Win7 quick start file system DMA mode to facilitate direct access to data

I believe many people do not know what DMA mode, in fact, we do not need to understand too much DMA, we only need to know the benefits of opening DMA under Win7 system is It allows the PC to directly access the data on the hard drive, but does not take up too much CPU time. Users can turn it on if they have this requirement. Of course, if you want to start DMA mode, the CD-ROM and hard disk on your computer should support the corresponding functions.

The specific opening method is as follows:

First, in the desktop "Start" menu, open the "Control Panel" window, and then click on the control panel, click “ Security "-“System", then click on the <quo;Device Manager” in the left pane on the system panel.

Second, then on the Win7 system device manager panel, expand the "hard disk controller" or "CD-ROM", and then switch to the "driver" tab In the middle, click the "Properties" button below, then you can set and select the DMA checkbox.

The above is the method of quickly opening DMA mode under Win7. Under normal circumstances, as long as your computer supports DMA mode, it is recommended to turn it on, which can save you a lot of time.
