Luckily, most motherboard manufacturers provide an automatic utility for flashing your system's BIOS. Check with the manufacturer's website for details on this process. It used to be quite complex to update a BIOS, but in recent years the companies that make motherboards have started making automated utilities available. Follow the vendor's instructions precisely and use their automated BIOS utility or follow their manual update instructions.
For the most part, the utilities that are available allow you to enter your BIOS information (which you can get from your support documentation) into some fields online. The utility does the rest of the work and updates your BIOS.
An updated BIOS should resolve Windows error code 9. If the error code persists, contact your computer's manufacturer for more in-depth information.
