How to UPDATE BIOS

Upgrading your computer’s BIOS can make your system boot faster, fix some compatibility issues, and improve performance.

A tiny BIOS chip hidden deep inside each computer, it not only supports the computer but also helps protect. BIOS stands for basic input and output system and the BIOS is the first software that the computer will load on boot, before all other devices in the computer such as CPU, GPU and motherboard chipset. But a few years ago, motherboard manufacturers working with Microsoft and Intel introduced an alternative to traditional BIOS chips called UEFI (Unified Extensible Firmware Interface).

Most of the current motherboard chip feature UEFI BIOS chip not, but both have the same goal in mind: to prepare the system to boot into the operating system. That said, most people still call UEFI “BIOS” because of the familiarity of terminology.

Why you should (or should not) upgrade the BIOS

Understanding UEFI is very important to be able to understand how to take advantage of the feature updates and fixes that come with the BIOS updates provided by the motherboard manufacturers.

The motherboard can use any firmware revision that the motherboard manufacturer has built. During the use of the motherboard, manufacturers will release new firmware or BIOS updates, enable new processor and memory support, or resolve common errors. For years, the only real reason to update for the new firmware version was to address some of the bugs in UEFI or replace a newer CPU for the motherboard.

However, Duo’s report indicated that the UEFI firmware attack was a malicious attack. The antivirus software may not detect. Some people want to regularly check and update the UEFI firmware package. However, this may damage the motherboard. It is best not to update the UEFI firmware unless the firmware updates the content you need. However, it is possible to update BIOS updates if you have a new chipset or motherboard.

How to UPDATE BIOS

When booting up the computer, you will see the message informing you that the button is pressed to enter the UEFI BIOS. Hit it! (Need the exact button because the UEFI motherboard design of all motherboards is different).

Although not all motherboards offer this feature, for certain types, you can boot into the UEFI console and use an integrated update utility to connect to it. Internet and latest firmware from the manufacturer’s server.

If your computer does not have this direct support utility, please follow the steps below.

Step 1: Determine your current BIOS version

The easiest way to find the BIOS version is to open the System Information app in Windows – just type msinfo32 into the search bar (Windows 7/Vista) or the Run box (XP) and click System Summary; Your BIOS version will now be displayed on the right, below the processor speed display. Record your version number (and the date that appears after that version number if applicable).

Step 2: Check the motherboard manufacturer’s website

Most computer manufacturers are upgrading BIOSes based on a particular line or model, so visit the support page of your BIOS manufacturer and check its listing. If you download and install a BIOS for another model, your computer probably will not work (although most BIOS upgrades are smart enough to let you know that you are. install it on the wrong hardware). If there is an update file for your BIOS in the list, download the upgrade file, along with any accompanying documentation, as specific warnings and instructions will be included in the documentation. Read Me.

In the process of finding BIOS updates from the motherboard manufacturer’s website. If you can not remember the model number of the manufacturer, then you can look it up without opening the case by downloading and running CPU-Z, then click on the Mainboard tab.

Step 3: Read the accompanying documentation

The BIOS upgrade file may include a list of patches and new features, often to support new hardware. For example, when we performed the BIOS update for our Lenovo Thinkpad T500, the upgrade software provided support for the new AC adapter and 1600×900-pixel screen resolution on the external monitor; This update also fixes issues with fan speeds and webcams, which are problems that can not be fixed by upgrading Windows.

More importantly, the notes in the Read Me file: If you are using Vista on a T500 as our test, you need to make sure that you have installed a patch; And if the T500 has a different graphics card then you will need to upgrade the driver for it on this version before upgrading the BIOS. Read the documentation carefully. You will probably get your computer unable to boot without knowing why.

Step 4: Upgrade the BIOS

Most new computers have a BIOS upgrade procedure. Just download the .exe file from the manufacturer’s website, exit all programs, run the .exe, and do it yourself. work for you; then restart. If your computer suddenly shuts down during the BIOS upgrade, you will not be able to boot, so make sure you do not run out of battery power.

However, older computers may require that you set up a boot disk to upgrade the BIOS. You can download an application for configuring USB, a blank CD / DVD, even a floppy diskette to do this, or an ISO image file used in the burn application (if you do not already have one). Let’s try ISO Recorder for Windows XP and Windows 7 / Vista) to create a BIOS update CD.

Other systems will force you to copy some files to the boot disk, restart and open the BIOS during startup (usually pressing a certain key for the installation options) and changing the boot order for the system to find. The device boots before loading the operating system from the hard drive.

Again, updating the BIOS on a computer can have many benefits, but it is important to understand the risks. Do not touch it if there is no clear, convincing reason to update the UEFI firmware.
