HELP somebudy could explain me the MOD-DMA ... pls

[nem]

I need help, could someone explain the diagram for the mod DMA, really very difficult for me to understand diagrams, I'm more looking at the pictures and someone explain to me step by step, I understand electronics and you can not commit no mistake ..

I searched for pictures of MOD DMA, but I really just found the diagram and photo of the plate, do not understand they mean at all the signs ..

When I made the dual bios mod was easy to see so many photos to make sure that the mod was doing everything correctly ..

Please someone who has done the mod DMA could upload photos and a clear step by step explanation .. even could make the first tutorial I have not seen any step by step tutorial on how to do it..

im spanish to my ingrish be worst... blame google traslate...

You do not need to perform this mod anymore. Just make the usual dual bios mod and use one of these bootloader bioses. You'll be able to boot Dreamshell OS directly from HDD or SD.

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..

sorry my inglish its not the best..

Blocks not only DMA, blocks all IDE interface, including PIO too.
Anyway, just use this mod - http://www.dc-swat.ru/blog/hardware/16.html and flash bioses from RC4.
