You can’t really do anything with just a kernel so what exactly are you trying to do ?

Yup, more info required.

What are you trying to do, and in Which OS ?

Gonna guess at configuring & compiling your own kernel, or getting the source code to hack & patch it?

Either way, info on compiling your own is here - https://help.ubuntu.com/community/Kernel/Compile
Info on getting the source code is here - Kernel/SourceCode - Ubuntu Wiki
Loads of kernel hacking information is here - http://linuxdocs.org/HOWTOs/Kernel-HOWTO.html
