How to build Kernel

1. Check out NetBSD-current src tree @ 2003/06/10.

       # cd /usr
       # cvs -d :pserver:anoncvs@anoncvs.netbsd.org:/cvsroot longin
       (use password "anoncvs")
       # cvs checkout -P -d -D2003/06/10 src
       

2. Update ONLY the following files to HEAD.
   • sys/arch/powerpc/ibm4xx/cpu.c
   • sys/arch/powerpc/include/ibm4xx/cpu.h

       # cd /usr/src/sys/arch/powerpc
       # cvs -d :pserver:anoncvs@anoncvs.netbsd.org:/cvsroot update -A ibm4xx/cpu.c
       # cvs -d :pserver:anoncvs@anoncvs.netbsd.org:/cvsroot update -A include/cpu.h
       

3. Apply Kernel pacthes

       # cd /usr/src/sys
       # patch -p0 < /somewhere/patch-obs266.arch.evbppc.diff
       # patch -p0 < /somewhere/patch-obs266new.arch.evbppc.diff
       # patch -p0 < /somewhere/patch-ibm405gpr.arch.powerpc.diff
       # patch -p0 < /somewhere/patch-ibm405iic.arch.powerpc.diff
       # patch -p0 < /somewhere/patch-ibm405iicnew.arch.powerpc.diff
       # patch -p0 < /somewhere/patch-hpt371.dev.pci.diff
       

4. Build kernel: Kernel config file = OPENBLOCKS266

       # /usr/src
       # ./build -m evbppc kernel=OPENBLOCKS266
