all architectures work differently.

man diskless(8)

that will give you the basics, and then you can figure out the rest
after that.  it is unfortunate that it is not documented
per-architecture yet, but that's what you get.  even within
architectures there are some differences, so this is perhaps the limit
of what can be documented.

in essence, all the parts one needs to know about are in that man page.
