Hello,
Haswell motherboard(not Intels), windows7 OS.
(I will ask motherboard manufacturer support - but maybe I'll get quick answer here )
After updating to new uefi version, "Unknown device" appears which hardware ids are "ACPI\ACPI0012". All device drivers were fine before update(chipset, etc.), reinstalling chipset drivers didn't help. I suspect that this device could be because some new feature(xeon cpu feature?) was enabled after update.
What device hardware id ACPI\ACPI0012 represents ?
How do I find drivers for it ?
Thanks,
Vilius M.
