Default Translate BIOS drive address (80h) to IO port address (1f0/a0)

I have a very basic question. Please, can gurus help me?

To address an IDE HDD using BIOS, we use drive address in DL
such as 80h, 81h and so on. --- BIOS address

On the other hand, to address the same drive using IO port,
we use address of IO port (such as 1f0h, 170h) and master/
slave slection (0a0h, 0b0h). --- ATA address

And everybody knows that 80h is not always 1f0h/a0h. They can
be asigned to different ports.

Now, where can I find the translation, or cross reference, table
between BIOS address and ATA address?

I have 80h here. I want to know the port address and master/
slave information.
I know that EnhancedBIOS INT13 AH48 returns DDE at 1ah if version 2,
but how about in the case of using older BIOSes?
Thanks in advance.

You could check the serial number in 8xh and xF0 to find who is who

Thanks Nick, but,,,,
How can I get the serial # in 8xh?
INT13 AH25 is the only one I know, however, it is NOT for general use.
IBM limits it only for PS1 and PS2.
Or, any other means to obtain serial than this?

BUT that allows for remapping of the drives?

Um,
I did not think about this.... old one has no remapping....
Good thought. I will go along with this idea.
Port addresses I'm including as "unknown" are 0e0 and 070. 1e8 and 168
are
somewhat de-facto standard. There may be more, but I give up for other
ones.

(in other words, does such a beast actually exists? EDD 1.1 is dated
1995...)

Yea, I deal with really old gears. Actually, the program is related to
HDD
sanitization; they are on retiring machines.
Thank you very much for the help, Antoine.
