thanks for the quick responses! one more question and i will leave you guys alone. how would i flash the mod chip? i am assuming i would have to dl the bios, but how would i get it onto the chip? again, sorry if its a dumb question, but i am new to the xbox. i will have pretty reliable help when doing all this but i just wanted to get an idea of how its gonna go down. thanks again!
