The D0 tells the xbox when to use the chip and when to not use the chip (grounded = on). The BT point is for the eject button which allows you to power off the chip (push eject to boot into MS dash). If you don't solder the BT point then the chip will ALWAYS be on.
Anyone feel free to correct me.
Yup, you are correct
