Installing Loader2 as the bootloader instead of the standard Rockbox bootloader is fairly easy. You don't even have to put iPodlinux on the iPod to do it.
You just download a precompiled "loader.bin" from iPodlinux's page (
http://ipodlinux.org/images/e/ef/Loader-2.4.zip), unzip and rename the loader.bin file as follows (taken from Rockbox installer wiki):
For iPod Color/Photo users - bootloader-color.bin, for iPod 4G (Grayscale) users - bootloader-4g.bin, for iPod Nano users - bootloader-nano.bin, for iPod Video/5G users - bootloader-video.bin, for iPod Mini 1G users - bootloader-mini1g.bin, for iPod Mini 2G users - bootloader-mini2g.bin and for iPod 3G users - bootloader-3g.bin
You then follow the standard Rockbox install instructions, adding a step at the end where you save a text file called ipodloader.conf in the root directory of the ipod that reads as follows:
timeout = 15
default = 1
Rockbox @ (hd0,1)/ROCKBO~1.IPO
Apple OS @ ramimg
Sleep @ standby
Disk Mode @ diskmode
If you want to boot to AppleOS as default, you change the line reading "default = 1" to "default = 2".
Then extract the .rockbox folder and rockbox.ipod firmware file to the root directory of the iPod.
Is this worth adding to the installer wiki? Or would it just be unsupported and as such not worth adding?
