ABSTRACT:
The invention features a method and apparatus for use with a computer system having a memory and a bus (e.g., a PCI bus). The bus is monitored for detection of a bus cycle intended for a controller (e.g., a DMA controller) used to transfer data between a bus device and the memory. After detection, the bus device is used to claim the bus cycle and to emulate the response of the controller to the bus cycle.
