Except ICH6 Intel uses separate IDs for AHCI and non-AHCI SATA controller modes. So this flag is not completely correct. But probably it shoudn't be just removed, as it is checked in other place. I know about this and going to handle it later. It's not a problem now. > Regarding the "dual device IDs": what this means is that ports 0-3 are > tied to one device on the PCI bus, and ports 4-5 are tied to another > device on the PCI bus.
