Under previous versions of Fedora, when I replace a motherboard, kudzu goes through a progress of asking me if I want to remove the old hardware one piece at a time and to install new hardware--for example VIA Rhine II network card. I am now running Fedora Core 4 and yesterday I installed a new motherboard. I installed a Gigabyte K8VM800M with a Sempron 64 2600+ socket 754 CPU. When I booted up, it does not ask me about removing or installing new hardware. Now when I shut down the machine, I get a message about the network card having a different mac address than expected . Is there some type of "Add new hardware wizard" or something that I need to run. ps The old motherboard was a Gigabyte 7VT600P-RZ socket A with an Athlon XP 2600+ cpu. The new setup is much faster as well as much quieter.
