Important Notes:
- 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.
- 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 specific to the Intel® Desktop Board D945PLNM and are for illustration purposes only. You need to select the correct BIOS files for your desktop board.
Instructions for iFlash BIOS Update [printable PDF version]
With the Iflash BIOS update utility you can update the BIOS from a floppy disk, bootable CD-ROM, bootable USB flash drive or other bootable USB media. (Information on how to create a bootable USB device or CD is listed at the end of this document.)
For other BIOS update methods, click here.
Using the iFlash BIOS update is a two-part process:
Part 1: Create the bootable media (floppy, CD or USB device) containing the BIOS update
Part 2: Update the BIOS of the target computer
If Using a Floppy Disk
If Using a Bootable USB Device
If Using a Bootable CD-ROM
If Using a Floppy Disk
You can use this method if the iFlash files are small enough to fit on a floppy disk and the desktop board includes floppy drive support. You will need a blank floppy diskette.
Part 1: Create the bootable media (floppy) containing the BIOS update
1. Download and save the iFlash BIOS Update file to a temporary directory.
2. Insert a blank floppy diskette into the floppy 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:
5. Double-click the RUN.BAT file. Follow the prompts to create the bootable floppy.
Part 2: Update the BIOS of the target computer
1. Boot the target computer with the floppy disk in the floppy drive. The BIOS update process will begin automatically.
2. On the welcome screen, press any key to continue.
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.
4. Once the update is completed, remove the floppy disk from the drive and press Enter to restart the computer.
If Using a Bootable USB Device
You can 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 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.
2. Double-click the *.EXE to extract necessary files.
3. Double-click the SW.EXE file to extract additional files.
4. Copy IFLASH.EXE and the .BIO file to the bootable USB device.
5. Configure the BIOS of the target computer to boot to the USB device:
a. Press F2 during boot to enter BIOS Setup.
b. Go to the Boot menu.
c. Enable USB Boot.
d. 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:
a. Press F2 during boot to enter BIOS Setup.
b. Go to the Boot menu.
c. Enable USB Boot.
d. 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 filename of the .BIO file) to launch the iFlash BIOS update process. Follow all prompts.
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.
2. Double-click the *.EXE to extract necessary files.
3. Double-click the SW.EXE file to extract additional files.
4. Copy the .BIO file and IFLASH.EXE to the bootable CD.
Part 2: Update the BIOS of the target computer
1. Configure the BIOS of the target computer to boot to the CD-ROM drive:
a. Press F2 during boot to enter BIOS Setup.
b. Go to the Boot menu.
c. In Boot Device Priority, set the CD-ROM drive to be the first boot device.
d. 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 filename of the .BIO file) 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.
