One way that should work in 2.6 would be to build the driver in (not a module) and pass the addresses on the boot param line. netdev=3,0x300,eth0 netdev=5,0x200,eth1 or insert module manually modprobe ne io=0x300,0x200 irq=3,5 Not sure how to get same effect with modprobe.conf - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
