You really don'y need the PIC or the Code to do this. Just follow the directions below the code. Turning the X2 off after you turn on the Xbox is not that hard to do. It just takes a few times before you learn when to do it. After that, its easy to repeat.
Just remember to use a boot CD or have Evox on your hard drive in a place the EvoxMatrixTSOP bios can find it. Slayer's 2.0 disk works great for this, Just flash the TSOP with the Bios on his disk, then you can copy a different Bios to your harddrive and flash that.
