bonjour à tous et bonne année 
je viens d'installer une distribution gentoo sur une machine possèdant 2 cartes réseaux : une intégrée à la carte mère (msi 865pe neo2) qui est une Intel 82562ez, et une branchée sur le port pci qui est une 3Com 3C905C. voici le résultat de la commande lscpi :

Ma première question est :
Comment savoir à quelle carte réseau sera attribuée une interface ? (eth0 pour la carte interne, et eth1 pour celle branchée sur le pci) Et y a t'il un moyen de le changer ?
Le réseau ne fonctionne pas, du moins dans certains cas.
Voici ce qui se passe au boot :

Je pense qu'il doit y avoir une petite erreur mais je ne sais pas où alors si quelqu'un pouvait m'orienter, ce serait sympa car ça fait une dizaine d'heures que je cherche...
