For some reason, many users believe thatThe primary BIOS input / output system, as a program, needs to be upgraded. This is not quite true. About whether you need to update the BIOS, then we'll talk. But once it is worth noting that if the computer is working without failures, it is strictly recommended not to engage in such things, since it is connected with rather serious risks.
First of all, each user should clearly understand that the firmware of the primary system is integrated into a special chip on the motherboard, and not located on the hard disk.
In addition, the upgrade of this system does not providecomputer performance device. In some cases, manufacturers indicate that a new firmware can simply improve the stability of the system. But this is mainly due only to the support of new devices. So, why update the BIOS if the computer is not supposed to install new hardware?
Another thing when a user wants to updatecomputer hardware, say, to install a new processor or memory slots of the latest standard. In this case, of course, an upgrade may be required. But the very process of updating the firmware, even if a special original program is used to update the BIOS from the developer, is not as simple as it might seem at first glance. The slightest discrepancy, a malfunction in the system operation, a power surge - all this can trigger an interruption of the upgrade, which will lead to a complete failure of the entire computer configuration. This will be discussed separately.
As for the types of primary input / output systems - today they are distinguished by at least three:
The first two types are similar to each other quite strongly both in settings and in the appearance of the interface.
The third type appeared relatively recently and is presented in the form of a graphical interface with the ability to control the mouse. Some even compare UEFI with a mini OS (in part, so it is).
In the question whether it is necessary to update the BIOS, one should also take into account possible problems:
But for the UEFI version of the program to updateBIOS can be run directly in the operating system environment. As a rule, the upgrade is performed automatically after the restart of the computer device.
If we talk about the mandatory conditions for an update, you first need to know the version of the primary system.
You can determine it by the chip designation on themotherboard, use the system information called by the msinfo32 command in the "Run" console, or use specific utilities such as AIDA64 Express.
Next you need to download the new firmware version from the sitedeveloper and create a bootable media. After entering the BIOS settings, you should use the Tools menu, which selects the utility for the upgrade, after which the necessary media is installed directly in the update section and an update file is used.
If a USB drive is used, it is desirable to connect it to a stationary PC for the port that is located directly on the motherboard (on the back of the system unit, not in front).
Particular attention should be paid topower supply. During the upgrade, you must exclude any possibility of voltage drop or computer shutdown. To do this, you need to install an uninterruptible power supply with a stabilizer.
And, of course, you need to download the firmwareexclusively from the official resources of developers and motherboard manufacturers, in strict accordance with the version numbers. In some cases, the download may require disabling the antivirus, and when starting from the USB-media - disable the additional ports.
Thus, in the question of whether to updateBIOS, the answer arises by itself: if the computer is not supposed to install new hardware that is not supported by the old firmware, it is better not to do it. Anyway, no performance effect will be achieved. But if the decision on the upgrade is still made, you need to be extremely careful and observe all the mandatory conditions, otherwise the lamentable consequences can not be avoided.
