router or the cable, because they both work fine on other machines. The 8100S chipset is listed as supported on the FreeBSD 5.4 Hardware compatibility list, as well as the man pages for the re driver.

Some other weirdness: If I plug the ethernet cable from the BSD machine to another machine’s NIC, it is properly detected. It only doesn’t detect when connected to my router. Also, if I manually set the card to 10baseT/UTP using ifconfig’s media parameter, it also works. It doesn’t work on autoselect, or any other media setting besides 10baseT/UTP.

Anyone have any ideas? Some info:
