Practically any computer user has ever had to work with and Bios, or even to hear the name.In other words, it can be called the basic input and output system, which is run at system startup.To do this, use the delete key by default (but in some cases, instead using key group F).Those who've debug the system in this manner, they know the purpose of Bios.But for novice PC users should be made clear: "BIOS" firmware is recorded and stored in a special chip inside the system - namely, the motherboard or video card.
Purpose
For what need bios?In fact, its role in the system is very high.It Bios sets all the basic settings required for the operation of our computers, defines the necessary function adjusts fan speeds, etc.Without it, the system will not start: simply can not understand how to do it.Also, in most cases, when the machine needs repair, the master has to make certain steps in this mode.
Initially, the question of how to update the Bios, actually arises from the users.And not because then the motherboard or graphics card things were so good.Just bios at the time was built originally recorded once and for all on-chip, and not subject to rewriting.Instead of flashing (it - update) had to buy a new part.But over time, there was an inexpensive and convenient flash memory, and began to write bios on it.This gave the opportunity to the owners of computers to do their own re-flash.
How to update the Bios-video and when to do it
Numerous guidelines for conducting this procedure, great attention is paid to the description of the reasons.Moreover, until recently, it was believed that it is better not to take up the update without urgent need.The explanation is simple: the flashing requires certain knowledge and skills, which can boast not every user.In fairness it should be noted that the problem is not so complicated, and handle it with due attention can be.
So, we list the reasons why people are starting to wonder how to update the Bios.
various minor bugs and conflicts in the configuration of the computer.If serious problems in the video cards are usually solved in the testing process, the less important can sometimes successfully "pass" all testers.As a result, users have to deal with the pesky problem yourself.An example of such an error is the inability to boot the system after the installation of a video driver.
lovers new products and improve the ability to update the BIOS only because it came a new version.Such action in some cases not meaningless.The fact that the new firmware (by the way, to them and the program-flasher need the appropriate version) improve overall graphics performance.For security reasons it is important to take these programs only from trusted sites, the best - from the official.
Another reason may be to add support for addressing side bus, or bypassing the main (system) bus.As in the previous version, it improves performance, but can lead to instability of the computer.
Other Bios update to change the settings.For example, to sign the original card has no name.Most often it comes down to the usual childishness, but, oddly enough, is a very popular cause.In addition, the flashing may be required for better overclocking, which is practiced by some owners of PCs, and to add support for Bios-th Russian fonts.

The next step is to create a bootable floppy disk.To do this properly, we need to copy the firmware and flasher to the root of the carrier.Create a floppy disk, reboot and load the computer is made with the carrier.Command prompt appears, where you have to enter the command «nvflash new.rom» (without the quotes), replacing nvflash proshivalschika program name and the name of the old BIOS new.rom-.
appearance of error and stops operation at this stage means that you need to use a different version proshivalschika.If all goes well, then you will be prompted for permission action.We agree.The image on the monitor turns off for a few seconds, during which established a new version of the BIOS.After this will only be rebooted for the changes to take effect.
