Other Documentation You May Need

You may also have one or more of the following documents.

NOTE: Documentation updates are sometimes included with the system to describe changes to the system or software. Always read these updates before consulting any other documentation because the updates often contain information that supersedes the information in the other documents.

• Operating system documentation is included with the system if you ordered the operating system software from Dell. This documentation describes how to install (if necessary), configure, and use the operating system software.

• The HP OpenView Network Node Manager Special Edition User's Guide, which describes the features, requirements, installation, and basic operation of this optional server management software. Refer to the software's online help for information about the alert messages issued by the software.

• Documentation is included with any options you purchase separately from the system. This documentation includes information that you need to configure and install these options in your Dell computer.

• Technical information files—sometimes called "readme" files—may be installed on the hard-disk drive to provide last-minute updates about technical changes to the system or advanced technical reference material intended for experienced users or technicians.
