First; I wanna thanks to everybody who replied to this thread..
What did I do?;now I am gonna tell you?I think when the Knoppix installation over it has aproximately 2 GB in a HDD.I need this OS under 1 GB so tried to remove all packages that you told me. But removing all of them was not enough, so I oppened the www.inittab.com (as metovoid told me ) ;there is a MiniKnoppix and they also declared that which packages they removed.So I started to remove these packages one by one by hand:)) At last,finaly i reduce the installation from 2 gb to 1GB and (plus)150 MB but thats all:))Really....

:)) I need a value under 1 GB ....So decided to install this miniknoppix from beginning.=====>

Then I sucsessfuly install it.This miniknoppix uses Knoppix 3.3 but when with booting kernel 2.78 ??? my maouse doesn't work.I dont why!! but if I use kernel 2.6-2 that is not problem.....This is not end I have to install Mozilla on this machine(only the web browser) when I say apt-get install mozilla there is a error like this
(I don't remember exactly)

has no avaible version,but this package has already in the database but you dont have a candite to install this packages ) but somthing like that?

if I'll have chance i am gonne send the whole text....Do you have any idea?

Thanks for your consideration....
