You can write once, and it will run on all of these platforms. No kernel or OS knowledge is required. WinDriver uses wizards to diagnose your hardware and automatically generate your driver code. It includes support for PLX, Altera, Cypress, QuickLogic, National Semiconductor, STMicroelectronics, Texas Instruments, Xilinx, PLDA, and AMCC chipsets. WinDriver also provides extended support for Windows Driver Model (WDM), Plug-and-Play, and Power Management. Version 6.2 supports Linux kernel 2.6 and adds an option to start developing your driver before your PCI hardware is available. IN A SIMPLE WAY IT GENERATE ANY DRIVER FOR YOU WITH ALL WINDOWS HAVE FUN -------------------------------------------------------- HERE IS THE WEBSITE LINK TO DOWNLOAD IT: http://download.com.com/3000-2383-10282273.html?tag=lst-0-1 --------------------------------------------------------- AND HERE IS THE SERIAL NUMBER: Removed --------------------------------------------------------- this program coast $2000 so use it waisly and any one have a solve for my proplem lps send it to me thank you
