[Lilux-help] strange network interface names

Hi, I have a strange problem... I have a box running ubuntu dapper, and all is fine. Now I cloned the disk, and put it into another box which is 100& the same hardware, and it still works fine, apart of one thing... What was eth0 and eth1 before is now eth2 and eth3 :-/ root@box:~# ifconfig -s -a Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg eth2 1500 0 1071 0 0 0 638 0 0 0 BMRU eth3 1500 0 0 0 0 0 0 0 0 0 BMU lo 16436 0 66 0 0 0 66 0 0 0 LRU sit0 1480 0 0 0 0 0 0 0 0 0 O root@box:~# How can I go back to eth1/2 ? Best regards, Yves p.s. The NICs are an e1000 and a via_rhine, and unfortunately I found no way of forcing the interface name on module load, that would be my preferred solution...
