Unlike Windows NT, the Windows CE implementation of NDIS does not support Direct Memory Access (DMA) operations inherently. Some platforms may provide DMA libraries for use by driver developers, or the miniport driver might need to implement DMA entirely on its own. In Windows NT, there are two methods to implement DMA, depending on whether the LAN is a subordinate DMA network adapter or a busmaster-DMA network adapter.
