There is also a newer type of DMA called Ultra DMA, or sometimes called Bus Mastering. This new type of DMA allows devices to bypass DMA controller all together. This way devices can access system bus directly. Ultra DMA supports burst mode data transfer rates, which provides twice the speed of standard DMA performance.

Unfortunately, this method of determining support is not foolproof.
