|BIOS updates must be obtained from the computer or motherboard manufacturers website. It must be an exact match for your hardware or the update will fail. Such an update should only be done if it was designed to solve a specific problem you are having. A BIOS update is inherently risky as even if you do everything right the update could fail - leaving you with an unbootable system.|
Think twice about whether you need to do this, and then think again.
