PM55 driver, Device unknown Win8/64

Hey Intel

I recently installed windows 8 on my Sony Vaio VPCF12Z1E/BI.

In device manager there is one onknown device.

I tried using Intels system identification utility, below is the result:

Trying to use the Chipset identification utility is no luck for me as im on 64-bit windows.

Doing a search on "PM55" gets me no hits when searching for drivers on intel.com.

i downloaded the Intel Chipset Driver 9.1.1.1025 from Sony´s site, listed under preinstalled items for Windows7. Its installes without problems, but the device still lists as unknown in my device manager.

Any help?

Best regards

Sune
