I just bought a new xbox so I could put a mod chip in. I was looking to buy this mod chip. http://www.kanection.co.uk/product.php/217/27//940a85326633a72cff6255dfa2a77ed0 It is a Xecuter 2.2 Lite Plus Mod Chip. When I buy this and put it in, do i need to install any new software? or can i just install and start playing? and also i need to know what does it mean when i need to flash my bios? or reflash my bios? and how would i do this? Please help!!!!!
