yes you need a hacked bios to install a new dashboard such as evox....in order to use a hacked bios you must either have a modchip, or softmod your xbox
cuz im getting the new X3 with cromwell installed on the Memory banks. was wondering if you could keep the cromwell(or if there is a better one then that one)and install Evo X on it, or does i have to have an evoX BIOS to install Evo X dash
you will need the X3_1959 bios...after you have flashed your chip with this bios... then you can use the slayers disc to install evox
