Need more help

How can I boot up a backup without a modchip??? I tried 2 ways I read and they didn't work. I really don't want to go through the pain of ordering it, finding someone who can solder, having that person do it, etc... I have looked at millions of sites (well, not millions) about burning. I have gotten the most help here.
Also, how can I burn PS2, xbox, and Gamecube games?? How can I use them without a modchip?? Whatever info you got, please tell me.
One last thing, can I use a DVD-R to burn music onto?? If so, is there anything special to know and how much music can I fit on it?
