linux distribution

hey there,
does anyone know a good, lightweight liunx distribution i can dualboot on my laptop to acces internet, mp3s etc. really fast. like in a couple of seconds? some new motherboards seem to have a feature like that if you can't really understand what i mean (my english is not very good sorry

maybe there is a distrbution that doesn't come with the usual load of standardsoftware?
just the bare os?
