Use the iL_hybrid drivers and use make. Then insmod il.o. You may have to use the -f tag to force it to use it. Then type netcardconfig, and say yes to dhcp. It should work now.

You don't have to do a hard-drive install to use the HPNA with knoppix. But you need somewhere to save the il.o file so you can use it later, unless you want to compile it every time.

Knoppix works very well with HPNA.
