Your computer’s Basic Input/Output System (BIOS) is a crucial component that controls the initialization and hardware settings of your computer. Identifying the BIOS version can be helpful when troubleshooting issues or determining compatibility with certain software or hardware upgrades. In this guide, we will walk you through various methods to identify the BIOS on your computer, whether you are using a Windows, macOS, or Linux operating system.
Understanding The Basic Function Of A Computer’s BIOS
The Basic Input/Output System (BIOS) is a vital component of every computer. It is a firmware that initializes hardware and software during the booting process, enabling the operating system to load. Understanding the basic function of a computer’s BIOS is essential for troubleshooting issues, updating firmware, and optimizing system performance.
The BIOS performs several critical functions. Firstly, it identifies and tests hardware components like the CPU, memory, and drives to ensure they are functioning correctly. It also conducts a Power-On Self-Test (POST) to detect any hardware faults before the operating system takes over. Additionally, the BIOS configures various settings, such as boot priority and date/time, providing a user interface to modify them.
Moreover, the BIOS acts as an intermediary between the hardware and the operating system. It translates instructions from the operating system into commands that the hardware can understand. Without a functioning BIOS, a computer cannot boot or operate.
By familiarizing yourself with the basic functions of a computer’s BIOS, you can troubleshoot hardware issues, customize system settings, and maximize the performance of your computer.
Different Types Of BIOS: Legacy BIOS Vs. UEFI BIOS
Legacy BIOS and UEFI BIOS are two different types of firmware that are used to initialize the hardware components of a computer during the boot process.
Legacy BIOS, also known as the Basic Input/Output System, has been the standard firmware for PC systems for several decades. It uses a more traditional approach and is compatible with older operating systems and hardware devices. However, it has certain limitations, such as the 2.2TB hard drive size limit and slower boot times.
On the other hand, UEFI (Unified Extensible Firmware Interface) BIOS is a newer firmware that offers several advantages over legacy BIOS. It supports larger hard drive sizes, faster boot times, and more secure boot process with features like Secure Boot. UEFI BIOS also provides a graphical user interface, making it easier to navigate and configure various settings.
To identify whether your computer has a legacy BIOS or UEFI BIOS, you can check the BIOS mode in the system information on Windows or use the System Information utility on Mac. Understanding the type of BIOS your computer has is crucial as it determines hardware compatibility, system performance, and the available features.
Identifying Your Computer’s BIOS Version On Windows Systems
Windows systems offer several ways to identify the BIOS version on your computer. The easiest method is to use the System Information tool. To access it, press the Windows key + R, type “msinfo32” in the Run dialog box, and hit Enter. In the System Information window that appears, scroll down to the “BIOS Version/Date” field. Here, you will find the BIOS version installed on your computer.
Another way to identify the BIOS version is through the Command Prompt. Press the Windows key + R, type “cmd,” and click Enter to open the Command Prompt. In the Command Prompt window, type “wmic bios get smbiosbiosversion” (without the quotes) and press Enter. This command will display the BIOS version.
If you prefer a graphic interface, you can also use third-party software like CPU-Z or Speccy, which provide detailed information about your system, including the BIOS version.
Knowing your computer’s BIOS version is essential for troubleshooting, hardware upgrades, and compatibility with certain software. Keep in mind that newer BIOS versions often include bug fixes, enhanced performance, and security features. So, staying updated is generally recommended for optimal computer functioning.

Identifying Your Computer’s BIOS Version on Mac Systems
In order to identify your computer’s BIOS version on a Mac system, follow these simple steps:
1. Turn on your Mac and wait until the Apple logo appears on your screen.
2. Immediately press and hold the “Option” key on your keyboard.
3. Keep holding the “Option” key until you see a list of bootable devices on your screen.
4. Among the listed options, you should see an icon labeled “EFI Boot” or “EFI Boot Volume.”
5. Click on the “EFI Boot” icon using your trackpad or mouse, and your Mac will boot into the EFI firmware settings.
6. Once you are in the EFI firmware settings, you will see the BIOS version information displayed on the screen.
7. Take note of the BIOS version number for future reference or to troubleshoot any compatibility issues.
Please note that the steps to access the BIOS menu may vary slightly depending on the model and year of your Mac. If you are unable to locate the BIOS version using this method, refer to the Apple Support website or consult the user manual specific to your Mac model.
How to Access the BIOS Menu on Different Computers
Accessing the BIOS menu is essential for various purposes such as changing hardware settings, troubleshooting system issues, or updating the BIOS version. However, the method to access the BIOS menu varies depending on the computer’s manufacturer and model. Here are a few common methods to access the BIOS menu:
For most computers:
1. Start or restart your computer.
2. Look for a message on the initial boot screen that instructs you to press a specific key to enter the BIOS setup. This key could be F2, F10, Del, or Esc. Note that the key might vary, so pay attention to the screen.
For Dell computers:
1. Start or restart your computer.
2. Once the Dell logo appears, press the F2 key multiple times until the BIOS menu opens.
For HP computers:
1. Start or restart your computer.
2. HP computers usually have the key combination Esc, F1, or F10 for accessing the BIOS setup. Press the corresponding key repeatedly until the BIOS menu appears.
Remember that accessing the BIOS menu requires careful timing. If you miss the opportunity, restart your computer and try again.
Checking For BIOS Updates And Their Importance
Keeping your BIOS up to date is essential for maintaining optimal performance and security for your computer. BIOS updates often include bug fixes, improved hardware compatibility, enhanced system stability, and even new features. Here’s a brief guide on how to check for BIOS updates and why they are crucial.
To begin, visit your computer manufacturer’s website and navigate to the support section. Look for a tab or link related to drivers and downloads. Enter your computer’s model number or select it from a list provided. Once you find the BIOS section, download the latest update available for your specific model.
Updating your BIOS is important for several reasons. First, it ensures that your computer is running on the latest firmware, which can provide better overall performance. A BIOS update may also address known issues or vulnerabilities that could compromise your system’s security.
Moreover, updating your BIOS can improve hardware compatibility, allowing your computer to recognize and work seamlessly with new components or peripherals. It can also unlock additional features or options that were not available in the previous BIOS version.
