What should I know if I want to use a CF card that supports the DMA function on a motherboard?

Category : Setup / Operation
If you want to install a CF card that supports the DMA function on a motherboard, please check that your onboard CF socket or CF-to-IDE adapter supports the DMA function. You can examine if the following signal pins are connected properly. If yes, the socket or the adapter does support DMA function.

1.Pin 21((DMARQ) of IDE <-> Pin43 (DMARQ) of CF connector
2.Pin 27(IORDY) of IDE <-> Pin42 (DSTROBE/DMARDY/IORDY) of CF
3.Pin 29(DMACK) of IDE <-> Pin44 (DMACK) of CF
