Installation guidelines

Important: Before you install optional hardware devices, make sure that the server
is working correctly. Start the server, and make sure that the operating system
starts, if an operating system is installed, or that a 19990305 error code is
displayed, indicating that an operating system was not found but the server is
otherwise working correctly. If the server is not working correctly, see "Solving
Problems" in the Installation Guide for diagnostic information.
