Lionel, as you already figured out, looking at the northbridge IDs is simply not sufficient to find out which capabilities and register layout the IDE controller in the southbridge (no matter if integrated or external) has. Some comments: 1) the 745 has an integrated southbridge and an ATA/100 capable IDE controller 2) the 646 (and most likely the 645 and others as well) may be paired with a 961 (ATA/100) or 961B (ATA133) MutIOL southbridge with different register programming values. Thus simply ripping out some northbridge IDs wouldn't prevent corruption problems.
