Well, I have the late 1.5 chip, I flashed it with m8 bios and tried xecuter2 bios and set the switches to theright bank "though dunno that the 4th switch does." and attached everything the solderless way. But when i turn on the xbox. It acts like it's not even in there. Any answers for this and what is that cable for that connects from the dvd drive power to the chip for?
