I've successfully installed Redhat 4.2 on my old 486. At the time it had no ethernet card. Now I want to add a 3com 3c509 ethernet card. I've found various drivers for this card, I've got a file called 3c509.c on my disk at the moment. Apparantly I have to re-compile the kernel (or something!) to get it to work. I couldn't get it to work. I am a total Unix / Linux idiot (I'm pretty good with MSDOS), so please someone give me some idiot instructions on how to do this. Some help on getting a TCP/IP stack working would be nice too.
