WinDriver is a development toolkit that dramatically simplifies the difficult task of creating device drivers and hardware access applications. WinDriver includes a wizard and code generation features that automatically detect your hardware and generate the driver to access it from your application. The driver and application you develop using WinDriver is source code compatible across all supported operating systems ［1.7］。 The driver is binary compatible across Windows 7/Vista/Server 2008/Server 2003/XP/2000， and across Mac OS X 10.5.x–10.6.x （using unified binaries）。 Bus architecture support includes PCI/PCMCIA/CardBus/ISA/EISA/CompactPCI/PCI Express. PCMCIA is supported only on Windows 7/Vista/Server 2008/Server 2003/XP/2000. CardBus， ISA， and EISA are supported on Windows 7/Vista/Server 2008/Server 2003/XP/2000， Windows CE.NET， Windows Embedded CE v6.00， Windows Mobile 5.0/6.0， and Linux. WinDriver provides a complete solution for creating high-performance drivers. Don‘t let the size of this manual fool you. WinDriver makes developing device drivers an easy task that takes hours instead of months. Most of this manual deals with the features that WinDriver offers to the advanced user. However， most developers will find that reading this chapter and glancing through the DriverWizard and function reference chapters is all they need to successfully write their driver.
