    But take a look at the posts made under this topic, [CentOS] Ethernet puzzle. Quite a bit is discussed in helping the OP there.
    Interestingly, it works with CentOS but the current version (6.5) is not working well with Haswell integrated video. Fedora works differently. It uses the MAC Address to bind interfaces to connection information. Found an entry on Fedora's forum, but no answer: Accidentally MAC address duplicated, "eth0-eth1" interface problem? - FedoraForum.org

    The only answer that I get from the Fedora's forum entry is that I have a messed up BIOS/EPROM. I wonder if someone knows some utility or some Asrock contact to flash a different mac address on bios. I've spent hours trying to make Fedora work. Even if I can make it work, I'm not sure that I woundn't have the same problem with a new OS that relies on mac address to assing ip/network policies.

    Well, no luck with Fedora: Features/NetworkManagerNameBasedConfiguration - FedoraProject

    It uses only the mac address to bind policies to nics. No options available at this time

    Use one of the below contacts and inquire of a MAC address utility for this MB. The MAC addresses should be noted on a sticker(s) on the MB with which to use with the utility.

    The local dealer found this tool on Asrock site: ASRock > Support > K7VT4A+ & K7VM3 Mac Tool Download

    Into the archive I saw that it have folder for distinct nics, including Intel. But this morning something bad happened: when I turn on my computer, it froze when loading linux. I then tried with the Live CD, also froze. Tried to load default configuration in bios, then the motherboard would not boot anymore. It kept showning error 62 (Chipset Error). Clearing CMOS with the back button did not work. Changing to BiOS B did not work either. I was only able to make it work clearing the CMOS with the jumper and removing the Radeon 4870 (it was the only thing besides HD pliugged on the system). After some tests I found out that my 4870 is dead. Don't know if the mobo did it or it was just a coincidence since it was already old, but I will try to request the RMA of the mobo.

    Bummer.

    Then again, hopefully you won't have this headache with the new one. Still, that sux.

    After that sad moment of loosing my 4870, I realized that sometimes it was giving me some unexpected behaviour, so I think it was a death by natural causes. I think that the other time I had to clear cmos was because of the video card too.

    Emily sent to me the tool to change the mac address and it worked like a charm! To avoid sending back the mobo to only loose time and money, I will continue to give it a try.

    I'd like to thank Wardog, Parsec and Emily for all your help!
