What is the BIOS?
The BIOS is firmware built into the computer's motherboard, acting as the bridge between the hardware and software. Accessing the BIOS allows you to configure crucial settings, such as boot order, overclocking, security options, and much more. This article will explore the process of accessing the computer BIOS system and provide a step-by-step guide for Windows and macOS.
The BIOS initializes the hardware components of your computer, performs a Power-On Self-Test (POST) to check for errors, and then loads the operating system. It also provides a user interface that helps you modify various hardware and system configuration settings.
Important Tips
When accessing the BIOS or similar firmware interfaces, exercise caution and avoid making changes unless you are familiar with the settings. Incorrect changes can cause system instability or even render your computer inoperable.
If you are uncertain about specific settings within the BIOS, refer to your computer's manual or the manufacturer's website for detailed information.
Accessing the computer BIOS system is a valuable skill that allows you to customize and optimize your computer's settings. Whether you are a Windows or macOS user, understanding how to access and navigate the BIOS gives you greater control over your computer's hardware and configuration. Remember to be cautious when making changes and refer to the manufacturer's documentation for detailed instructions.
Accessing BIOS on PC
a. Restart your computer: Begin by restarting your Windows computer. You can either click on the "Start" menu and select "Restart" or use the keyboard shortcut by pressing the Windows key + X and selecting "Restart" from the power options.
As your computer restarts, pay close attention to the initial boot screen. Look for a message instructing you to press a specific key (usually Del, F2, F10, or Esc) to enter the BIOS setup. This key varies depending on the computer manufacturer. Press the designated key promptly.
Once inside the BIOS setup, you will see a menu-driven interface. Use the arrow keys to navigate the options and Enter to select a menu or make changes. Different BIOS versions have different layouts, so explore the options to find the settings you need to modify. Remember to save any changes before exiting the BIOS.
There are other ways to access BIOS on Windows.
One is by using the advanced startup options in system settings. On Windows 10 and 11, you could search for the term and click on it. Clicking the "Restart now" button will restart your system into BIOS.
A hacky way to restart your Windows system in BIOS is by using a neat CMD command: shutdown /r /fw /f /t 0. Just open your command prompt as an administrator and input the command. Beware that your computer will restart after you press enter, so ensure to save your work before running it.
Accessing "BIOS" on macOS
Mac computers do not have a BIOS, but a similar firmware called EFI (Extensible Firmware Interface).
Start by restarting your Mac computer. You can click on the Apple menu and select "Restart."
Press and hold specific keys: As your Mac restarts, immediately press and hold the Option (Alt) key on your keyboard, which will bring up the Startup Manager, where you can choose different startup disks.
In Startup Manager, you will see a list of available startup disks. Look for an option labeled "EFI Boot" and select this option, and your Mac will boot into a utility that resembles the BIOS, called the Extensible Firmware Interface (EFI). Here you can modify system settings similar to the BIOS.
