To access the BIOS from within Windows 10, open the Start Menu, then Shift-Click “Restart” and navigate to UEFI Firmware Settings. You can also access the BIOS by tapping F2, F8, Delete, or another key when the POST or manufacturer splash screen is visible during startup. The BIOS, or UEFI, is a powerful tool for configuring your PC’s hardware such as your RAM, CPU, motherboard, and more. It also has options that can increase the security of your PC. Here are a few different ways to access the BIOS. What Is the BIOS? The Basic Input-Output System (BIOS) is low-level software that is programmed onto your computer’s motherboard. When you turn on your computer, the BIOS initializes and tests all of the hardware in your PC to ensure it is functioning correctly. By accessing the BIOS, you can customize how your PC’s hardware functions. Warning: Be careful though — some of the options available in the BIOS can physically damage your computer. If you’re going to try overclocking components, be sure you understand Accessing the BIOS/UEFI at Startup When you start your PC, there will usually be a splash screen that displays the manufacturer’s ...

How much do you know about the inner workings of your computer system? Though it's wise to leave tech-related maintenance and troubleshooting to the professionals in most cases, it's good to familiarize yourself with the fundamentals. When we gain a better understanding of system components and operations, we can better identify issues and either resolve them ourselves or explain the problem to a service person clearly. So today, we're looking at BIOS. This article gives you the whole lowdown on BIOS, including exploring what a computer BIOS is, what a BIOS update is, the function, type, and availability of BIOS, and the different versions and manufacturers. Let’s begin by answering the question, “What is a BIOS in a computer?” What is BIOS? BIOS, pronounced "BYE-oss," stands for Basic Input Output System and is software stored on a small memory chip in your system's motherboard. When you boot up your system and look at the screen at the right time, you may see a startup message that uses the term "BIOS." You may have possibly heard variations of the term "BIOS." But, for example, if you're wondering, "Then what is a BIOS?" no worries. It's the same thing. BIOS is alternately called ROM BIOS, PC BIOS, and System BIOS. BIOS is the first software that runs when you power on your system, performing an initial pack of diagnostic tests (POST, or Power On Self-Test) to see if there are any issues with the hardware. POST is the first step in your hardware’s boot sequence. The mac...

" " BIOS uses Flash memory, a type of ROM. The BIOS software has a number of different roles, but its most important role is to load the operating system. When you turn on your computer and the microprocessor tries to execute its first instruction, it has to get that instruction from somewhere. It cannot get it from the operating system because the operating system is located on a hard disk, and the microprocessor cannot get to it without some instructions that tell it how. The BIOS provides those instructions. Some of the other common tasks that the BIOS performs include: • A power-on self-test (POST) for all of the different hardware components in the system to make sure everything is working properly • Activating other BIOS chips on different cards installed in the computer - For example, • Providing a set of low-level routines that the operating system uses to interface to different hardware devices - It is these routines that give the BIOS its name. They manage things like the • Managing a collection of settings for the The BIOS is special software that interfaces the major hardware components of your computer with the • Check the CMOS Setup for custom settings • Load the interrupt handlers and device drivers • Initialize registers and power management • Perform the power-on self-test (POST) • Display system settings • Determine which devices are bootable • Initiate the bootstrap sequence The first thing the BIOS does is check the information stored in a tiny (64 comp...

• You may need to enter BIOS to install new hardware or enable or disable features built in to your computer. • To do this, restart your computer and look for the "setup" or "BIOS" message telling you which key to press. • Common keys include Esc, Tab, Del, or one of the function keys, often F2 or F10. How to Enter BIOS The steps below can be used to access the BIOS setup utility on your PC, no matter what operating system is installed. This is because the BIOS is part of your • Watch for an "entering setup" message in the first few seconds after turning on your computer. This message varies greatly from computer to computer and also includes the key or keys you need to press to enter BIOS. Here are some common ways you might see this BIOS access message: • Press [key] to enter setup • Setup: [key] • Enter BIOS by pressing [key] • Press [key] to enter BIOS setup • Press [key] to access BIOS • Press [key] to access system configuration You may need to press the BIOS access key several times to enter BIOS. Don't hold the key down or press it too many times or your system may error or lock up. If that happens, just restart and try again. If you don't catch the key sequence needed to get into BIOS, reference one of these lists or check out the tips below: • • •

The BIOS is still the first thing that runs on the just-started CPU and responsible for getting the motherboard hardware turned on, setting basic chipset modes and registers, initializing some hardware, and running the code that loads the kernel. The BIOS is usually not used once the kernel is loaded, and depends on a 16-bit execution environment as opposed to the 32- or 64-bit protected mode environment that a modern kernel operates in. The boot loader normally does require the BIOS IO calls to get the kernel into memory. The BIOS is being replaced even in this role by newer boot-time software such as The discovered hardware configuration, memory range settings, and ACPI metadata tables are probably the only BIOS-based data used by the OS after the kernel is loaded. Any runnable ACPI code is encoded as ACPI Machine Language and is interpreted by the OS. Any good traditional book on MS-DOS assembly programming will include information on the BIOS programming interface. Check out I wrote BIOS for notebook computers for several years. The BIOS does a lot of things while the OS is running. A major task is to inform the OS when many events happen so the OS can look smart (as if it somehow figured these things out on its own). For example, the BIOS tells the OS when: the power button is pressed, batteries are inserted or removed, AC power comes or goes, the system connects to or disconnects from a docking station, hard drives and or certain types of optical drives are inserted ...

You don't need to update your computer's BIOS or UEFI unless there is a specific feature or bugfix your system requires. An error while updating your BIOS can brick your PC, rendering it completely inoperable. Updating your computer’s operating system and software is important. On the other hand, we have previously covered why you shouldn’t generally BIOS updates will not make your computer faster, they generally won’t add new features you need, and they may even cause additional problems. You should only update your BIOS if the new version contains an improvement you need. Why You Probably Shouldn’t Update Your BIOS BIOS updates aren’t big software upgrades that add new features, security patches, or performance improvements. BIOS updates typically have very short change logs—they may fix a bug with an obscure piece of hardware or add support for a new model of CPU. If your computer is working properly, you probably shouldn’t update your BIOS. You likely won’t see the difference between the new BIOS version and the old one. In some cases, you may even experience new bugs with a new version of the...

A quick check of a couple of B550 boards on the Eclypsium list, however, highlights that they're still missing the new BIOS update, though I have seen the new firmware available for Intel boards. After the Asus debacle I am waiting for a response to confirm that the use of a beta BIOS won't affect your motherboard warranty. 1. Signature Verification: GIGABYTE has bolstered the validation process for files downloaded from remote servers. This enhanced verification ensures the integrity and legitimacy of the contents, thwarting any attempts by attackers to insert malicious code. 2. Privilege Access Limitations: GIGABYTE has enabled standard cryptographic verification of remote server certificates. This guarantees that files are exclusively downloaded from servers with valid and trusted certificates, ensuring an added layer of protection. Original story, June 1, 2023: It's not a great time to be a motherboard manufacturer. First, The vulnerability has been discovered by security company, "We are working with Gigabyte to address this insecure implementation of their app center capability," reads its report. "In the interest of protecting organizations from malicious actors, we are also publicly disclosing this information and defensive strategies on a more accelerated timeline than a typical vulnerability disclosure." Eclypsium has published It also doesn't matter if you're running an AMD or Intel system; the vulnerability affects both platforms. All it would theoretically tak...
