I applied the patch by hand, and it now works. Thank you! I can see ndis0 and connect using dhclient. Did I say "thank you" yet? By the way, I just got back from a business trip and finally got to test your patches for the pccard issues. I borrowed a wireless card, and it worked great. Of course, now that I've applied your fix for ndis I no longer need your patch for the pccard! :-) Thank you again!!!
