The BIOS resides on your motherboard and controls all basic functions of your computer.
Your basic input/output system, or BIOS, is an important piece of software that resides on a read-only memory, or ROM, chip on your computer's motherboard. The BIOS controls many aspects of how your computer runs and how Vista will interact with much of the hardware in your computer. If your BIOS software falls out of date, without an update your system may suffer serious and frustrating problems. Fortunately a BIOS update in Vista is a simple task.
Instructions
1. Open your Web browser in Vista and do an Internet search for your motherboard manufacturer's website. The name of the manufacturer of your board is included in the documentation that came with your computer.
2. Visit the support area of your board manufacturer's website for downloading files and upgrades. Click to download the latest flash software for your BIOS. Flash simply means that the software is designed to actually erase your BIOS ROM chip by charging it before writing the new software.
3. Double-click on the file you downloaded to launch the executable and begin the update process. Accept the license agreement and click "Next." When the update starts, ensure that your computer stays powered on, as any interruption to the power during the update will likely render your computer inoperable.
