Hello. I've done some searching on my problem but I still can't resolve it. First let me tell you my hardware

Computer = Dell 3000 http://support.dell.com/support/edocs/systems/dim3000/
Video Card = Intel 82865G Graphics Controller

When it boots up i get something about unidentified modes. I have tried

knoppix screen=1024x768
knoppix screen=800x600
knoppix vga=scan
knoppix vga=0x317
knoppix vga=normal
failsafe

And after that I still only get 640x480 resolution when X-Windows starts.
