About DMA
DMA (Direct Memory Access) is a method that transfers data between
various peripheral devices (e.g., a hard drive, CD-R/RW drive, etc.) and the
computer’s memory without using the CPU.
By checking the “DMA” check box, the transmission speed of data will
become high-speed. Furthermore, by decreasing the CPU load, the
processing speed of the computer systems is increased.
