Well, you don't really want to fiddle with physical addresses from
within userspace programs while running a protected-mode operating
system:-)

If you only want to know the type of IDE controller, and if your
hardware wasn't build during stone age, it's probably as simple as
reading the IDE controller's PCI device IDs. There's a libpci available
for Linux which helps you doing this (because there are different access
methods for accessing the PCI busses).

'lspci' for example uses it, probably parsing lspci's output is just
enough for your job...
