What would be the difference between a HPT370-enabled motherboard and another board with simply an additional IDE controller on it? There is surely some hardware component present, as when the system boots up you can hit ctrl-S I think it is to build your raid arrays and examine the disks. Perhaps I'm oversimplifying, but I insist on drawing a distinction between a HPT370 controller and simply adding another standard IDE controller. Maybe I'm missing your point, but while the HPT370 can indeed just work in "normal" additional IDE controller mode, it presents to the system in raid configuraton a device that apparently can't be seen without special drivers. This seems to put it squarely in a class of hardware-based implementation to me. I've heard the same criticism of the Promise raid solutions- are they too manufactured by HPT? Please educate me. Thanks!
