Although the default values should be appropriate in most cases, you may change any of the available options to meet the requirements of your specific system. It is recommended that you use the HP Network Configuration Utility to update HP NC-Series adapter properties. However, if you choose to update the properties using the operating system's Device Manager, the following lists the properties that are available for your HP adapter. The properties that are available through the HP NCU will differ. See the online help file for NCU adapter property information.
