Technically you don't. The function is only available for use with the CR3 Pro & R-JTAG kits but it's not needed as the console will still boot without it but it's for those who wish to further tune up their install and reach optimum boot times. I'm still using v1.0 and which I didn't even buy but someone gave to me after they failed they failed their RGH install and passed it onto me to complete.
