Is there an URL for your suggested techniques. Also, are you familiar
with Okuji's I/O port probing method (the `ioprobe DRIVE' builtin)?
It steps through the BIOS with a debugger, and discovers which I/O
ports are used during an INT 13 for the specified drive.
Perhaps you can use some of its ideas.
