In the Makefile that creates the kernel, you will find:

ENTRYPOINT=3D     __start=20

which tells the build system to use "__start" as the kernel entry point.

This label is in macppc/Locore.S.

The startup code calls routines in both the macppc and the powerpc=20
directories. We use routines from the powerpc directory when we are=20
dealing with aspects of the CPU and system that are common across all (or=
=20
many/most) PowerPC systems.

Take care,

Bill
