Need some help with Gigabit Network setup

I am a linux newbie, so be patient ;-)
On Suggestion i use Knoppix Live CD, for to become familiar with linux.
I have an onboard gigabit Lan using a Asus A7NV8X mainboard. My Lan was
not recognised so i used modconf and tried network device "e1000". Then
i was asked for a "Kommandozeilen-Argument" (german). I dont know wthat
that is, or where i get it. Leaving this form blank does not work. I
hope someone can help me :-)

Thanks for your help.
