I'm sorry if this is the wrong board, but it seemed to have quite a few threads about the S.
I bought a MES60vk off of Ebay mainly to rockbox since the port seems to be almost complete. I fiddled around with the original firmware but was having problems with WMP not recognizing the player. So, I decided I'll go ahead and install Rockbox, but wanted to leave the original firmware, but there isn't any info about dual booting on the wiki. How do you do it?
