Assuming this is the same AHCI controller (probably is, because I only see one mentioned in your logs), I think Win7 moved it from where BIOS left it. It probably started at 0xff970000, and Win7 moved it into one of the host bridge windows (but not the legacy VGA one): pci_root PNP0A03:00: host bridge window [mem 0xff980800-0xff980bff] pci_root PNP0A03:00: host bridge window [mem 0xff97c000-0xff97ffff] pci 0000:00:1f.2: no compatible bridge window for [mem 0xff970000-0xff9707ff] Bjorn -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
