The latest BIOS for your system should be available from one of the following locations:

Motherboard Manufactured by Intel
Intel® Desktop Boards are supported by Intel and the latest BIOS should be available in Download Finder. Select your motherboard from the left-hand menu (typically under "Desktop Boards"). A list of downloads will be displayed. If available, one of the downloads will be the latest BIOS.

Non-Intel Manufactured Motherboard or System
Other companies, such as Asus* ^†or MSI* ^†, manufacture their own motherboards using Intel® chipsets. These manufacturers have their own BIOS; Intel does not make other companies' software available for download. You should contact your motherboard manufacturer for the latest available BIOS for your motherboard.

Note: If you have a pre-built, OEM (Original Equipment Manufacturer) system, such as Dell* ^†, IBM* ^†or Gateway* ^†, you should contact your OEM for the latest available BIOS for your system.
