LOL? I don't understand...
I don't see how any of those cases are necessarily hard to visualize.
Case 1: Typical PC with IDE as function of southbridge.
pci0 | -- 07.2 (IDE controller) | --- disk0 | --- disk1
Case 2: Promise IDE Controller with 2 channels
pci0 | --- 03.0 (Promise IDE Controller) | --- channel0 | ---- disk0 | ---- disk1
Case 3: Quad channel DEC Bridge
Ok, maybe I don't understand completely what you're talking about, Andre. That's just a 4 channel IDE controller, that happens to be on the board? So, it's looks the same as the last example.
Unless, I'm missing something, which is always likely.
