Sorry, maybe I'm not clear.
I'm asking about the differences between the dual boot with loader.bin  and rockbox bootloader-video.bin .
That's my doubt.
bootloader-video.bin gives me the original OS holding MENU while rebooting.
loader.bin gives me a menu with options Rockbox and Apple OS.
I can access Apple and Rockbox firmwares with both methods.
So, what's the difference using loader.bin or bootloader-video.bin ?? Any advantage??
