If its your bios then you can buy a modchip and flash the bios....that would get it working AND you would be able to put games/movies/mp3s ect ect on your xbox....thats what i got,
120gb xecuter moded w/fan XBOX
with xmediaplayer(plays movies,mp3s and pics)
a lot of emulators ect ect ect and a lot more crap but im too lazy to write it out, it actually does everything i want it to do, even when the music is playing it has a visual thing like in winamp....so i guess it can be used as a carputer too
