Before calling for help

If your problem is not discussed in Chapter 3, ``Troubleshooting the installation'', and you cannot isolate the problem using ``Solving undocumented installation problems'', call your support provider for help. Before calling, however, make a copy of the following trouble report forms and your installation checklist from ``Installation and upgrade checklist''. Then, write down the critical information about your system, including a description of your problem and system configuration, so that the support personnel can analyze your problem quickly.
