hi gozar,
thank ones again for giving attention
I have an Intel D845GVAD2 motherboard with integrated graphics and no other graphic card but i do have an pinnacle tvtuner card but that is also not in use nowadays

I am not trying to do something indifferent but i do want read-write access on my linux partition as user knoppix,till now i am able to write on my hard disk only when i login as root and that to after using the remount command each time but i want to have read-write access on my hard disk so as i can normally work in knoppix as i do in windows(creating files,directories saving my work on it). i am able to read but am unable even to create a file on disk and want your help doing it.
