I don't know what you meant about "DMA" here.

Til i know the default transfer mode of HDD mod be just PIO mode, these squematics be like i do undestand to unlock the DMA mode (Direct Access Memory) more faster and with more compatibility than mode pio.. but this is the point the games will run faster and many more games now will work..
