The boot loading process and the * MODULE mark are described in Chapter 14 'Building and maintenance tools' in the pdf file 'PO.Applications'. Not all the tools are included - presumably their exact nature would depend on what system you are using for cross-development.

The 'Instructions' link gives you step-by-step instructions on how to get started.
