How to update Bios video cards

Virtually any PC user has ever had to either work with Bios, or at least hear such a name. In other words, it can be called a basic input and output system, which is started when the operating system is loaded. To do this, use the default delete key (but in some cases, the keys of group F are used instead). Those who have been able to debug the system in this mode know the purpose of Bios. But for novice PC users, it should be explained: "BIOS" is a microprogram written and stored on a special chip inside the system unit, namely the motherboard or video card.

Purpose

Why do we need a bios? In fact, his role in the system is very great. It is Bios that sets all the basic settings necessary for the operation of our computers, determines the necessary functions, regulates the rotation speed of coolers, etc. Without it, the system will not start: it simply can not understand how to do it. Also in most cases, when the machine needs repair, the master has to perform certain actions in this mode.

Initially, the question of how to update Bios did not actually arise for users. And not because then it was so good with the motherboard or video cards. Simply, the BIOS at the time was originally built-in, written once and for all on a chip, and it was not subject to rewriting. Instead of flashing (it's an update), I had to buy a new part. But over time, inexpensive and convenient flash memory appeared, and the BIOS was recorded on it. This gave the owners of computers the opportunity to do a firmware upgrade themselves.

How to update Bios-graphics cards and when to do it

In numerous manuals for conducting this procedure, great attention is paid to the description of the causes. Moreover, until recently, it was thought that it was better not to undertake renewal without the urgent need. The explanation is simple: a flashing requires certain knowledge and skills that not every user can boast of. For the sake of justice it is worth noting that the task is not so difficult, and you can deal with it with due attention.

So, let's list the reasons why people start to wonder how to update Bios.

Various small errors and conflicts in the configuration of the computer. If serious problems in the work of video cards are usually solved during the testing process, the less important ones can safely "pass" all the testers. As a result, users have to deal with annoying problems themselves. An example of such an error is the inability to boot the system after installing any graphics card driver.

Fans of new products and improvements are able to update the BIOS only because its new version was released. Such actions in certain cases are not meaningless. The fact is that the new firmware (by the way, to them and the program-broach need the appropriate version) increase the performance of the video card. For security reasons, it is important to take such programs only from trusted sites, best of all from an official site.

Another reason may be the desire to add support for addressing on the secondary bus or bypassing the main (system) bus. As in the previous version, this improves performance, but can lead to instability of the computer.

Others update Bios to change the parameters. For example, to sign an initially unnamed video card. Most often it comes down to the usual childishness, but, strangely enough, it is a very popular reason. In addition, flashing can be required for more efficient overclocking of the video card, which is practiced by some PC owners, and for adding support for the Bios-om Russian fonts.

How to Update Bios: A Quick Guide

To start, you need to download (preferably from official sources) the latest firmware and firmware versions. Also, the software for any video card includes utilities for copying the BIOS. They can be found on the computer, using the search, or re-downloaded on the manufacturer's website. Using one of these programs, the Bios video adapter is copied. A copy will help roll back the system in case of failure.

The next step is to create a bootable floppy. To do this correctly, you need to copy our firmware and flasher to the root folder of the media. After creating a floppy disk, we perform a reboot and load the computer from the media already made. A command line appears , in which you need to enter the command "nvflash new.rom" (without the quotes), replacing nvflash with the name of the program of the stitcher, and new.rom - the name of the old BIOS.

The appearance of an error and the termination of work at this stage means that you need to use a different version of the flash driver. If everything goes right, you will be asked to decide the action. We agree. The image on the monitor will go off for a few seconds, during which a new version of the BIOS will be installed. After that, you will only have to reboot, for the changes to take effect.

Now you know how to update Bios. To pre-test the compatibility of the new version with the video card, it is recommended to test the downloaded update by VGABios. In addition, it does not hurt to create an emergency diskette. If these problems cause difficulties for the owner, it is better to ask a specialist for assistance.
