Solved Part # needed for Marvell 91xx Config ATA Device

April 6, 2019 at 02:40:48
Specs: Windows 7
I need the driver for the Marvell 91xx Config ATA Device running under Windows 7.

The Marvell site is at:

The site asks for the platform and the part number. Platform: Windows 7 64bit. No problem. Part Number: There are 27 part numbers! The first part number gives me about 30 different drivers! When I look in the Device manager, it gives me all sorts of wonderful information about the device but no part number. How do I find the part number for this device?

When I enter Platform: "Windows 7 64bit" the Marvell site gives me three drivers. I tried the one described as being for Windows 7 but Windows won't accept it as the appropriate driver nor will Windows accept the other two drivers. I could download hundreds of drivers and let Windows pick the one it likes but it would be far simpler to find the part number for the device. WHY DO THEY MAKE THIS SO DIFFICULT!?

And no, Windows will not search the internet for the appropriate driver. I tried that as my first action in the matter and Windows finds no suitable driver.

You should be going to the website of your motherboard's manufacturer rather than Marvell to find the appropriate driver.

It's not that difficult. It's no different than needing a part for your car, refrigerator, washer, etc, etc. But to be able to locate the correct part, you'll need the exact make/model/model number of the device you're working with.

As ijack alluded to, if the Marvell chipset is part of the motherboard, you'll need to know the make/model of your board, then you should be able to download the drivers from the motherboard manufacturer's website. If the motherboard is part of an OEM system (Acer, Dell, HP, etc), you will have to know the model/model number of the PC. Once you have that, you should be able to download the drivers from the OEM manufacturer's website. OR, if you have a Marvell based ATA controller card, you would have to know the make/model/model number of the card & then you should be able to download the drivers from the card manufacturer's website.

If you'll post the make/model/model number of what you have, one of us should be able to point you to the exact driver you need.

Thanks to ijack and riider for explaining how it works. Many thanks! :)

I actually found the correct driver from the Gigabyte MB site even though I am using an Asus MB. That makes sense in the context of your explanations: Asus and Gigabyte are probably using the same chip on the relevant part of their boards, so the same driver works on both.

I learned something new today. Thanks guys! :)

As per #13 above. The designer of the chip (Marvel) provides a reference driver based on the capabilities of the chip. The MB manufacturer then decides which features to use and how to implement them. So, the drivers you downloaded may or may not be exactly the same as the drivers available from Asus.

Always best to go to the manufacturer's site first for drivers.
