Programing directly to the controller is just what I doing. I am now
puzzling on the software flow of UDMA transfer.
My process is like this:
send the LBA address==>select the device==>send the Write DMA command code
(CAh)==>check the status==>send data to the data register.
The LED that indicates the disk status kept lighting after the transfer
complete. What is wrong with it?
Thanks

   If you're using INT 13h, then either BIOS or the loadable driver for your
IDE contoller does this for you.

   I'm working on this--but without use of INT 13h, so I have to program
the IDE controllers directly...
