No, the complete installation instructions of xenomai are in the file
"README.INSTALL" in Xenomai sources, here you are citing only one part
of it. But they assume you already know how to install Linux, which is
why the module installation is not detailed and we tell you "manually
install the kernel image, system map and modules to the proper location".

So, you should learn how to compile a custom version of the kernel for
your board, and when you know how to do that, following xenomai
installations will be easy.
