Can some explain these two steps in a little more detail:

2) Copy "Update_kindle2_user_screen_savers.bin" to the root of your Kindle2.


Is that I file I am creating? ok figured that part out and where is thr "root" of my K2

3) Change directories to the "system" folder.
How do I change the directories?

Thanks for any help... !
