And Windows does move it: the BIOS would have left it at just as when booting Linux, but Aida shows that it's now at FEAF8000-FEAFFFFF. Thanks, that's perfect! The Linux 00:04.0 notation indeed means bus 0, device 4, function 0, a Thermal Management Controller.

It seems that the PCI bus 0 device 4 is the If you happen to have Windows on this box, it would be very interesting to see what it does with the 00:04.0 device via Device Manager or something like Įnclosed is the Aida Extreme report. It's also conceivable that Windows notices the ACPI resource () that overlaps it and takes that into account. Microsoft Windows normally does the same thing, but where Linux uses the lowest unused space (0xdfa00000-0xdfa07fff in this case), Windows uses the highest unused space. Looks like a straightforward case of the BIOS leaving a device outside the host bridge apertures, and we're trying to fix it.
