This section summarizes the PC 98 requirements for video and broadcast components.
43. Device drivers and installation meet PC 98 requirements
Required
The manufacturer does not need to supply a driver for a device if the device passes PC 98 compliance testing using a driver provided with the operating system. If the manufacturer supplies a driver, then the requirements for the device drivers and installation are defined in the “Basic PC 98” chapter in Part 2 of this guide. The basic requirements include driver support for unattended installation and Help file support if special driver parameters are used.
All video components must use a WDM minidriver instead of a VfW driver. For PC 98, a VfW driver is not compliant with these requirements. For information about WDM driver support, see the Windows NT 5.0 DDK. See also the related articles at http://www.microsoft.com/hwdev/pcfuture/.
Drivers for hardware decoders and for the audio and video subsystems must be implemented as described in the Windows NT 5.0 DDK in order to support DirectShow, DirectDraw 5.0 VPE, and WDM.
44. Software drivers are installed during hardware driver installation
Required
Any additional required device-dependent software such as software codecs or NDIS transports must be installed during the device driver installation routine and must be included in the device INF file.
45. Applications provided with device meet Win32 requirements
Required
Recommended: Video and image editing applications bundled with the device should support DirectShow.
Any Windows-based applications provided with the device must meet software compatibility requirements as defined by the Win32 SDK. Applications installed with the device must use a standard Windows-based installation method as defined in the Win32 SDK.
