Hi Folks,

here's the problem I'm struggling with:

I know, that the registers of primary IDE-Controller are mapped to the ports 1F0h-1F7h (Command-Blocks) and 3F6h (Control-Block). I also read the ATA-specs and found several registers.

Now, has anyone information about how the registers of the ATA(IDE)-Device are mapped to these Ports ?

I tried microcontroller-forums, google, the faqs, specs... but found nothing.

Please help me, Daniel
