I downloaded drivers from http://www.nvidia.com/object/linux_d..._1.0-7167.html and there is how-to-section.
I did all like they said but im having trouble to boot using init 3. If im not wrong, I should write "Init 3" in boot, but I CANT! Knoppix boots right to the some menu, where is Linux, Linux 2.4 and Linux 2.6 (not sure about those numbers) and when I press <tab> I get to the boot selection, where I get to choose boot from those three option. I useally use Linux (knoppix 3.7).

So, what should I do now? I tried with root but didnt help (you appear to be running x-server etc... please boot with Init 3 (run level 3)
