Chris and I are refering to the way that the UNIX kernel calls
ROM routines.  We only call one Apple ROM routine and that is
to either shutdown the machine or reboot it.

You are refering to the way the booter loads the kernel into memory and
executes it.  You are correct in your analysis of how the booter works,
except you forgot the part about "harry our friend"(silly little comment
in the code).

> btw, is it possible to get source to the booter at all? 
Not yet.

On a completely unrelated topic:
Does anyone know for sure if a Sparc 630MP running SunOS4.1.3 supports
a generic SCSI driver?
