just got a modded xbox and was supposed to come already flashed but it ain't . was told by the person to check out teamxecuter to see how. first thing is my cpu is only good for net surfing no cd rom drive or anything in it. next i bought Avalaunch v.0474 ,Evolution X v.3921, and Slayers EvoX Auto-Installer v.2.5 i thought one of these might have the thing called a bios but i guess they don't i tried to flash from all 3 and i get no bios update found halting dont have a clue what i need to do to start playing my xbox any help would be great thanks.
