How To Update Your PC’s BIOS blog banner image

The BIOS (Basic Input/Output System) is a fundamental piece of firmware embedded in a computer. It’s responsible for booting up the system and managing data flow between the computer’s operating system and attached devices. Over the years, BIOS has evolved from basic firmware to a more complex and integral part of computer functionality, adapting to the increasing sophistication of modern hardware and software.

Keeping one’s BIOS updated is crucial for ensuring that a computer’s hardware is fully compatible with its operating system. These updates can enhance system performance, improve hardware compatibility, fix bugs, and provide security patches. They are essential for maintaining the overall health and efficiency of a computer.

What are BIOS updates?

BIOS updates refine the firmware that controls hardware-software interaction. They are essential for adapting the system to new technological standards and often include advanced features like secure boot in modern UEFI (Unified Extensible Firmware Interface) systems. UEFI has replaced traditional BIOS on most modern systems. It provides a more user-friendly interface and advanced features. Updating UEFI firmware follows a similar process but often includes additional capabilities like secure boot or network functionality. Nowadays, you can effectively interchange the terms “BIOS” and “UEFI.”

Updating BIOS involves inherent risks, such as potential system instability if the update is interrupted or not applied correctly. It’s crucial to follow the update instructions meticulously and ensure that the update process isn’t disrupted, such as by a power outage.

BIOS updates often also include security patches that protect against vulnerabilities at the firmware level. These updates can be crucial for preventing unauthorized access and ensuring the integrity of the system’s security.

How to check your current BIOS version

Access Windows’ system information applet:

  • Press the Windows key + R to open the Run dialog box.
  • Type “msinfo32” and press Enter. This will open the System Information window.
  • In the System Summary section, look for “BIOS Version/Date.” The information displayed here includes the BIOS version, its release date, and the manufacturer.

Within the BIOS/UEFI menu:

  • Restart your computer.
  • As the system starts to boot, repeatedly press the key that opens the BIOS or UEFI firmware settings. Standard keys include F2, Del, Esc, and F10. The process of entering the BIOS setup can differ slightly between manufacturers, so it’s advisable to consult your computer or motherboard manual if you encounter any difficulties.
  • The specific key can vary depending on the manufacturer of your motherboard or computer. On some systems, F10 might bring up a boot menu instead of the BIOS settings, so knowing the correct key for your specific system is important.
  • Navigate using the keyboard arrows once you have successfully entered the BIOS or UEFI settings. Mouse functionality may not be available in this environment.
  • Look for a tab or section named ‘Main’ or ‘System Information.’ The exact name can vary, but this section typically contains details about your system, including the BIOS version. This version information is often found on the landing page of your BIOS/UEFI menu.
  • Note down the BIOS version displayed. This information is crucial for determining if a BIOS update is needed.
  • After noting the BIOS version, you can exit the BIOS setup. To exit, look for an option like ‘Exit Saving Changes’ or ‘Exit Discarding Changes.’ If you haven’t made any changes, use the option to exit without saving to avoid altering any settings unintentionally.
  • Your computer will then reboot normally, and you can resume using it.

Following these steps, you can accurately determine your current BIOS version, which is essential before proceeding with any BIOS update. Knowing your current BIOS version helps ensure that you are applying a necessary and compatible update. It prevents the installation of incorrect updates that could potentially harm your system’s stability and functionality.

Preparing for a BIOS update

  • Backing up data before BIOS update: It’s crucial to back up important data and system settings before a BIOS update. While BIOS updates typically do not affect data on the hard drive, having a backup is a safeguard against any unforeseen complications that might arise during the update process.
  • Identifying motherboard and BIOS model: Determine your motherboard model and BIOS version by checking your system information or consulting your computer’s documentation. This is crucial for downloading the correct BIOS update tailored to your motherboard.
  • Finding the appropriate BIOS update: Visit your motherboard manufacturer’s website for the latest BIOS update. Ensure the update is designed for your motherboard model to avoid compatibility issues.
