I've already wasted *much* time trying to netboot. I had a self-built
2.4 kernel and I managed to load it via dhcp/tftp. OF could init
text and data segments but failed on bss. The necessary setup is
probably still working, I have just installed a new x86 based machine
via netboot....
Is there some howto (besides the one from the bsd folks) for what
settings are needed on my ancient OF version?

Is miboot open source? What would be needed for compiling it on a debian
tool-chain? Just a rewrite of assembler syntax plus some linker scripts?
What is codewarrior? Assembler or some high-level language?

Is this the first sector on your boot disk?
Is there a documentation of the firmware on what traps are available and
what they do?

Thanks.
