I don't know all the details. This is how I understand the situation:
Basically the "boot ROM" expects a HFS partition and a System Folder
containing both (fake) Finder and System binaries.
There are different approaches to boot Linux.
miBoot just provides a fake Finder file and a System binary, which
actually reflects the miBoot boot loader. It is directly run from a HFS
partition without the need of MacOS at all.
This is the way I use since I try to use MacOS at least as possible.
Then there are BootX and MkLinux Booter, which are MacOS applications.
They can act as a Extension so they are run early during the boot phase
of MacOS or as a standalone application which is run from the desktop.
AFAIR there are more details at penguinppc.org -- though it's currently
