Clean re-install ov Vista - device manager indicates one unknown device - tried all three driver downloads from Vaio. Location is Intel(R) ICH8M LPC Interface Controller - 2815; Hardware IDs - SNY5001
On some systems I have found that it is the SMBus controller, but Vaio doesn't give the info required to resolve this. It might be the Sony Firmware Extension Parser, but again no sign of this on the Vaio website?
Many thanks for yr v fast reply - however on yr link the driver doesn't show for me??? Is there a way on the Vaio website to see additional drivers other than the 3 unrelated items that are shown? As you can see I did find it elsewhere,
