<header>Using DMA</header> Disable/enable the <i>using_dma</i> flag for this drive.<p> This option only works with a few combinations of drives and interfaces which support DMA and which are known to the IDE driver (and with all supported XT interfaces).<br> In particular, the Intel Triton chipset is supported for bus-mastered DMA operation with many drives (experimental).<p> It is also a good idea to use the <b>Transfer Mode</b> option in combination with to ensure that the drive itself is programmed for the best DMA mode.<p> Using DMA does not necessarily provide any improvement in throughput or system performance, but many folks swear by it. Your mileage may vary. <hr>
