now, you have the signed phoenix bios loader, you need to go to the E drive and in the apps folder make a folder named something like phoenixbios or pb or whatever you want to name it.
(E/apps/phoenixbios)
now extract the rar to a folder and copy your default.xbe from your c drive to your pc, and then once its on the pc, rename it to evoxdash.xbe. Re-upload it to the Cdrive once it has been renamed.
now take all the files in that phoenix bios loader and put them in the E/apps/phonixbios folder.
that should do it, reboot the xbox and then go to the launch menu->apps->phoenix bios loader
you will see a little animation of the phoenix logo (its ok, it only does it the first time unless you delete the *.lock file it creates after running it) and then it will throw a black screen with some weird stuff in the corners and then a dark screen of your dash and then the full dash.
now, put a cd in the game drive, run dvd game will probably be red
you gotta reload the phoenix bios loader to get it to not be red, but now you can use your original evox dash where you have to run signed programs (or if you want you can instlal the bios loader into the c drive so it uses the bios loader as the default and not evox), and boot to the bios loader when you want, and from there you can use in game reset, access the cd drive (to make backups of games), running unsigned code, and some other features im sure ive overlooked
