VistaFan

I recently upgraded from Win XP to Vista Ultimate. In device manager I can see the SIL 0680 IDE Controller with no error or problems reported in properties. However, when I go to Storage manager I do not see any of the two drives connected to the IDE Controller card???!! I have downloaded the latest driver from the Silicon Image support site - flashed the card with the latest BIOs. No Luck It was working fine under WinXP before the upgrade. Anyone have similar problem, and has found fix for it?
