trolly 1db510e6a9 modified kernel from the standard kernel
it load the first app (or vrr_m) and cpu from /hd0/1/kolibri/bin

the skin is in /hd0/1/kolibri/etc/default.skn
the drivers ar loaded from /hd0/1/kolibri/drivers

the ramdisk is'nt loaded when you chose to load it from the hard-drive (because it is'nt needed)

you will also need to download the modified version of sommes app:

launcher
vrr_m
@panel 
@menu
setup
icon
jpegview
@rb
