Then use the slot attribute, if your BIOS supports that. If it doesn't, then there's nothing you can do, pci ids can be randomly assigned, and you should never make any assumptions based on them. I had a bios that would change the order every other boot, was great for testing things like this out. sorry, greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
