A long list of questions for the experts of the board!

So then I'm gonna assume the matrix is the better chip then? Also I've heard the matrix really doens't work on v1.2 xbox due to the motherboard being different than the other xboxes but I dunno if it's true so if anybody has any information it would really be appreicated and I'm also gonna assume (stupid of me to assume since it's probably true, hell it's gotta be) that the matrix bios can be upgraded to by-pass the media check?
