Attached is an unofficial version of the driver that has two new registry parameters: 1. PCI9656DmaDisable - if nonzero, the driver doesn't touch the PCI9656's DMA registers and doesn't enable the DMA interrupts. ADMXRC2_GetCardInfo() will indicate 0 DMA channels. Attempts to use the DMA functions in the API will return a "not supported" error. 2. PCI9656RegsAsSpace - if nonzero, the base PCI address of the PCI9656 registers can be obtained by calling ADMXRC2_GetSpaceInfo() with an index of 2. Note that the LocalSize member of the returned structure is zero, because these registers aren't visible on the local bus (well, they are if you make the FPGA become a local bus master, but that's a very application-specific way to access them). These keys affect only PCI9656-based models, as their names suggest. These features will be present in future official releases of the driver, but are disabled by the default in the .INF file. So feel free to make a customized version of the driver by modifying the .INF file and then putting it back into the .ZIP file. regards Tomas
