Detailed description for r20921: FS #9730?

(1/3) > >>

SacredTerror:
I've read through the flyspray page for FS #9730, but unfortunately most of the discussion is not understandable to me.  The last sentence in the comments indicates that instructions for this patch may never be available in the manual, so I was wondering if I may be able to receive some personal instructions regarding this. 

Personally, I haven't used the Apple Operating System since the Rockbox USB stack was implemented in current builds for the ipod.  I have no use for it and see no problem in getting rid of it.  I would much prefer the fastest start-up possible.  Is anyone willing to give me a more detailed description?

I'm sorry man, but your going to have to really hold my hand with this thing.  Seems like something I really don't want to mess up.  All I have to do is run ipodpatcher.exe and type these 3 lines:

ipodpatcher -rf apple_os.ipod
ipodpatcher -wf rockbox.ipod
ipodpatcher -a bootloader-ipodvideo.ipod

And save the apple_os.ipod file that will be created to the root directory, right?  Do I first have to uninstall the current bootloader that I'm using, or will it be overwritten?  And will this change my current method of updating (unzipping to the the root directory)?  Thanks very much for your help.

I'm no expert but I just went through this process myself (albeit in linux) five minutes ago, with apparent success. Here's how I understand it...

ipodpatcher -rf apple_os.ipod saves a backup of the apple firmware for later. You could put that in / or /.rockbox IF you want to be able to boot into it (with hold).
ipodpatcher -wf rockbox.ipod writes out rockbox to the bootloader area, (OSOS, whatever the heck that is). Apparently you don't need to do anything else to get this to work. I was expecting to have to do something with the bootloader, but it works with just that command...

If the bootloader sees a rockbox.ipod on disk (in root or .rockbox) it will load that BEFORE the one you wrote into OSOS (?) with ipodpatcher. So you should/could do this every time you upgrade your build in the future (for full effect make sure to delete rockbox.ipod from /.rockbox after unzipping a new build).

SacredTerror:
OK when I type in either of those commands ipodpatcher.exe shows a few lines of text, but before I can read what it says it closes (crashes?).  Is this supposed to happen?  I don't see any files being created from the first command.  And I'm a little worried to try deleting rockbox.ipod just to see if it worked.
