This document provides installation instructions for the options available for updating your computer to the latest BIOS version.

To identify your current BIOS version, check the BIOS version string:

1. During boot, enter the BIOS setup by pressing F2.
2. Check the Main menu.
3. The 4-digit number after the '86A' or '86I' is the current BIOS version, as in this example: MQ96510H.86A.1663.2007.0319.1957
4. Press Escape to exit BIOS Setup.

Important:

• Update the BIOS on your computer only if the newer BIOS version specifically solves a problem you have. We do not recommend BIOS updates for computers that do not need it. You can view all new BIOS fixes in the Release Notes included on the BIOS download page in Download Center.
• Before initiating a BIOS update, be sure to read and precisely follow the update instructions. You may wish to print the instructions for easy reference.
• If a BIOS update process is interrupted, your computer may not function properly. We recommend the process be done in an environment with a steady power supply (preferably with UPS).
• All images in the examples used in the instructions are specific to certain desktop boards and are for illustration purposes only. You need to select the correct BIOS files for your desktop board.

There are up to six methods of updating an Intel® Desktop Board BIOS to the latest version. The number of options made available for any particular board may vary, depending on drive support and BIOS update file size. You only need to use one.

All BIOS update files for Intel® Desktop Boards are available on Intel's Download Center.

² The floppy disk methods may be used only when the BIOS update files are small enough to fit on a floppy disk (smaller than 1.44MB) and if the desktop board includes floppy drive support.

³ The F7 BIOS Flash Update is available on Intel® Desktop Boards beginning in 2009.  To see if your board supports this feature, in BIOS Setup, check the Advanced > Boot Configuration menu for the setting Display F7 to Update BIOS.
