Precaution before updating bios
The BIOS plays an important role in the functioning of the computer.When you switch on the computer, it is the function of the BIOS to activate various computer components and ensure they are functioning properly.Here's the usual process: It's good to have a spare copy of all important files from your PC before you start.Though a failed BIOS update doesn't endanger the data on your hard drive directly, you will be able to access your files and continue working with them on another computer if you have a backup on a removable drive.If there's a power cut, or the computer gets turned off while updating, it could mean that it's unable to boot at all. For this reason, it's worth checking whether you really need to update your BIOS.Read the release notes of the latest version (and each version back to the one currently installed) to see whether it will add the features you need or fix a problem you're having.It’s important as there are ususally subtly different versions, and each might have its own individual BIOS.Plus, you should note down the revision number – for example REV 1.03G as it may require a different BIOS file to previous revisions.
