I've installed FC4 on an older machine but I can't seem to get ethernet card to work. It's a 3Com Etherlink III 3c509B. I've seen several sites that say it works... http://www.linuxcompatible.org/3Com_3c509B_c9932.html but none that really explain how to do it. A couple have mentioned some LILO parameters... but I'm using GRUB. One had the source code for a supposed driver, but it wouldn't compile. At this point I'm stumped. Anyone have any ideas? THanks
