Thanks again for the input. I have loaded Rockbox into the root directory
(e260), as well as, loaded Rockbox Loader. When I push pwr on the player loads Rockbox. When I want Sansa firmware, I can hold the left (rew) button and then push pwr and on it comes on.
So far I don't know what it does or how to use it. I have downloaded the manual, but it isn't an easy read. One thing I do like is the ability to increase the size of the font. Right now, I'm only interested in music on my player and not games or video, so the Sansa firmware works better for me. After I learn more about Rockbox, I might change my mind.
