[printable .PDF version]

Note: PDF files require Adobe Acrobat Reader*

With the iFlash BIOS update utility you can update the BIOS from a USB device, diskette, or bootable CD-ROM. (Information on how to create a bootable USB device or CD is listed at the end of this document.)

See other BIOS update methods.

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

If Using a Bootable USB Device

You can use this method if the iFlash files are too large to fit on a diskette or if the desktop board does not include diskette drive support. You will need a bootable USB device, such as a USB thumb drive or USB external hard drive. (Information on how to create a bootable USB device is listed at the end of this document.)

Part 1: Create the bootable media (USB Device) containing the BIOS update

  1. Download and save the iFlash BIOS Update file to a temporary directory.
    save the iFlash BIOS Update

  2. Double-click the *.EXE to extract necessary files.

  3. Double-click the SW.EXE file to extract additional files.
    sw.exe location

  4. Copy IFLASH.EXE (or IFLASH2.EXE, depending on your board model) and the .BIO file to the bootable USB device.
    iflash.exe and .bio file location

  5. Configure the BIOS of the target computer to boot to the USB device:

    1. Press F2 during boot to enter BIOS Setup.

    2. Go to the Boot menu.

    3. Enable USB Boot.

    4. Save by pressing F10 and exit the BIOS Setup.

Part 2: Update the BIOS of the target computer

  1. Configure the BIOS of the target computer to boot to the USB device:

    1. Press F2 during boot to enter BIOS Setup.

    2. Go to the Boot menu.

    3. Enable USB Boot.

    4. Save by pressing F10 and exit the BIOS Setup.

  2. Boot the target computer with the USB device connected.

  3. At the prompt, type IFLASH /PF XXX.BIO , where XXX.BIO is the file name of the .BIO file (or IFLASH2 /PF XXX.BIO, depending on the version of iFlash you have) to launch the iFlash BIOS update process. Follow all prompts.

If Using a Diskette

You can use this method if the iFlash files are small enough to fit on a diskette and the desktop board includes diskette drive support. You will need a blank diskette.

Part 1: Create the bootable diskette containing the BIOS update

  1. Download and save the iFlash BIOS Update file to a temporary directory.
    save the iFlash BIOS Update

  2. Insert a blank diskette into the diskette drive.

  3. Double-click the *.EXE file to begin the iFlash BIOS update process. Press “y” to extract necessary files to the temporary directory.

  4. After the extract is complete, the following files will be present in the temporary directory:
    run.bat location

  5. Double-click the RUN.BAT file. Follow the prompts to create the bootable diskette.

Part 2: Update the BIOS of the target computer

  1. Boot the target computer with the diskette in the diskette drive. The BIOS update process will begin automatically.

  2. On the welcome screen, press any key to continue.
    welcome screen

  3. You’ll see the status of the BIOS update as shown here. DO NOT shutdown or power off the computer at any time during the update process.

If Using a Bootable CD-ROM

Use this method if the iFlash files are too large to fit on a floppy disk or if the desktop board does not include floppy drive support. You will need a bootable CD-ROM. (Information on how to create a bootable CD is listed at the end of this document.)

Part 1: Create the bootable media (CD) containing the BIOS update

  1. Download and save the iFlash BIOS update file to a temporary directory.
    save the iFlash BIOS Update
  2. Double-click the *.EXE to extract necessary files.

  3. Double-click the SW.EXE file to extract additional files.
    sw.exe location

  4. Copy the .BIO file and IFLASH.EXE (or IFLASH2.EXE, depending on your board model) to the bootable CD.
    iflash.exe and .bio location

Part 2: Update the BIOS of the target computer

  1. Configure the BIOS of the target computer to boot to the CD-ROM drive:

    1. Press F2 during boot to enter BIOS Setup.

    2. Go to the Boot menu.

    3. In Boot Device Priority, set the CD-ROM drive to be the first boot device.

    4. Save by pressing F10 and exit the BIOS Setup.

  2. Boot the target computer with the CD in the drive.

  3. At the prompt, type IFLASH /PF XXX.BIO , where XXX.BIO is the file name of the .BIO file (or IFLASH2 /PF XXX.BIO, depending on the version of iFlash you have) to launch the iFlash BIOS update process. Follow all prompts.

Creating a Bootable USB Device

Making a USB flash device into a bootable drive is not as simple as creating bootable floppy disks. Please refer to the documentation provided by the manufacturer of your USB device for information on how to create a bootable USB device. Additionally, you may refer to any of the following Web sites for tips on creating bootable USB devices. Intel is unable to assist with the creation of bootable devices.

You can also search for additional resources on the web for creating bootable USB devices. Search on “How to create bootable USB drives”.

Creating a Bootable CD

Creating a bootable CD is not as simple as creating bootable floppy disks. Intel is unable to assist with the creation of bootable devices. You can search for resources on the web for creating bootable CDs. Search How to create a bootable CD.

Note
  • 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 desktop board.
