If the 3c59x driver is built in, and the other drivers are loaded as modules, the 3c59x interfaces will always have the "lowest" names. It's possible to rename network interfaces, but that is a Very Bad Idea. > Just for testing I tried to reverse their order by a lilo parameter: > linux ether=0,0x2080,eth0 ether=0,0x2000,eth1 That won't work -- PCI drivers cannot override the I/O address.
