In Microsoft System Center Configuration Manager 2007, you specify the supported platforms of a driver in the SDMPackageXML property XML of the driver's SMS_Driver Server WMI Class object. The XML contains a node PlatformApplicabilityConditions to which you add PlatformApplicabilityCondition elements for each platform the driver supports.

Note

You should add only platforms that are listed in a SMS_SupportedPlatforms Server WMI Class object. Drivers can only be conditioned for major operating system releases, that is, it is not possible to target drivers at service packs.

Warning

The supported platforms portion of SDMPackageXML is the only part of the CI-XML schema that can be edited. You should not make changes to other parts of the XML.

The following XML demonstrates a driver that supports two platforms. For more information about the supported platforms schema, see Operating System Deployment Driver Supported Platforms Schema.

<PlatformApplicabilityConditions>
    <PlatformApplicabilityCondition DisplayName="All x64 Windows XP Professional" MaxVersion="5.20.9999.9999" MinVersion="5.20.3790.0" Name="Win NT" Platform="x64">
        <Query1>SELECT * FROM Win32_OperatingSystem WHERE BuildNumber = '3790' AND OSType=18 AND ProductType=1</Query1> 
        <Query2>SELECT * FROM Win32_Processor WHERE Architecture=9 AND DataWidth=64</Query2> 
        </PlatformApplicabilityCondition>
    <PlatformApplicabilityCondition DisplayName="All x86 Windows 2000" MaxVersion="5.00.9999.9999" MinVersion="5.00.0000.0" Name="Win NT" Platform="I386">
        <Query1>SELECT * FROM Win32_OperatingSystem WHERE BuildNumber = '2195' AND OSType=18 AND ServicePackMajorVersion >= 4</Query1> 
        <Query2>SELECT * FROM Win32_Processor WHERE Architecture=0</Query2> 
    </PlatformApplicabilityCondition>
</PlatformApplicabilityConditions>

To validate the platform applicability requirements, use the SMS_SupportedPlatforms Server WMI Class class Condition property for the required platform.

To specify the supported platforms for a driver

Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
Get the SMS_Driver Server WMI Class object for the driver. The driver is identified by the key property CI_ID. For information about getting objects by using a key property, see How to Read a Configuration Manager Object by Using Managed Code
Update the driver XML.
Commit the changes back to the SMS Provider.

Example

The following example method adds a supported platform to the driver that is identified by objDriver. For example, the following calling code adds Windows XP Professional x64 operating system to the driver objDriver list of supported platforms. You can get the details for a specific platform from its SMS_SupportedPlatforms object instance.

AddSupportedPlatform objDriver, "All x64 Windows XP Professional", "5.20.9999.9999","5.20.3790.0", "Win NT","x64", "SELECT * FROM Win32_OperatingSystem WHERE BuildNumber = 3790 AND OSType=18 AND ProductType=1", "SELECT * FROM Win32_Processor WHERE Architecture=9 AND DataWidth=64"

For information about calling the sample code, see Calling Configuration Manager Code Snippets.
