How to Check BIOS Version on Windows
Checking your BIOS version on Windows is straightforward, and you have multiple options. Here’s a detailed look at how you can achieve this.
Using System Information Tool
The easiest way to access your BIOS version is through the System Information tool. Follow these steps:
- Press Windows + R to open the Run dialog.
- Type msinfo32 and hit Enter.
- In the System Information window, scroll down to "BIOS Version/Date". Here you will see your BIOS version listed.
Remember to note down the version for troubleshooting or updates.
Using Command Prompt
For those who prefer using command line tools, you can also check your BIOS version using Command Prompt:
- Open Command Prompt by typing cmd in the Windows search bar.
- Type the command: wmic bios get version and press Enter.
This command will display your BIOS version in a clear format.
Check BIOS Version on Startup
Another method is to check your BIOS version at startup. When you power on your computer, look for a splash screen that shows the manufacturer’s logo. Often, your BIOS version will be displayed at the bottom of this screen. You may need to press a specific key (like F2, F10, or Delete) to enter the BIOS setup for more detailed information.
Using Third-Party BIOS Version Checkers
There are also specialized tools designed to check BIOS versions. Software such as CPU-Z or Speccy can provide a graphical interface for accessing your BIOS information, making it easy to find and understand.
Conclusion of Windows Methods
Now that you know how to find your BIOS version on Windows, these methods can help you verify your current BIOS setup. Let’s move on to check BIOS versions on Macs.
Checking BIOS Version on Mac
For Mac users, checking the EFI version (the Mac equivalent of BIOS) requires a different approach. Here’s how to do it.
Using About This Mac
To easily access your Mac's firmware version, use the "About This Mac" feature:
- Click on the Apple icon at the top left of your screen.
- Select About This Mac.
- Click on System Report.
In the System Report, under the "Hardware Overview", you will see the "Boot ROM Version" and "SMC Version", which serves as your BIOS information.
Terminal Command for BIOS Version
Alternatively, you can check your Mac's firmware version using the Terminal:
- Open Terminal from the Applications > Utilities folder.
- Type the command: system_profiler SPHardwareDataType | grep "Boot ROM Version" and press Enter.
This command will output the Boot ROM version, confirming your firmware version in a quick manner.
Boot Up Check on Mac
You can also identify your BIOS version on boot up. Restart your Mac, and hold down the Option (⌥) key while it boots. This will lead you into the boot manager, where you can view firmware details on start-up options.
Conclusion of Mac Methods
With these methods, checking your BIOS version on a Mac is easy and quick. Now, let’s see how to check BIOS version on Linux systems.
Check BIOS Version on Linux
Linux users have several options for checking their BIOS version, leveraging terminal commands and system files.
Using Terminal Commands
To find your BIOS version via the Linux terminal:
- Open the terminal.
- Type the command: sudo dmidecode -s bios-version and press Enter.
This command will display the BIOS version directly in the terminal.
System Information Panel
Another option is to use the system information panel, typically available in your Linux distribution’s settings menu. Navigate to the section displaying system hardware information to view BIOS details.
Accessing BIOS from GRUB Menu
If you want to check the BIOS on boot-up, you can access the GRUB menu during start-up. Hold down the Shift key (or Esc key depending on your distribution) right after powering on your machine and you’ll find information regarding firmware settings here.
Common Tools for Linux BIOS Version Check
There are third-party tools like Hardinfo and Lshw which can also be used for more user-friendly BIOS information retrieval. These applications present BIOS details in a graphical interface, which can be easier for less experienced users.
Conclusion of Linux Methods
Now you are equipped with several ways to check your BIOS version on Linux. Next, let’s learn how to check BIOS version on different manufacturers’ systems.
