Im not sure if ths belongs here but it seems more like a bios question then Tsop or i guess it could be both but anyways. I have a xbox with a Xenium Ice chip. ITs been running fine but after i installed the Halo 2 map pack The retail Bios doesnt load the xbox boots then reboots the hacked bios. Hacked bios works fine its just the retail bios that does not boot. I have an image of the retail bios for the box could i do the tsop flash for the xbox without using a hacked bios to re flash the origional? Before you say oh thats what you get for downloading games THis is the Legit copy of the map pack......
