I couldn't think of any other place to put this, so if it in the wrong section, please forgive me.
So I am wondering, on the basis of the development to customize boot loaders and load the Rockbox OS, would it be possible to load other operating systems on such devices which have supporting hardware. Such as a small version of linux, minimal versions of windows xp, etc.
I am interested in building off of current Rockbox builds to create and successfully install a completely new OS on the Gigabeat S, however, I am not sure if it would be possible.
