The second one is detected that way (which led to some fun with its MAC address not matching the HWADDR that kudzu had previously put in ifcfg-eth0) but that doesn't help once the first one is enable again. > Check to see if drivers are loaded. They are. I also downloaded and built the nvnet driver from nvidia.com, and turned off the forcedeth driver, but that doesn't change anything. I'm going to transcribe a little section from the motherboard manual here and then tell you what I see in /etc/sysconfig/hwconf. The manual: Dual Gigabit LAN AI NET2 Marvell(R) 88E8053 Gigabit LAN controller Marvell(R) 88E1115 Gigabit LAN PHY NVIDIA nForce(TM) 4 SLI built-in Gibabit MAC with external Marvell(R) PHY supports: - NV ActiveArmor - NV Firewall My first thought is "what the heck is an SLI MAC?" SLI is supposed to be video display technology. Now here's hwconf: class: NETWORK bus: PCI detached: 0 device: eth1 driver: unknown desc: "Marvell Technology Group Ltd. 88E8053 Gigabit Ethernet Controller" vendorId: 11ab deviceId: 4362 subVendorId: 11ab subDeviceId: 5321 pciType: 1 pcidom: 0 pcibus: 5 pcidev: 0 pcifn: 0 - class: NETWORK bus: PCI detached: 0 device: eth0 driver: nvnet desc: "nVidia Corporation CK804 Ethernet Controller" network.hwaddr: 00:15:F2:66:49:A7 vendorId: 10de deviceId: 0057 subVendorId: 1043 subDeviceId: 81d3 pciType: 1 pcidom: 0 pcibus: 0 pcidev: 13 pcifn: 0 I've tried manually creating an ifcfg-eth1 and pointing the sk98lin driver at eth1, but all that accomplishes is generating a message about "device appears not to be present". Incidentally the sk98lin driver works fine on eth0, too -- as do both forcedeth and nvnet. None make any difference to eth1. What I suspect is happening is that a single (?) nVidia SLI controller is somehow intended to operate both Marvell NICs, and Linux is not able to distinguish them as separate devices. But I'm not enough of a hardware geek to know for sure.
