Hello Dennis,
Did this controller come with your system or did you install it seperately?
If it came with your computer, then you will need to download the drivers from your manufacturer's web page.
If you purchased it seperately, you will need to get the drivers from Marvell's site:

You will need the part number to get the correct driver.
Let us know.
Best regards,
