In summary, this is what I found: 1) As suggested, my cable was bad. I just could not bring myself to believe it. Somehow by adding the cable and the 2nd NIC, it was discovered that I added the bad cable and mixed it all up. But not before testing in multiboot why all of a sudden even XP/2K was not connecting to the switch. Also, there is one more monkey business to deal with: udev. 2) udev. Edited /etc/udev/rules.d/70-persistent-net.rules so that ethX assignments are in the correct order. Changing via system- config-network does not seem to change this and caused confusion on bootup and in the dmesg logs especially if the 2nd NIC was removed later and udev wanted to "swap" eth1 for eth0 when eth0 did not exist. It was definitately confusing. 3) The confusing auto-assignment of devices in system-config-network, that is, dev0-dev8 with weird extra numbers added such as network device: dev23546 threw me off. What I did was to force via two hardware places, one in 'Devices' tab, profile-card, and the 'Harware Devices' tab, and the other in 'Harware' tab, on the right of 'Devices' tab. It seems you have to select your NIC eth device selection via 'Hardware' tab, then go to the 'Devices' tab, select your NIC profile, click 'Hardware Devices' tab, and then click the dropdown list next to label: 'Harware' and select the new eth device assignment. Wierd. Well, for now I am happy as a clam and my primary Attansic L2 on chip NIC works and I still have my IntelPro NIC on standby in case I or 'acts of god' screws it all up again. Sigh.
