For some reason, Windows XP sometimes uses PIO parallel input and output transfer mode on the IDE channel instead of DMA mode. If this is the case, you can manually change the IDE channel to DMA mode, which can reduce the CPU cycles occupied by the device. Open the Device Manager (right-click My Computer, select Properties, click the Hardware tab, click "Device Manager" to open), then click to expand the "IDE ATA/ATAPI Controller" branch, double-click " PR imary IDE Channel", Click Advanced settings. Check the "Transfer Mode" drop-down menu, set them all to DMA If Available (use DMA if allowed), and click OK. Then modify each IDE controller in the same way
