How To Check BIOS Version | A Review of The Quick and Easy Methods

B.Sc. (Hons), M.Sc., MBCS, CITP

The how to check BIOS version article is a supplementary page for the successful American Megatrends BIOS Update article.

I receive many questions from visitors about how to find out what the BIOS or UEFI make and version are on their devices. This is an important step because you simply cannot update your firmware yourself unless you have this critical piece of information.

Often we are unable to note the BIOS or UEFI details when devices are booting. This is because the information flashes up on screen and disappears before you have a chance to register the information. This is a source of frustration.

In addition, some visitors are not keen on downloading and installing third-party tools and utilities to help identify their device's BIOS details. This is understandable considering the proliferation of malware on the Internet these days.

Therefore, this article focuses on the alternative methods of identifying your BIOS version, focusing specifically on the Windows operating system, This is because it is still the most popular O/S in the world by some margin.

Windows Operating System
MSINFO32 Command and System Information

With modern Microsoft Windows operating systems, from at least Windows 7 and above, it is often straightforward to find the make and version of your devices' Firmware and Motherboard.

This method does not require a system reboot, or any prerequisite changes to pause the boot process, or anything equally complicated, and can be done in three easy steps.

1. Load the Run Command Window by selecting Start > Run, or select the Windows Key + R key. Enter "msinfo32" (without quotations) the click OK.

2. Under System Summary, I have highlighted the information we are interested in. The first details are your computer's BIOS Version/Date. In my case, it is the Lenovo 8VCN27WW, which was released on the 22nd September.

SMBIOS, or System Management BIOS, is the method used to enable information such as your BIOS version and Motherboard Product to be understood (by Operating Systems in this instance). My Laptop is running version 3, which enabled 64-bit technology to be interpreted.

The BIOS mode determines whether your devices is running the modern UEFI version of firmware, or the Legacy version, which is the traditional BIOS we all know and love.

3. The next set of information is the three Baseboard entries. This is your device's Motherboard details, which is important when determining which manufacturer's firmware program you should be applying to your device.

As you can see, my Laptop's Motherboard is the Lenovo LNVNB161216, version SDK0J40709 WIN. It is this information I would use to search the Lenovo website for the latest update packages.

If the package is a later version than what I currently have installed on my Laptop, I will consider updating with this latest version.

To keep a record of your System Information, or to review offline at a later date, for example, you can export the information to a text file, which you can then format at your leisure.

To do this, simply click File > Export, then give the file a name and a location to be downloaded to.

If you are a big user of the Command Prompt, you can also display your devices' System Information here by selecting the Windows Key + R Key, then entering "CMD" (without the quotations), and clicking OK. From here  type "systeminfo" (without the quotations) and hit return.

The Registry Is A Last Resort

I was hesitant to include this method as a means of identifying your computer's BIOS because the Registry should be avoided at all costs if you do not know what you are doing.

However, on the other hand, the article would not be complete without covering this option. We are not changing anything. We are simply to search, and so long as stick to the steps below, no damage should occur.

1. Load the Run Command Window by selecting Start > Run, or select the Windows Key + R key. Enter "regedit" (without quotations) the click OK to load the Registry Editor.

2. Using the Registry Hive structure in the left-hand windowpane, drill down to the location below, then check out the SystemBiosVersion Multi String Value in the right-hand windowpane:-

  • HKEY_LOCAL_MACHINE > HARDWARE > Description > System
