Afer knoppix is running, either open a command line window and use the command netcardconfig or use the menu item in the Knoppix menu to configure the network card eth0.
I use this work-around on some of my boxen that hang this way. Unfortunately, if I do a manual config and select dhcp, they hang again Static IP works but requires a little more effort This typically happens on a system w/only one wired NIC - no wireless.

Has anyone dug a little deeper into this? Any way to use dhcp? I'm putting together a remastered CD and bootable USB fob for a friend who does a lot of Winxx rescue/recovery and it isn't always easy for him to know the subnet address in advance. For that matter, any way to figure _that_ out before the NIC has an IP address assigened?

Thanks,
