In the unlikely event that a BIOS update is interrupted, it is possible the BIOS may be left in an unusable state. The recovery process requires the chassis to be opened to move the onboard BIOS Configuration Jumper.
Use this method if the recovery file (*.BIO) is too large to fit on a diskette or if the desktop board does not include diskette drive support.
Download and save the Recovery BIOS file to a temporary directory.
Copy the recovery file (*.BIO) to a CD.
Place the CD in the CD-ROM drive of the target computer.
Shut down the computer and unplug the AC power adapter.
Open the chassis and remove the BIOS Configuration Jumper (Image 1 below). See the Technical Product Specification for details including the location of this jumper.

Power the computer on.
Wait 2-5 minutes for the update to complete.
The computer will either turn off when the recovery process is completed or it will prompt you to turn it off.
Replace the BIOS Configuration Jumper (Image 2 above).
Close the chassis.
Restart the computer.
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 BIOS changes in the Release Notes included on the BIOS download page in Download Center.
Downgrading the BIOS to an earlier version is not recommended and may not be supported. An earlier BIOS version may not contain the support for the latest processors, bug fixes, critical security updates, or support the latest board revisions currently being manufactured.
Before initiating a BIOS update, be sure to read and precisely follow the instructions included in this document. 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).
Before updating the BIOS on the Intel® Desktop Board, manually record all BIOS settings that have been changed (from default) so they can be restored after completing the BIOS update.
All images in this example are for illustration purposes only. You need to select the correct BIOS files for your board.
