How to Flash BIOS in DOS With Vista

How to Flash BIOS in DOS With Vista thumbnail
A computer running Vista may need a BIOS update.

When an update to the BIOS of your computer's motherboard is available from the manufacturer of the computer, it can be updated by flashing the BIOS. In order to do this in Windows Vista, you may need to be in DOS mode. This can be done by creating a bootable CD with a Windows image that also contains the BIOS update files. You can do this using Nero or Nero Lite.

Things You'll Need

  • Nero or Nero Lite
  • Windows boot image
  • Blank CD

    • 3

      Insert a blank CD into the drive on your computer.

      Click the "New" button in the toolbar and then select "CD-ROM (Boot)" from the left pane.

      Select the Boot tab and then click the "Browse" button. Locate the image file on your system that you downloaded in Step 2. Do not change any of the options under the Advanced section.

      Click the "Write CD" or "Burn" button on the toolbar and then click the "Burn" button at the bottom of the window to burn the CD.

      Leave the CD in the drive and then restart the computer and wait while it boots from the CD.

    • 12

      Type in the name of the executable file for the BIOS update at the command prompt and wait while your BIOS is being updated. When the update has finished, eject the CD and then restart the computer.

Tips & Warnings

  • Putting the BIOS files on the bootable CD allows you to easily run the update without having to use a separate disc.

  • If the BIOS update fails, you will not be able to use your computer.
