Abstract
A method for the high-speed transfer of data between an IBM compatible personal computer (PC) and a bus device. A DMA controller is placed on the bus device to by-pass the PC's DMA controller. High-level terminate and stay resident software on the PC uses a combination of the DMA controller on the bus device and low level DMA controller routines to transfer the data between the PC and the bus device.
