The size of the PPC kernel image is too large for OpenFirmware to support. Consequently, network booting will fail, resulting in the following error message:
Please wait, loading kernel...

2. Run the following command:
setenv real-base 2000000
3. Boot into System Managment Services (SMS) with the command:
