Use native operating system support whenever possible. If native support for the related feature is provided under a preinstalled version of Windows 98/Me or Windows XP/Windows 2000, comply with the related industry specification, create drivers based on Windows DDK guidelines, and meet the design requirements defined in PC 2001 System Design Guide or Hardware Design Guide Version 3.0 for Microsoft Windows 2000 Server.
For example, if the graphics adapter or monitor supports a digital video interface and is included on a system with Windows Me preinstalled, the implementation must follow the PC 2001 guidelines. Similarly, if the system supports IEEE 1394b and comes with Windows XP, comply with the industry specification, implement WDM minidriver support as defined in the Windows DDK, and follow the PC 2001 guidelines.

Follow the DDK and industry standards to ensure an upgrade path. If the feature is not supported natively in the preinstalled Windows operating system, comply with the related industry specification (if industry standards have been developed), follow Windows DDK guidelines for related bus and device class driver implementations, follow general Plug and Play and power management guidelines as defined in the Windows DDK, and plan an upgrade path for end users.
For example, if you design a system to include a new wireless technology for which there is no native operating system support, you must still use the related Windows driver model for adding support. In this example, driver support must be implemented as a Network Driver Interface Specification (NDIS) 5.0 miniport, as defined in the Windows DDK and cited in the guidelines for wireless devices in PC 2001 System Design Guide.
