Eww,,, nforce2 sucks in linux. I had the misfortune in buying that godforsaken motherboard. I use it but it puts Nvidia in a bad light.
It's one thing to be pissy about using openning up the drivers for a high-end consumer-level 3d card to open source. But what makes them seriously think their is something to hide in the propriatory drivers for a slightly modified version of a commonly used ethernet card?
It's a modified REALTECH ethernet card. The cards were most computer stores have sales for buy 2 for 8 bucks each and we will throw the third one in for free... To bad they changed it enough to make it unuseable under the stock linux drivers and then made there own drivers, but made it illigal for Distros to include the drivers in their distrubution. Grrrr.
Anyways. Best bet is to download the drivers onto your windows partition then boot up with your knoppix cd and compile and install them. AFter you get that done upload the driver modual to a ftp server or a floppy disk or something and then boot up into windows and copy the file backdown to the ntfs partitions.
Of course if you use FAT32 partitions it makes this much easer.
Then after that you can just copy the nvnet module to your harddrive somehow, reboot back into knoppix, copy the file to /lib/modules/your kernel crap/proper/path/
the run depmod.
the modprobe nvnet.
then run the "ifup eth0" script, if knoppix uses that, OR set if up manually:
ifconfig eth0 you.ip.address
route add default gw your.gateway.address
cat "nameserver your.dns.server.address" >> /etc/resolv.conf
Then if that works (it should) then put all the commands you just did into a simple bash script, so that you can do all this stuff with one command.
