	Direct memory access - Wikipedia, the free encyclopedia
		DMA is an essential feature of all modern computers, as it allows devices to transfer data without subjecting the CPU to a heavy overhead.
		For so-called "third party" DMA, as is normally used with the ISA bus, the transfer is performed by a DMA controller which is typically part of the motherboard chipset.
		A typical usage of DMA is copying a block of memory from system RAM to or from a buffer on the device.

	DMA
		Depending on the type of DMA transfer and the characteristics of the controller, a single pair of cycles may terminate to allow the CPU to run for a while, or a complete block of data may be moved without bringing the processor back from the land of the idle.
		Once the entire transfer is complete the DMA controller may quietly go to sleep, or it may restart the transfer when the I/O is ready for another block, or it may signal the processor that the action is complete.
		DMA was invented to move data between I/O and memory, but now people use it for a variety of other reasons as well.

	Direct Marketing Association (DMA)
		The DMA will not limit or restrict the offer of this service to the United States, but will accept subscriptions from any country and make the list available to both DMA members and non-members who commit to use the list solely to delete addresses from their e-mail promotion lists.
		The DMA has invited all other associations around the world to point consumers in their countries to this service, and to link their web-sites to the preference service site to enable all consumers, located anywhere, to subscribe quickly and easily.
		The DMA feels that at this stage of development of electronic commerce, resolution of many of these questions should await the experience of the market, the kind and degree of problems experienced and the reaction of businesses and associations to those problems.

	What is Direct Memory Access (DMA)? (Site not responding. Last check: 2007-09-20)
		The DMA can be configured to handle moving the collected data out of the peripheral module and into more useful memory locations (like arrays).
		The DMA is intended to be used in low power mode because it uses the same memory bus as the CPU and only one or the other can use the memory at the same time.
		If this is not done, the results of the DMA operation are âunpredictable.â Also, the behavior and settings of the DMA module should only be modified when the module is disabled.

	Ultra ATA FAQ
		DMA increases speed by using the DMA controller to manager the data transfer rather than the processor.
		The operating system must have a DMA capable driver installed before DMA can be used.
		Bus Mastering DMA allows the interface card, or drive controller, to manage the transfer of data from the drive directly to the system’s memory.

		There is no way for the user to enable DMA on these devices.
		The only option for the user who wants to enable DMA mode is to uninstall and reinstall the device.
		If the drop-down box already shows "DMA if Available" but the current transfer mode is PIO, then the user must toggle the settings.

	Fine Tuning Windows 98: Using DMA (Bus Mastering) - HelpWithWindows.com
		DMA (Direct Memory Access) mode of operation allows the DMA channels to handle data transfer so that it's not required for the CPU to monitor the transfer, thus reducing CPU overhead.
		It seems that when using this method (as opposed to buying a system which had DMA (properly) enabled by the OEM), an entry of the registry is not updated.
		If your drive does support a DMA multiple-word protocol and the DMA check box will not remain enabled, the IDE controller may not be compatible with the Microsoft IDE bus mastering driver.

	DMA
		It is important to understand that although the CPU always releases the bus to the DMA when the DMA makes the request, this action is invisible to both applications and the operating system, except for slight changes in the amount of time the processor takes to execute instructions when the DMA is active.
		Whenever a DMA channel is active, the contents of that latch are written to the address bus and kept there until the DMA operation for the channel ends.
		Once the DMA has moved the data into this buffer, the operating system will then copy the data from the buffer to the address where the data is really supposed to be stored.
