I had a hard time with this one originally, but fortunately Markus Schmidt helped me out with it. Well, I came across this problem yet again last month when installing OPENSTEP on a secondary drive for my ThinkPad. As it took me a long time to solve the problem and I know other people have had the same problem, I'll detail what I did to get it to work (in Rhapsody, but the same applies for OPENSTEP). Base drivers: 3Com EtherLink III PCMCIA Adapter (v5.01) ISA/EISA Bus Support (v5.01) PCMCIA Bus Support (v5.00) Intel 82365 PCMCIA Adapter (v5.00) What Card? As it turns out not all 3Com EtherLink III PCMCIA cards are equal. I got a 3C589D, the driver that comes with Rhapsody wants to see a 3C589. So here is my Network Devices window from the Configure.app: Clicking on "expert" brings up a new window where you can edit the driver... I changed the "PROD=3C589" to "PROD=3C589D". And that was about it. As for connecting beyond that, I set TCP/IP information by hand (including the DNS server address so I can see the internet). There are DHCP packages for Rhapsody (PPC) but as setting up the TCP/IP stuff wasn't that hard, I've never used any of them. Still, someone may be interested, so here is one package that I found a long time ago for Rhapsody PPC... Hope that helps out for any one needing this info.
