If you are interested in downloading the original source packages from which Puppy is created, URLs are given here. However, to understand how to compile them you should first read this page. Or, if all you want to do is compile the kernel, look at this page. Note that the kernel configuration file used to compile the Linux kernel used in your running Puppy, is to
