We ran support pack 5 on a netware 6.0 server and it hung on a
hardware driver and would not go further than 16% complete. After
shutting down the server it now as expected will not load and abends
on nwserver.nlm. During the support pack install we chose to backup
the files. Does anyone know how to either finish the installation of
this sp5 and or revert back to sp4.

We have tried to reinstall the upgrade booting to the sp5 overlay but
that is not working. We get the error that this server is already
running nw6.
