Ok, I got everything (Ipod number is disk device 1, which is the result I got.)
The problem is backing up the apple firmware, and installing rockbox's bootloader. This is what I'm putting in Command Prompt (BTW: I have a Windows XP, and I have a video ipod)
Backing up firmware : C:\rockbox\ipodpatcher [disk device 1] -r bootpartition.bin.
(no luck)
Installing rockbox: C:\rockbox\ipodpatcher [disk device 1] -bootloader-ipodvideo.ipod
(unplugged ipod, went straight to original firmware. nothing.)
Im confused. I followed the installation manual, and nothing. please help. it will be appreciated
