I need time to do a TUT but heres a brief version for you
Put your mod chip in and transfer the audio signed pheonix bios loader
(you will need to copy xboxdash to pc (as a backup) and overwrite xboxdash on your xbox to a live version, needed to make this work)
(these are found in the usual places)
Follow instructions in the zip file to put the files in right places, take your mod out, reboot, put an audio cd in, select copy track (in instructions).
Flash bios, your done!
I know this is a bit comp but i am working on a tut!
But their is an easier way,
It will cost you a game to do.
You need to get 007 AUF ( can be bought as a classic release for 20 quid).
use your mod to transfer 007 auf with evox file ( also in the usual places ).
Remove your mod and boot.
Run 007 and load the save.
Evo-x will load, Flash bios!
Done!
I would suggest putting the latest version of D6 bios into the bios folder of the file you are going to use.
By the way this can be done using any version xbox and any modchip!
Hope you can use this!
Cheers!
