Hey dude,
From what I remember....first you need the "cnet.device" driver (aminet), install that, then you may also need "cardreset" and "cardpatch" also from aminet. Cardrest is pretty self-explanatory,, it fixes a hardware bug (IIRC), just keep in mind you may need to manually "adjust" the reset time with an argument if the default doesn't work (didn't for me). Cardpatch fixes 'slowdown' problems with PCMCIA usage and 040/060 processors among other things, again IIRC...check the docs to be sure. The latter are easy to install, just throw them in your c: drawer and run them from your user-startup or startup-sequence. After that you should be ready to setup your TCP/IP and off you go!!
