-=The very first time you flash it=-
Once you ave got the bios, you will most likely need to connect the programmer to the xodus chip and connect the programmer to you pc's printer port. You may or may not get specialized software with the chip where you will find your chosen bios and the software will transfer the bios to the chip. Remove the programmer from the modchip and install it inside the xbox.
Once youve done this for the first time you should be able to flash the chip via other methods not using the programmer.
Its all still up in the air untill the xodus team release specific instructions. IE what the 2 switches do. You might have to have the modchip on the motheboard at the time. It may or may not be a more complicated method. Nothing you cant handle though
. Its a newb friendly modchip.
