* Make the Gigabeat S bootloader a bit more interesting: it looks for the first firmware file it finds on the second partition and attempts to load it. Loading fails to get past the splash screen though.

Browse source 
* Make the main binary compile.
To send a firmware file, use mtp-sendfile. To update you'll need to delete the previous firmware file, as files are named sequentially and the first one is loaded.
