In case you are wondering, a Bus Master is responsible for directing data transfer between the CPU and other devices (also called I/O devices). This permits data to move between different parts of the PC without impacting the CPU. In other words, a Bus Master can help improve performance of your system, particularly if it is slow/old. Note: The default setting for the driver is DMA mode. You can turn off the DMA setting by running the VIA IDETool. You are here: VIA Bus Master IDE driver download 3.01.12
