How to install BIOS on a computer without a system. Section Main - Main Menu
BIOS - comprehensive program, connecting and also powering the computer components with the operating system. And the rest of the work depends on the quality of its functioning. computer equipment. Therefore, even if other components are working properly, but the BIOS is not, the PC will not work correctly or will not boot at all. Reinstalling or updating the entire BIOS system will help save the situation; you just need to take certain actions.
The first thing you need is to find out what version of BIOS you had originally, as well as what model of motherboard you are using. There are several ways to do this. One of them is through the SETUP menu. After entering it by pressing the Del button in the first minutes of booting the computer, look for the BIOS Version line. The combination of letters and numbers in this line will be the information you are looking for. The second way is to extract data from the information that runs on the screen before loading. To have time to remember the necessary elements, use the PauseBreak button. The third method is the most convenient. With the Start menu open, call command line by clicking “Run” and enter the command “msinfo32” there. In the window that opens, you can easily find everything you need. The next step is preparing the software. If you do not have a backup copy of your BIOS, or you want to reinstall a more recent version, then go to the official website of the company that owns your motherboard model and download from there boot files BIOS. They are usually delivered archived.
Flashing the BIOS input/output system on your own, especially for the first time, is advisable only in extreme cases when there are no other outputs. Otherwise, it is better to entrust it to a specialist. But if you have already taken on this yourself, then remember - throughout the entire reinstallation process, your computer must be reliably supplied with power. With the slightest power surge, failure or interruption, the motherboard will inevitably be damaged and fail.

Bios firmware | reflash reinstall BIOS
Today on the Internet there are many myths and legends that shroud the process firmware - flashing the BIOS on a computer.
I already wrote more about this topic here - BIOS updateMany users still wonder and are perplexed, so why update (reflash) BIOS ?
In short, for example, new processors are constantly being released that are no longer supported by old motherboards, and if not reflash bios, then the network card will not “see” this processor.
In addition, with each new version of BIOS firmware, errors are eliminated, support for new devices is added, and operation between devices on the computer is optimized.
Asus bios update instructions
So let's consider step by step process updates System BIOS ASUS boards. An excellent video tutorial, which is located below on the page, will help us with this.
Where to start first before you want to upgrade and reflash outdated version BIOS? The first step is to visit the website of the manufacturer of your motherboard.
In principle, the name of the motherboard is not decisive, since BIOS flashing process for all well-known motherboard manufacturers it is almost identical.
However, the names are only slightly different utilities for BIOS firmware, but the process itself remains very similar and unchanged.
How to update BIOS asus
In the video tutorial you will see how go to ASUS BIOS... how to find there the utility that we downloaded for new BIOS firmware, how to enter this special update utility.
Many people ask the question: how to update bios on laptop? yes, exactly the same as on desktop computer. No difference. Just on different models For laptops, the procedure for logging into bios is slightly different.
By the way, on the site, in the computer tutorials section, it has already been described in detail how to enter the BIOS and how not to get lost in the sections of this information input and output devices.
Download bios firmware
Where is better download bios updates? Everything is very simple.
If you have an ASUS motherboard, then go to the website of the manufacturer, Asus - their Russian-language resource in Russia www.ru.asus.com
If the motherboard is from GIGABYTE TECHNOLOGY (Gigabyte), then download the BIOS update from the official website www.gigabyte.ru
Accordingly, if you need an update for bios Toshiba(Toshiba) - go straight to www.toshiba.com.ru, and for those with ASER - go to the download center www.acer.ru/ac/ru/RU
But on the website www.bios.ru - not a word about bios :))) there is a completely different topic there. Apparently, the owner of the domain does not want to deal with computer hardware :-)
How to find the required (latest) version of the BIOS update is shown in the video tutorial. Just don’t forget that it’s better to download the BIOS firmware directly from the browser itself (Opera, Mozilla, IE, that is, whatever you’re used to using).
No need sway bios firmware some kind of download manager, like Download Master or ReGet Deluxe. They are of course good to download large files, in order to download files or archives in multiple streams.
But the BIOS firmware file weighs about 2MB, so these threads can only damage it. We will flash the downloaded file into the BIOS memory chip.
Asus bios update
There are often heated debates about updating the BIOS. More precisely, these disputes are mainly due to the methods and methods of flashing the BIOS.
Should I use it? special utilities for flashing the BIOS? Is it possible to update the BIOS directly from operating system Windows?
It is not advisable to update the BIOS from a Windows environment! The Vinods operating system may freeze or glitch in this very inopportune moment, reboot and the BIOS will be flashed with an error!
The motherboard may fail and will have to be repaired or thrown away. But for many motherboards this is the same thing:-(((
By the way, ASUS motherboards, immediately before flashing the BIOS, check this file for integrity, is it damaged? This is a very useful function, and not all motherboards have it (use it before updating) BIOS versions.
In general, use only the BIOS flashing method shown in the video tutorial to avoid an unsuccessful and tragic errors when updating bios.
The BIOS flashing procedure itself takes no more than two minutes.
BIOS recovery
The operation of flashing the BIOS itself is quite risky, because if the BIOS is stitched into the chip incorrectly, then very disastrous consequences are possible.
That is, the motherboard fails and needs to be repaired. True, some motherboards provide a “rollback” to the previous working state, but unfortunately the number of such motherboards is small.
But ASUS motherboards have such technology - how can you restore the BIOS functionality. That is, you can “roll back” or restore the previous version of the BIOS firmware.
The ASUS P7P55D Pro motherboard has such a recovery function. How to use it even before flashing the BIOS will be shown at the end of the video tutorial. So that you do not forget and take advantage of this opportunity during the BIOS update process.
But if your board doesn't even support this function, then don't worry too much. If you do everything as shown in the video tutorial, the update process will go without problems, like clockwork.
I hope that you have already entered the BIOS before and have an idea about it appearance and settings.
There is not only a description of BIOS versions from well-known manufacturers Phoenix, Award, as well as detailed descriptions and screenshots.
Bios flashing lesson
So, even if the firmware file is copied with errors, then before the last stage of updating the BIOS, the ASUS P7P55D motherboard will check this file again and will not allow it to spoil its working BIOS :))))

BIOS program
After watching a video tutorial about flashing the BIOS, you will probably have no doubts about the complexity of this procedure and the myths that surround the supposed complexity of bios firmware
Some people say that there is no need to update the BIOS...
If a new version of the BIOS firmware has been released (and this can be found on the manufacturer’s website), then it is advisable to install it to eliminate errors that were in previous version firmware and to improve the interaction and operation of devices (the so-called “hardware”) of the computer.
The BIOS can only be updated a certain number of times. In principle, this was true many years ago, back in the old versions of BIOS, which worked on the principle of outdated flash memory.
Now, BIOS manufacturers have made sure that bios can be updated more than a hundred times... so that’s enough updating for our time :)))
Although there will not be as many versions of updates. Manufacturers generally make no more than ten versions bios program updates, then tech. support for this model is ending.
Any computer equipment and software is known to become outdated over time and no longer meet current requirements. This equally applies to primary BIOS/UEFI systems, the software of which is integrated into a special chip on the motherboard. When installing new equipment (“hardware”), it may sometimes be necessary to flash the BIOS. This procedure will be performed on a laptop or a stationary computer terminal, it doesn’t matter. The technology is almost always the same. Some users, unfamiliar with the basics of such techniques, believe (and not without reason) that this process is unsafe and difficult. If you can agree with the first statement, then you can argue about the second. In fact, flashing the motherboard BIOS is not such a troublesome task. But to carry out this procedure correctly, you should pay attention Special attention some important details and nuances, which depend on the motherboard manufacturer and the programs and techniques used for flashing.
Why do you need to flash the BIOS?
In general, if it is not planned, and the entire system is working stably, update BIOS version basically there is no point.
But when new equipment is installed on a computer, which may not be supported by the primary system only due to its obsolescence ( Device BIOS it just doesn’t recognize it), flashing the BIOS becomes a pressing problem. Although many users find this process difficult, anyone who works with a computer can perform these steps on their own. It will take no more than 10 minutes.
Flashing the motherboard BIOS: prerequisites
First, pay attention to a few mandatory conditions, non-compliance with which can lead to catastrophic consequences.
Download files and programs to update primary systems only from official resources motherboard manufacturers. In case of installation unofficial firmware No one can give a guarantee that the process will be successful and the system will work as expected after that.
The second thing to pay attention to is during the update. You need to take care in advance to ensure that there are no power surges or spontaneous disconnection of your computer or laptop from the power supply.
General rules for updating all firmware
Flashing the BIOS for almost all motherboard models involves using the same scheme:
For standard systems BIOS in most cases uses DOS mode. However, for some BIOS versions, as well as for more modern systems UEFI may apply special program for flashing the BIOS, created by the motherboard manufacturer, which is capable of running even in an operating environment Windows systems without necessarily creating bootable media.
How to find out the modification of the motherboard and the current BIOS version?
The very first thing you need to do is determine which model of motherboard is installed in computer system, and also find out the version of the primary BIOS systems(maybe she's on this moment is current and does not need updating).
You can view information about the board and BIOS version in the section that is called from the Run console using the msinfo32 command.
For the motherboard you can use and specialized utilities like CPU-Z (formerly Everest). For a device identified in this way, you need to find the latest firmware on the manufacturer’s website and save the files on your hard drive.
Preparing bootable media (general procedure)
If you use bootable media, when an update from Windows is not provided, the first step is to create one. Regular recording of downloaded files will not work.
To simplify your work, you can use the Rufus utility, which is very easy to learn and creates bootable USB flash drive within a couple of minutes. There is practically no need to change anything in the parameters. Only in the file system should you specify FAT32, and in the recording method use MS-DOS mode, making sure to check the box next to the line for creating bootable media. If this is not done, then when you reboot the device will not be recognized as bootable. Then, to install the update, in some cases you will need to additionally copy it to media control program and the firmware file.
Next, the process of updating the BIOS will be discussed with examples for motherboards from several well-known manufacturers. Although in general they are very similar to each other, nevertheless, each of them has its own nuances. We assume that priority is BIOS settings already installed.
ASUS
Flashing the Asus BIOS can be done in several ways. Among the preferred utilities, two programs worth highlighting are AFUDOS and ASUSTeK EZ Flash 2.
When using the first utility, you should create bootable media and pay attention that it must contain the program file afudos.exe and the firmware itself (for example, p4c800b.rom).
Flashing the ASUS BIOS looks like this. Booting from a flash drive. Since the media was recorded for DOS mode, the initial line C:\> will appear on a black screen, in which you need to enter the command /i p4c800b.rom and press the enter key. Once the update is complete, a reboot will occur, during which you just need to remove the media from the USB port so that the system starts from the hard drive.
Flashing the BIOS of an ASUS motherboard when using the second utility is somewhat different from the previous option.
Despite the fact that most firmware on the official ASUS website have the .rom extension, CAB files can sometimes be found. There is nothing wrong with this, since they are used for UEFI systems.
To install the firmware you need to log in UEFI settings When rebooting, go to Advanced Mode ( additional settings) and in the service (tools) section of the Tool, select the line ASUSTeK EZ Flash 2. Next, from the list, again select the media with the program (line of the same name), after which the required firmware file will be shown on the right. We select it and agree to the warning twice (first to check the file, then to start the firmware process).
At the end of the process, a reboot notification will appear, and at the beginning of the restart, a proposal to carry out initial setup. Press F1 and set the required parameters. Otherwise, we simply exit the settings without saving the changes.
Gigabyte
Flashing the BIOS of Gigabyte systems is quite different from other processes. First of all, this is due to the fact that you can use online update to install the firmware. But first, let's look at using the Q-Flash utility, which is believed to be best suited for updating firmware.
First, you should enter the BIOS settings and use the option to reset all Load Optimized default settings. After this, you need to save the changes, restart the computer and enter the BIOS settings again. Next, to launch the Q-Flash utility, press the F8 key, and the start is confirmed by pressing the Y and Enter keys. To begin with, it is recommended to save the current version using the Save Bios option, after which you need to use Update Bios. Next, you will be asked to indicate the source from which you want to update. You should select HDD 2.0 as the media (this is how the flash drive is displayed in the settings). Then everything is as usual: select the firmware file present on the media and agree with all the warnings.
For an Internet update, you can use the @BIOS utility specially developed by Gigabyte specialists, which runs in Windows environment. In this case, it is strongly recommended to disable Hyper-Threading mode in the settings of the primary system, as well as deactivate anti-virus and other resident applications to avoid errors or failures during the update process.
After starting the program, you can immediately save the current BIOS version by clicking on the Save Current BIOS button, and then select the Internet Update online update mode, click Update New BIOS and specify one of the servers present in the list. After this, you will be asked to indicate the model of the installed motherboard, and the program will automatically download all necessary components and activates the update process.
MSI
Flashing the MSI BIOS, as in the case of ASUS, can be done either from Windows or from DOS. For DOS mode, a tool built into the BIOS called BIOS-MFLASH is used. But as a starting point management utility application can also be used MSI Live Update 5 or 6. It is notable for the fact that with its help you can also update everything installed drivers MSI, as well as reflash the BIOS of the corresponding graphics accelerators. Let's start with it.
In the main window you just need to check the boxes necessary elements. Select the MB BIOS component and click the scan button at the bottom (Scan). If a new firmware version is detected, use the Download and Install button, after which the update process will start.
First you will need to select an update environment. To simplify matters, check the In Windows mode, in the next window, click the button to close all programs that appear in the list (Close all listed programs), click the continue button (Next) and in the next window, click the button to start the process.
For DOS mode, select it from the window running process update, after which we indicate the media and agree to the destruction of all data present on it (the process will take no more than a minute, after which a message about successful creation boot drive). When rebooting, all you have to do is follow the instructions of a kind of “Master”.
In case of updating using the built-in MFLASH mechanism, you will have to download the firmware manually, create bootable media and perform the same actions in the BIOS as described above (select the media and firmware file in the tools menu).
Acer
Flashing the BIOS of Acer systems is surprisingly much easier. You don't even need to create bootable media, although you will still have to format it in FAT32.
To install the update, a special utility called Insyde Flash is used, which is copied to removable media. At the same time, you need to copy the firmware file downloaded from the official website, which has the extension .fd and corresponds not only to the motherboard, but also to the laptop model, to the main directory of the program on the flash drive. Please note that the device must contain only one firmware file, otherwise the application will prompt you to flash only one of several. After running the utility while the power is on, you will be prompted to install the update immediately.
The second method is just as simple. First you need to completely turn off the laptop, unplug the cord from the outlet and wait until the power indicator stops blinking. Next, plug the cord into the outlet, insert the flash drive into the appropriate port, hold down the Fn and Esc keys and press the power button. As soon as the indicator starts flashing, release the pressed keys. After this, reading information from the drive will begin (this can be seen by the blinking LED on the device itself). Once the update process is complete, the laptop will reboot on its own.
Video cards
Since GeForce and Radeon are dominant in the video card market, flashing the BIOS will be considered using their example.
At the initial stage, for your card on the manufacturer’s website you need to download new firmware and management programs. If the system has several video cards, you need to leave only one during the update, inserting it into the PCI-Express slot.
For GeForce cards the NVFlash program is used (from two files), for Radeon - the ATIFlash utility (one file). Next, you need to create a bootable USB drive for DOS mode, and then copy program and firmware files to it.
When starting from a flash drive, you should make sure that the card is single-processor, otherwise the proposed method will not work. For NVIDIA use the command nvflash --list, for ATI - atiflash -i. If information is displayed for two cards, then the adapter has two processors, and the proposed firmware method cannot be used (it is better to go to the manufacturer’s website and find instructions there).
The next step is flashing the BIOS GeForce video cards involves disabling protection. This is done with the line nvflash -protectoff.
Next, to start the BIOS update process for GeForce cards, use the command nvflash -4 -5 -6 newbios.rom (the name of the ROM file must match the name of the downloaded firmware), for Radeon cards - atiflash -p -f 0 newbios.rom. After this, we wait for the process to complete and reboot the system in normal mode.
Brief summary
That's all for flashing the primary I/O systems. Based on the above, we can conclude that the best option is to install the update exclusively in DOS mode, although special utilities can be used to simplify the work. But they only work if there are UEFI systems, and for standard versions BIOSes are no good. You need to be extremely careful with video cards, because incorrect installation update or the slightest violations during the flashing process can lead to graphics adapter will fail.
BIOS is a set of microprograms that connect existing hardware to the operating system. They are written into the chip and are actually “installed” by the manufacturing company. The user, in turn, can configure, update or reinstall the BIOS if an error occurs.
The type of BIOS varies depending on the motherboard and directly affects the performance of the computer. Therefore, if the motherboard was purchased at an authorized point of sale, all possibilities basic system I/O are described in the attached data sheet. To enter the BIOS, carefully look at the boot screens until the operating system logo appears. We are looking for hotkey, which will appear in a sentence like “Press<клавиша>to enter Setup.” This could be Enter, Del, F8, F12 or others. Click it and see blue screen with numerous tabs and settings. One of the most common BIOS functions that you need to the average user– this is the priority of loading from devices. Most often it is used before Windows installation(or other OS) to gain access to installation files on flash or CD\DVD media. In most types of BIOS, the tab you are looking for is called “Boot devices” and is located in the “Advanced BIOS Features” menu section. You can enter any submenu using Enter, and at the very bottom you can read what this or that tab does. In the mentioned boot priority list, the first device will be the one assigned the value “First Boot Device”. Exit with the “Esc” button, remembering to select “Save and Exit Setup” to save the changes. In the sections of our BIOS we have the opportunity to:- change system date and time;
- configure parameters hard drives, read their description, track their condition and performance;
- enable 16- or 32-bit data transfer mode via PCI bus;
- find out summary data for the entire system (the “System Information” tab);
- enable/disable SATA controller;
- enable compatibility mode with older operating systems, such as Windows 95 and 98;
- write-protect discs;
- “overclock” components with manual entry parameters;
- enable or disable the network adapter;
- assign addresses to COM and other ports;
- configure USB;
- configure energy saving and PC power supply;
- obtain data on the temperature and rotation speed of coolers;
- configure the “Num Lock” key and the order in which system data is displayed before booting;
- set administrator and user passwords;
- update the BIOS from a disk, floppy disk or flash drive.
If during startup, before loading the OS, the computer emits sound signals– this is also the work of the BIOS. The program interrogated the devices and found a certain malfunction, which was encrypted in a specific “beeping” sound. Decryption codes vary depending on BIOS type, you can find them in the instructions for the motherboard or on the Internet.
Via update Motherboard BIOS boards can solve a number of problems:
If the problems mentioned are not alien to your computer, and you don’t know how to fix them, you may have only two options left: send your system unit for repair, where specialists will do everything quickly and efficiently, or try to reflash the BIOS yourself, at your own peril and risk. However, you should not update the BIOS just out of curiosity. If your computer or laptop is running smoothly, it is better not to change anything, since incorrectly flashing the BIOS can lead to damage to the motherboard.
Three ways to update BIOS
Almost all modern motherboards support flashing in the following three ways:
Each option has its advantages and disadvantages. This article will describe in detail all three methods, as well as the risks associated with updating the BIOS. However, the final decision on how to flash the BIOS of your computer remains with you.
How to reinstall BIOS from Windows
This option for updating the basic I/O system is the simplest and fastest. But experts strongly do not recommend flashing the BIOS in a Windows environment, since the system may freeze at the most inopportune moment, which can be fatal when updating the BIOS.
In order to flash the BIOS from Windows, you will need to find out the computer model number, the BIOS version that is currently installed, and acquire removable storage(floppy disk, disk or USB flash drive).
The PC model can be identified by looking at the label, which is usually located on system unit or at back cover, If we're talking about about the laptop. You can also see the model number in the “system information” section. This section can either be found in the Control Panel or opened using the msinfo32 command (Start - Run - msinfo32). There you will also see information about current version Your computer's BIOS.
Another way to find out which BIOS version you have is to look directly at the Basic I/O system menu. To do this, you should restart the computer and before the operating system starts loading, press the key to enter the BIOS menu several times (most often it is “delete” or the keys “F1”, “F2”, “F3” and so on). There you can see information about the BIOS version. Write down the data on a piece of paper. After this, you need to log out of the system by pressing the "Esc" key and wait for the operating system to load. After turning on your computer, you need to go to the website of your PC manufacturer and download the new BIOS version from there in the “Support”, “Drivers” or “Service” section. There you will probably need to enter the PC model number and operating system version in order to obtain the appropriate BIOS file. Naturally, it is worth checking the version number of the basic I/O system installed on the computer with the one offered by the manufacturer. If the site does not have a newer BIOS than yours, then there is no point in downloading and reinstalling it. Otherwise, the proposed file should be downloaded and installed in the same way as regular program. This will complete the BIOS update.
Reinstalling the BIOS using the Q-flash utility
As a safer alternative to updating in Windows, let's consider the procedure for flashing the BIOS using the example of a computer with system board, which is built into low-level utility Q-flash. Note that, depending on the manufacturer, the name of the utility can be anything, but the principle of its operation remains similar.
So, before we start BIOS update using Q-flash, you should create a bootable USB flash drive onto which you will write a file with a new version of the basic input/output system (it’s written just above where to get the file with the new BIOS version).
First, you need to format your existing flash drive as a file FAT system, since q-flash only works with media that have exactly this file system. To save time you can use fast mode formatting.
After you format the flash drive and write to it required file, you need to restart the computer without removing the USB drive from the socket and enter the BIOS. Once in the system menu, press the "F8" key and the interface will open in front of you q-flash utilities, with which you will reinstall the BIOS. However, before doing this, it is extremely important to save the old version of the BIOS in order to be able to return it if during installation new system problems will arise. To save the BIOS, you need to do the following:
- 1. Select “Save BIOS to Drive” and press the “Enter” key.
- 2. In a new window, select the medium where you want to save the information and press “Enter” again. This medium may well be a flash drive with a new “BIOS”.
- 3. B root directory flash drive you will need to enter a name for old version BIOS. The name can be anything.

Having created backup copy basic input/output system, you will again be taken to the main Q-flash window to begin updating the BIOS according to the following scheme:
After selecting “Update BIOS from Drive”, press “Enter”. A window will open where you select the flash drive with the new BIOS version recorded on it. After you select required file and press the enter key, the system update procedure will start. The BIOS will update fairly quickly, after which you can exit the menu and reboot the computer already running new version basic input/output system.
Updating BIOS in DOS
TO this method Flashing the BIOS should be used if the PC manufacturer's motherboard does not have a tool such as Q-flash.
To update the BIOS in DOS, you need to create a bootable USB flash drive and write a file with the new version of the system to it, as is the case with reinstalling the BIOS using the Q-flash utility.
.jpg)
Having written the necessary file, you need to restart the computer to start working in DOS environment. However, before this you need to go into the BIOS, saving the current version of the system and setting the computer to boot from a USB drive. For this purpose in BIOS menu You should go to the “Boot” tab, setting the initial boot from a flash drive. It will look something like the picture on the left.
After setting up the BIOS, press the Esc key to exit and the “Y” button to agree to save the changes. After these steps you will see line Dos, where you need to enter a command that will launch the flashing program. The command should look like this:
C:>File, where "File" is the name of the program file. If you do everything correctly, then after you press “Enter”, the program will check the file with the new BIOS version for errors and compliance with the PC model. After the verification procedure, you will need to press any key so that a window appears in which the system will offer to update the BIOS. Pressing the "Y" key will begin the process of updating the basic I/O system. At the end of the short procedure, the computer will reboot on its own and start working under the new BIOS version.
In general, there is nothing complicated about updating the BIOS. However, this process is dangerous because any failure during system flashing can “kill” motherboard. Therefore, there is no need to reinstall the BIOS unless it is absolutely necessary and you are confident that your PC will not turn off at the most inopportune moment.
