For all those who can't get pp right:
Edit your TOOLS\kitchen_build_rom.bat and find the line with implantxip and replace it with those two lines:
..\TOOLS\osnbtool -ap xip.bin %pp%MB -y
..\TOOLS\implantxip -xip xip.bin -payload OS.nb.payload -imgstart %imgstart% -%uldr% -%nocert%
Of course you have to have osnbtool.exe in your tools directory
