Upgrading systems without SCO IPX/SPX configured

If you do not actually have SCO IPX/SPX configured on your system, you should remove the /etc/ipx.d/NPSConfig file before installation. A default IPX/SPX configuration in this file (created if IPX/SPX configuration was deferred during a previous installation, but then was never actually configured) will cause installation problems (even in the case of a Fresh installation).
