Unknown Devices in Device Manager

If you upgrade your older FRED operating system to a newer OS (such as Windows 7) you may have discovered that there are some Unknown Devices in Device Manager. This is due to the fact that Windows 7 was released after these motherboards were released, and the manufacturer may not have created Windows 7 drivers for the board.

To determine which hardware/driver component is causing the conflict, open up Device Manager and double-click on the malfunctioning device. Select the Details tab and then the Hardware Ids from the dropdown options. Note the PCI\VEN_#&DEV_#. Enter this value into your favorite search engine and you should see results that reflect the type of device it's assigned to. ie. PCIVEN_11AB&DEV_6145 is assigned to a Marvell 61xx RAID Controller.

Determine which motherboard you have. If you're in Windows XP you can right-click on My Computer and select Details, or simply open up the side panel on the system and look at the motherboard. Once you've discovered your motherboard model number (and it's an ASUS board) you can find drivers via a search at http://support.asus.com. If your motherboard does not offer Windows 7 drivers, select Vista drivers instead.
