* William Herrin:
The pro/1000 does not need to generate an interrupt in order to start a DMA transfer? Can you refer me to some documents which explain in detail how a card on the bus sets up a DMA transfer?
Busmaster DMA does not generate an interrupt on the host CPU. The interrupt is used to trigger processing on the host CPU; it can be deferred until several frames have been written.
