How to Install BIOS Updates
Flashing or updating your BIOS can give your computer new features or correct consistent computer problems. While installing BIOS updates is a fairly simple task, installing the incorrect update or installing the update incorrectly will make your motherboard unusable. Many motherboard and computer manufacturers now include Windows-based flash BIOS programs. If your computer includes such a program, open it and follow the on-screen prompts. You should only flash your BIOS if you need to enable newly supported features on your motherboard or if you are experiencing BIOS-related problems with your computer.
Things You'll Need
- Blank floppy disk or USB flash drive
- Floppy drive or available USB port
Verify that you have the correct BIOS update for your specific motherboard by visiting your computer or motherboard manufacturer's website. Read all instructions provided by your manufacturer.
Close all programs. Double-click the file you downloaded. Access the "readme.txt" if available.
Follow the on-screen prompts. Extract the files if the BIOS update is included in a ZIP file. Allow the built-in Windows-based updater to process the BIOS update if available.
Insert a blank floppy disk or USB flash drive. Copy the files to a floppy disk or a USB flash drive. Include boot disk files, if necessary. Restart the computer.
Enter your BIOS by pressing the appropriate key as shown on-screen immediately after restarting your computer.
Navigate to the "Advanced Boot Options," and choose to boot first from floppy drive or USB drive, depending on your configuration if you must use a boot disk. Navigate to the BIOS Tools or to the appropriate menu in the BIOS and begin the flash process otherwise. Follow the on-screen prompts to complete the process. Save and exit.
Allow your computer to boot into DOS if you are using a boot disk. Type the commands as specified by your computer or motherboard manufacturer to begin updating your BIOS.
Follow the on-screen prompts to complete the BIOS update.

- Connect your computer to a UPS (uninterruptable power supply) to prevent failed updates.
- Update your BIOS at your own risk. Your computer may be unusable if you incorrectly update the BIOS.
