I could not get this to install correctly. I run Windows XP SP3 with all updates from Microsoft. I downloaded every driver package they had on Promise website and none would install correctly. I have been a computer tech for 40 years and I do not understand how anyone can have a product in this day and age that requires a floppy drive to install the drivers from included CD.All I want to do is hook up a new SATA CD/DVD drive to my Dell computer which only has 2 SATA ports. This card will not even recognize any CD drives. For this price and hassle I give this one a definate thumbs down.
