What Is BIOS?<\/h2>\n\n\n\n
BIOS (Basic Input\/Output System) first appeared in the 1970s and remained the same until UEFI (Unified Extensible Firmware Interface) emerged in the 2000s. These days, almost all PCs are running UEFI. BIOS (UEFI) is a type of firmware<\/a> that is installed on your computer motherboard\u2019s microprocessor (ROM chip) that assists in hardware-specific processes.<\/p>\n\n\n\n
The BIOS instructs your computer on basic hardware functions such as changing the settings on your CPU, hard drive, memory, and fan speed, as well as changing any hardware input control (USB and Thunderbolt). It\u2019s also used to recognize any attached hardware such as hard drives, graphics cards, RAM sticks, and the processor. Furthermore, the BIOS detects, and allows you to rearrange, your hard drive\u2019s boot order, which is essential for loading Windows (Bootstrap Loader).<\/p>\n\n\n\n
The BIOS is also important for POST (Power-on Self-Test), which is the initial hardware diagnostic test that makes sure your computer\u2019s hardware is functioning correctly when you turn it on.<\/p>\n\n\n\n
It\u2019s important to note that the BIOS is tied to your motherboard and does not rely on the Windows OS. However, if you are having issues with Windows, it may be caused by a specific setting in the BIOS.<\/p>\n\n\n\n
Types of BIOS<\/h2>\n\n\n\n
There are two primary types of BIOS: BIOS (referred to as Legacy) and UEFI (Unified Extensible Firmware Interface).<\/p>\n\n\n\n
What\u2019s in a Name?<\/h4>\n\n\n\n
Before we begin, there\u2019s one thing to note: at its core, UEFI is just a new standard of the BIOS with cosmetic changes and additional features. So, while it\u2019s technically <\/em>UEFI, even seasoned vets will still call it BIOS.<\/p>\n\n\n\n
Legacy<\/h3>\n\n\n\n
As the name implies, Legacy is the original BIOS and has limited functionality nowadays. For example, it is text based and can only be controlled by a keyboard. It won\u2019t recognize hard drives that are more than 2TB. Also, it does not recognize GUID Partition Table (GPT) disks and Secure Boot, which are minimum requirements for Windows 11<\/a>. Most importantly, you cannot install 64-bit versions of software.<\/p>\n\n\n\n

UEFI<\/h3>\n\n\n\n
Most, if not all, modern computers use UEFI, which is a sleeker, more powerful version of BIOS. You have keyboard and mouse control, can access hardware settings you couldn\u2019t in the Legacy version, and, most importantly, can adjust security options so your computer is completely safe. Here are just a few of the functions of UEFI that weren\u2019t possible with the original BIOS.<\/p>\n\n\n\n
- 32- and 64-bit compatible<\/li>
- Compatible with storage devices more than 2TB<\/li>
- Options to enable GPT and Secure Boot, which are minimum requirements for Windows 11<\/a><\/li>
- RAM, CPU, voltage, fan, and other hardware control<\/li><\/ul>\n\n\n\n

<\/figure>\n\n\n\nWhy Should I Update My BIOS?<\/h2>\n\n\n\n
There are differing opinions on whether you should update the BIOS (UEFI). The answer is \u201cyes and no.\u201d There can be a tremendous upside when updating your BIOS (UEFI). However, it can come with risks. Here are a few reasons why updating your BIOS is good.<\/p>\n\n\n\n
New Motherboard<\/h4>\n\n\n\n
If you\u2019re building a new PC, the motherboard you purchased may have been on the shelf for a bit. From when it was on the shelf to when you\u2019re building your computer, the manufacturer may have released a new BIOS version.<\/p>\n\n\n\n
Hardware Performance<\/h4>\n\n\n\n
If you have an older processor or graphics card but a newer motherboard, you may be missing out on major performance upgrades. For example, an older BIOS version may only allow your computer CPU to access some memory from your graphics card. However, a BIOS (UEFI) update can let the CPU access ALL memory, meaning you\u2019ll see a noticeable difference in graphics performance!<\/p>\n\n\n\n
Hardware Compatibility<\/h4>\n\n\n\n
Some BIOS (UEFI) updates can unlock new features that may make older processors fully compatible. For example, suppose you have an AMD Ryzen A4 processor back from 2017, and you perform a BIOS update. In that case, you can upgrade to the latest, more powerful version without replacing any parts.<\/p>\n\n\n\n
Stability Improvements and Bug Fixes<\/h4>\n\n\n\n
Additional reasons for updating your BIOS are stability and bug fixes. If there are comprehensive reports of a specific issue related to the motherboard, the motherboard manufacturer will release an update (patch) to solve said problem.<\/p>\n\n\n\n
Address Potential Security Threats<\/h4>\n\n\n\n
The most important reason to update your BIOS (UEFI) is to address potential security threats. Hackers can find motherboard vulnerabilities, enabling them to access and steal data, passwords, and encryption keys from others who share the same computer.<\/p>\n\n\n\n
What BIOS Version Do I Have?<\/h2>\n\n\n\n
Before we talk about updating your BIOS (UEFI), you must know how to check what BIOS version you have. If your version matches the latest version on the manufacturer\u2019s website, there\u2019s no need to update.<\/p>\n\n\n\n
While you can always open your BIOS to check, the easiest way is through the System Information<\/em> window.<\/p>\n\n\n\n
- Click the Windows <\/strong>icon, then search for and select System Information<\/strong>.<\/li>
- Look for the BIOS version.<\/li><\/ol>\n\n\n\n

How to Open BIOS<\/h2>\n\n\n\n
There are a few ways you can open your BIOS (UEFI). You can open the BIOS by restarting in Windows or by the classic method of repeatedly pressing a specific key on your keyboard when your computer boots up.<\/p>\n\n\n\n
Open BIOS in Windows<\/h3>\n\n\n\n
If you\u2019re already signed into Windows and want to go straight to the BIOS (UEFI), follow this procedure.<\/p>\n\n\n\n
- Click the Windows <\/strong>icon, then type and select Advanced startup<\/strong>.<\/li>
- Click Restart Now<\/strong>.<\/li>
- Click Troubleshooting<\/strong>, select Advanced options<\/strong>, and click UEFI Firmware Settings<\/strong>.<\/li><\/ol>\n\n\n\n
Open BIOS with BIOS Keystroke<\/h3>\n\n\n\n
IMPORTANT<\/strong>: There\u2019s a limited time from when you turn on your computer to when Windows loads. To ensure you get into the BIOS without needing to restart, follow the tried-and-true method by repeatedly pressing the specific key as soon as you turn on the computer. This ensures you get into the BIOS.<\/p>\n\n\n\n
Depending on your computer\/motherboard brand, you must press a different BIOS key to open the BIOS. Here is the comprehensive list of BIOS keystrokes by manufacturer.<\/p>\n\n\n\n

How to Update BIOS<\/h2>\n\n\n\n
Now that you know the ins and outs of the BIOS and how it works, it\u2019s time to learn how to update it. If you feel uncomfortable updating the BIOS, take it to a computer shop or a qualified PC tech. Follow the motherboard manufacturer\u2019s update procedure carefully, and take your time! Make sure also to have a copy of the motherboard\u2019s user manual.<\/p>\n\n\n\n
IMPORTANT!<\/h3>\n\n\n\n
Before we begin, it is critical to know that if a BIOS update is done incorrectly or if there\u2019s a power failure during the BIOS update, you may brick your computer, and it will no longer function or work correctly! The BIOS update process may take a little time, but do not step away from the computer.<\/p>\n\n\n\n
