To use the pre-Phase 2 binaries: upload P2.upg.tar.Z in binary mode to /tmp/P2.upg.tar.Z extract the files: cd / zcat /tmp/P2.upg.tar |tar xvf - rebuild the bootstrap area: bosboot -d /dev/hdisk0 -a reboot The file /usr/lpp/bos/README.N40.2 gives an outline of the fixed binaries. Note that these binaries are made available before full integration testing has taken place.
