I have an xbox with a X3 CE chip installed with the attached bank switches. I was able to update to flashbios 3.0.1.
Bank 1234: on on off off
This xbox does not get passed the Xecuter boot screen when I short press the power button (chip enabled). If I long press the power button (chip disabled) I get code 13. If I long press the power button with an original xbox game in the DVD drive the game runs no issues. I am also able to reach the flashBios screen by long pressing the eject an power buttons together. I bought this xbox a while back and have been trying to make it work properly. I believe I'm missing another bios file but I'm really not sure. Any help or advice would be greatly appreciated.
