Can anyone recommend a detailed reference of specifications of the signals on a pc AT compatible expansion bus for DMA BUS Master interfacing techniques. I have the technical reference manual but, only general signal desriptions are covered. I need to know how to decode REFRESH so I don't conflict with memory refresh cycle. Are there any good books or sources of timing diagrams available? Please email any responses.
