    HP Compaq dc7600 series and dx7200 series business desktops, and the HP xw4300 workstation. An HP CMI Software Provider SoftPaq is also available for legacy models and may be downloaded from HP.com.
  • Page 3: Benefits

    Recognizing the need for a better solution, HP has developed the HP Client Management Interface. HP CMI provides a zero-footprint, programmatic interface built on industry standards that systems management tools and custom management applications can access to gather inventory information, heath alerts, and manage BIOS configuration.
  • Page 4: Architecture

    N etwork Client Hardware HP Client Management Interface leverages WMI to surface management information directly from the hardware and system BIOS, and in doing so gains all the benefits associated with the WMI interface to management information. Component Object Model is a specification developed by Microsoft. It provides the framework for technologies such as ActiveX.
  • Page 5: Hardware Sensor Information

    The following table defines the basic set of services provided by HP CMI to support the surfacing of hardware sensor data to management applications.
  • Page 6: Hardware Configuration Options

    Hardware Configuration Options One of the most compelling features of HP CMI is the power to manipulate and change hardware configuration options in an open and adaptable manner. WMI provides a foundation for scriptable administration of operating system options that is well proven in the enterprise management community.
  • Page 7: Available Software Products

    HP Client Management Interface for legacy HP business computers. While the HP CMI Software Provider does not contain all the features and flexibility of native HP CMI support, the Software Provider allows IT managers to reap many of the same benefits exposed by HP CMI on their existing hardware infrastructure.
  • Page 8: Hp Client Manager

    BIOS configuration details from within the HP ProtectTools interface. This application utilizes the data-driven model used within HP CMI. Because HP CMI is designed to expose information in a consistent manner regardless of varying platform feature sets, BIOS Configuration is capable of supporting a wide range of features and platforms with minimal, if any, need to upgrade the application.
  • Page 9: Hp System Software Manager

    HP System Software Manager HP System Software Manager (SSM) is a valuable tool in the custom IT solution arsenal for managing HP client computers. HP SSM supports automation of software and BIOS updates, and an ability to report and modify BIOS settings through a text-based file format. Available later this year, SSM 2.0 will leverage HP CMI to provide BIOS configuration support to 32-bit and 64-bit versions of Windows in a manner familiar to users of the utility.

This property field is used by utilities such as HP BIOS Configuration for ProtectTools to filter elements that are not applicable to a given platform. A value of 1 indicates that attempts to modify this setting will require interactive acknowledgement during the next system startup.

In the event that multiple setting instances share the same Sequence value, or the value is NULL, the Path and Name information is used to determine order.

    “abc123”. Notice that this is a form of encoding, not encryption. These examples were presented in this manner to convey the simplicity in developing custom solutions based on HP CMI. However, in an enterprise environment you probably do not want to leave traces of the Setup Password credential scattered throughout your script files.
  • Page 23 "<kbd/>1E302E020304" HP Client Management Password Control HP Client Management Interface Password Control provides two modes of operation. Stand-alone, the component can be used to convert keyboard scan codes into password text strings through a dedicated UI and cut-and-paste into the tool or code being used to modify BIOS settings. The control also provides an interactive mode of operation, in which the control can be invoked through an automation interface within a calling script or management application.
