Hi all,
Does anyone know how to use the pci bus-mastering feature to implement dma transfers from/to hd-drive?
I've read the various ATA standards and the "Programming Interface for Bus Master IDE Controller Revision 1.0" and I tried to implement these specs but my code doesn't work.

Has anyone info or doc link please?

Thanks.

Well,

thanks again but I've already visited all the link on the posted site... There's nothing specific on bus-mastering and on how to program it!

Is there anyone who has some experience with it on the forum?

Thanks all,

Raist
