Dual BIOS Restoration Gigabyte UEFI Dualbios. Navigation by tabs in the main UEFI menu

Setting UEFI BIOS GIGABYTE to download from flash drives

Indeed, computers have long and firmly settled in our apartments and offices. And if you take into account the pathological passion of the Russian person to climb into everything by the slogan “Why should I repair something here?!”, I think everyone has the usual screen of special questions for a long time. Judge for yourself. significant changes in VBIOS have not brought whole decades. it all the time remained the same.

Several generations of people grew up on them, and they almost did not change at all. But still, evolution got to BIOS

The advantages and disadvantages of UEFI in comparison with BIOS

It is difficult to find a user who is notorious about a low.level BIOS program stored on the chip of a computer device motherboard. It has existed since the time of the archaic ms-dos. At the same time, the old woman-bios was improved not too actively and clearly without keeping up with the evolution of a personal computer, which led to the need to introduce a new generation of low-level. In 2007, the largest companies of Intel, AMD, Microsoft and computers have adopted a new UEFI specification and the Lion Fraction of PC, available today, applies advanced firmware instead of classical BIOS. It will not work to upgrade with BIOS on UEFI, since the software should be supported by the equipment. At the same time, reverse compatibility is present. most of the UEFI versions provide the ability to emulate BIOS, which may need users when installing not the latest OS, which involves the presence of BIOS.

  • Support for discs with a capacity of more than 2.2 TB, due to the use of the structure of the sections in the marking of the GPT instead of MBR.
  • Loading OS is performed much faster.
  • It is possible to have a graphic integration in various languages, mouse support.
  • There is a control manager of the OS that allows the device to load from drives that do not have their own booters.
  • The presence of a network driver, which allows UEFI to be updated without the need to start the operating system.
  • The possibility of expanding functionality due to the installation of third.party software and drivers.
  • Supporting safe launch Secure Boot.
  • Functioning over the network, which makes it possible to set up or debugging remotely.

On various computers, the UEFI integration and functionality may differ, many PCs work with new firmware today, but with the options and appearance inherited from BIOS.

  • No support for 32 discharge OS. It is possible to install an old or 32x.bit operating system in conditions of compatibility with hardware, by switching UEFI to the BIOS emulation mode, which at the same time will turn off many firmware functions.
  • HDDs with MBR markings are not supported (due to restrictions on the volume of the disk up to 2.2 TB and the number of volumes up to 4, the standard is displaced by GPT).

Lack of reaction

If after pressing the PC turning button does not make no sound, the fans do not spin, and the LED indicators do not glow, first of all, perform an external inspection of the power source, namely, check if the power wire is connected to the outlet and the connector in the unit, and whether it is also located power circuit breaker in the “vkl” position.

Next, check whether the power wires in the Material Code connectors were shaken. First open the body cover and see if the cables from the power supply to the motherboard are connected correctly. Disconnect a wide 24-pin connector and a 12-volt four- or eight-pin connector of the processor and inspect them. In case of contact of contacts, the case may be in the voltage jump or in the power supply malfunction. It is possible that this affected all the components of the system, which can lead to the purchase of a new computer.

The fault of the button. Steppiece both contact outputs of the power buttons (Power) on the motherboard using a paper clip to check the fault of the power button of the computer housing.

If everything is in order on the side of the power source, check whether the power buttons and reboots on the case are connected correctly to the motherboard and whether they have an easy passage. small dual.pin connectors should be firmly connected to contact conclusions. Disconnect the “Reset” button and try to turn on the computer (if it works, it means that the reboot button is faulty and should remain disconnected).

If this does not help, disconnect the power button. Further, if the system can be launched by closing both contacts, for example, using a paper clip, then the power button is faulty. In this situation, connect the reboot button and use it in the future as a “vkl/stop” switch. Otherwise, you will have to take the system unit to the workshop for diagnostics.

PC works, but the monitor remains off

If coolers and LED indicators work, but the image is not displayed on the monitor screen and it remains black, check its power source, and also make sure that the screen display settings are displayed by pressing the corresponding key. If not, then the monitor is faulty-this can be checked by temporary connection of another display (or TV using an HDMI cable).

If the screen menu is displayed, step over the entrances using the Source button or the corresponding point in the menu, until the desired connected input is set. Then run over the output modes on the PC on by holding the Win key and double pressing “P”. this allows you to switch to the next of four modes. Wait a few seconds and switch a total of four times to check if the image is displayed in one of the modes. If these actions do not bring results, replace the cable for the monitor and try another affordable integration (for example, HDMI or VGA instead of DVI) in order to exclude the malfunction of the connectors or cables.

Finally, the most time.consuming way is to check whether the installation or replacement of the video card will help (for starters it can be old or borrowed for the time of the video card). If all these attempts are unsuccessful, probably there is some other problem with the hardware that you can diagnose using the following actions.

Upgrade of a thin client Lenovo Thinkcentre M32 (part 2) ⁠ ⁠

We continue to finish the “foot support”, namely, in the first part we replaced memory, drive, processor and hub. In this part, I will add those functions that were conceived by the manufacturer, but in my configuration are unrealized. Namely, we will steam these two connectors:

One of them is responsible for Msata, the second mini PCI-E. There is nothing particularly complicated here, we clean up the landing sites:

And weave connectors with fasteners:

First of all, I will deal with MSATA, the necessary voltages come to the connector, and the disk is not determined. All because the capacitors along RX/TX are not soldered on the reverse side, through which there is communication between the hub and the disk. I steam them:

Well, the result was not long in coming:

I will not use this connector yet, in the future I will take free money for storing files (the usual 2.5 has nowhere to binary here).

We go to the Wi-Fi connector. Here the same, only the connector is unscrewed little. I am looking for his handout on the Internet and compare what is, what is not. I found out that only two capacitors are missing: C281 and C283.

I steam them and the module began to be determined in the system. But, I need not only Wi-Fi, but also a blue tooth. And for this it is necessary to connect the USB line to this connector. Only two resistors are separated from the connector: R336 and R337 (D and D-, respectively). I put nuleviki:

Краткий обзор UEFI биоса

Anten is also not provided here, so the collective farm is:

I collect everything, turn on, put the drivers and as a result:

I connect Yandex station for playback audio:

All that I need to work, on this upgrade can be considered complete.

The first (and last) test game is Need for Speed ​​Underground 2

Medium settings, FPS does not go far from 30 frames, temperature around 85 degrees. I tried to make the screen, it didn’t work out very much, so I decided from the phone:

Simple repair GTX 560 Ti⁠ ⁠

And again in my repair 560. Well, let’s take up the work. And so, a friend sent it to me, asking me to reject the GPU. After the Rebol, the card worked normally, but after some time everything returned to the original state:

And then vague doubts began to torment me that the matter was originally in the GPU. Made a memory test, as a result of which this memory chip turned out to be faulty:

Interesting, I thought and went for coffee, it was already about 2-3 hours.

Disassembled the card and drinking Cofi got to the desired memory chip:

But I’m not going to change yet, I’m wondering why after a Rubol GPU the card worked normally. I Gray a chip at 150 degrees with a minimum stream (not to heat the GPU) a couple of tens of seconds. I quickly collect the map and start the test stand:

The difference is already visible in the bios. Well, we will change the first memory chip.

We disassemble the card again and throw it to the soldering station:

Then we wash and suck the map:

We apply thermal grease, collect it completely and run the memory test again:

We launch the system, put the drivers and test:

Here everything should be, everything is fine, without artifacts and the like.

Having tested enough, I send it to the owner, where, I hope, she will last a long time.

How to restore Dual Bios Gigabyte. Useful FISHKI

June 2, 2016 Artyom Yushchenko

Hello dear friends, Artyom with you.

Today I will talk about how to restore the BIOS Dual BIOS on the motherboards of Gigabyte.

Once the motherboard stopped loading correctly. When launching, the system tried to automatically go to BIOS, but the integer did not draw, hanging. After which the motherboard went into a cyclic reboot.

I will show everything on the example of the Gigabyte GA-Z68A-D3H-B3 board

On the motherboard with two BIOS chips, one of the chips contains a backup copy of the firmware. It is this copy that you can use.

The essence of the operation is to close the first and eighth contact of the reserve bios chip, at the start of the system. Close contacts only on the chip marked with the letter m! In no case do not close the contacts on the microcircuit marked b!

For these purposes, I used a circuit with two metal needles at the ends. There are several attempts to get at the right time to start the recovery process. That is, you start the computer and literally after a second close the contacts.

Constantly shift the time, making the process of closure either a little earlier or a little later. In case of success, a window will be displayed on the monitor with information on the restoration of the BIOS from the reserve chip.

This method does not help everyone, but as they say, hope dies the last. And this method helped me, so I did not have to sew microcircuits through the programmer.

In more detail about the whole process, you can watch in the video video.

Be careful! You do all operations at your own peril and risk!

How to roll back BIOS

Before starting a review of the failure methods, we consider it necessary to mention that not all “motherboards” support this opportunity, especially from the budget segment. Therefore, we recommend that users carefully study the documentation and features of their boards before starting any manipulations with it.

Roughly speaking, there are only two methods of bias firmware failure: software and hardware. The latter is universal because it is suitable for almost all existing “motherboard”. Software methods are sometimes different for boards of different vendors (sometimes even inside one lineup), so it makes sense to consider them separately for each manufacturer.

note! You perform all the following actions at your own peril and risk, we are not responsible for the warranty violations or any problems that will arise during or after performing the procedures described!


ASUS system boards have a built.in USB flashback function, which allows you to roll back to the previous version of BIOS. We will use this opportunity.

Performing Clear CMOS

If BIOS flew off, but how to restore it on PC, the user does not know, experts recommend that Clear CMOS be performed. For this, the first thing to find on the surface of the motherboard is three grouped contacts, near which are the phrases of Clear CMOS or CLR_CMOS. It will be easier for the user to find the mode if he first familiarizes with the operating manual for the motherboard. There will be a jumper on these conclusions, closing the contact between them. It should also be taken into account that there are those that have only two contacts, without any jumper.

  • Turn off the computer.
  • Find the battery on the motherboard. This is a round battery, similar to an element from a wristwatch located on the surface of the board.
  • Carefully remove her from the outlet, where she is.
  • Before restoring the BIOS that flew, the position of the jumper is closed, which closes the chain between the two contacts. If contacts 1 and 2 are initially closed, then the position is set so that contacts 2 and 3 are closed.
  • Find the conductive metal surface and manually closes the chain between the two contacts. A flat head screwdriver is a great choice for these purposes.
  • After this step is performed, a circuit is left closed for at least 30 seconds.
  • After this time, the same actions are performed, but in the reverse order.
  • If everything went right, the system will start with the default BIOS settings.

How to restore BIOS on Gigabyte

If the Gigabyte motherboard support Dual BIOS technology, then restoring the BIOS will not be difficult.

If something happens with the firmware of the main microcircuit, the reserve BIOS immediately takes control of the load on itself and the question of how to restore BIOS, is automatically solved

When starting a system with a motherboard based on Dual BIOS, however, difficulties may occur. They are associated with three factors:

Some Gigabyte boards can boot with a reserve flash memory, and then use it as the main.

Other Gigabyte motherboards use a reserved area that is stored on a hard drive. In the latter case, BIOS recovery is automatically made from a backup

If the BIOS automatic recovery does not occur, you need to turn off the PC, then. extract the plug of the network filter from the outlet and wait about ten minutes. Turn on the computer again. the BIOS should recover automatically.

How to restore BIOS on msi

The restoration of the bios on the Micro-Star motherboards is practically no different from the restoration of BIOS on the ASUS maternity warehouses.

Восстановление UEFI BIOS на GIGABYTE c Dual Bios – Hackintosh Bios Ozmosis

The restoration of BIOS on the MSI motherboards is as follows: BIOS is copied to a formatted flash drive (you can also use a diskette or optical disk). The flash drive is connected to a USB port. Click and hold the PC shutdown button, at this time we press and hold the ALTCTRLHOME combination (or the left Ctrlhome). without releasing all the key.pressed keys, you need to turn on the computer

If the flash drive or drive indicator began to flash, then the installation procedure has begun and the problem how to restore BIOS will soon be solved.

BIOS on some MSI motherboards (especially the old ones, which for more than ten years) can be relying exclusively with disks. The procedure for the motherboard Award and Ami BIOS will differ. To restore Ami BIOS, you need to download a BIOS file from the MSI website.

You need to change the name at the downloaded file. we rename it in amiboot.Rom. Now this file must be copied into the root of a formatted diset. The floppy disk is installed in the appropriate drive, but only in the turned off PC. Then you need to simultaneously press and hold the combination of Ctrlhome keys, and then turn on PC.

Award BIOS restoration is as follows: BIOS and firmware files (usually they go together in the archive) are recorded on the diskette. We create a text file on the diskette-in it you need to prescribe the name of the BIOS file and assign it to it bin-explosion. Now this file needs to be assigned a new name. autiexec.Bat. Next. we perform the actions that were given above

Some motherboard manufacturers are allowed to update the BIOS by downloading the corresponding EXE-file, which is published by the manufacturer on the motherboard website. Such a file includes not only BIOS, but a questioner file.

[Adace-AD at first glance-everything is simple, but in practice-far from always. The main problems may arise with the fact that in such archives it is difficult to separate the firmware file from the BIOS and the firmware.

In some cases, the EXE-file can be unpacked as an archive, but even in this case to understand what is the firmware and what bios is very difficult. To solve this problem, it is better to create a tick in support, on the site of the producer of the motherboard

Some motherboards allow you to restore BIOS only after extracting RTC (editor note: we are talking about a clock battery) or after removing CMOS jumper.

Features of BIOS recovery on laptops

On laptops, as well as on Gigabyte boards, BIOS is also often stored in two flash memory chips. But this is not Dual and he does not have backup copies. Both chips contain different parts of the firmware or in one is the main BIOS, and in the other. the multicontroller program. So that the device does not turn on, it is enough to damage the microcode at least in one of them.

The methodology for the restoration of the flying BIOS’A on laptops is about the same as on desktops. The firmware file downloaded from the manufacturer’s website and the quilting program (the latter is not always needed) is placed on clean, formatted in FAT32/16 flash drive, connect it to the de-energized device (just turning off the laptop is sometimes not enough, you need to disconnect the power supply and remove the battery), insert it charged battery in place, turn on the device and clamp the key combination. Different laptopes use various keyboard combinations for this, for example:

  • Ctrl (only left or both) Home
  • Windows B (this and other letters are given in the Latin layout)
  • Windows f
  • Windows m
  • Windows ESC
  • Fn b
  • Fn f
  • Fn m
  • FN ESC.

The main work is to unpack and rename bios files. There is no single rule here, again. In most cases, you have to get firmware from EXE-shnaks, but! Many manufacturers include the BIOS’S program for different revisions of one platform or a whole series of platforms, and choosing the only necessary file from them is very difficult. In order not to make a mistake, read the instructions for the firmware of your model and the audit of the platform on profile forums. And feel free to ask questions.

I deliberately do not bring in the article instructions for restoring BIOS ’by firmware on a programmer with and without, close up various contacts, hot replacement of removable flash memory, etc. D., since all these methods are unsafe and require certain knowledge. However, among readers, probably, there will be those who did something similar on their PC and got good results. It will be great if you describe in detail your actions in the Комментарии и мнения владельцев on the article. Stories about negative experience are also welcome so that other readers thanks to you can avoid mistakes. In the Комментарии и мнения владельцев, be sure to give the name of the model and the audit of your motherboard, as well as the BIOS version with which you worked.How to restore the BIOS of a computer and laptop if it flew up updated: February 5, 2021 by the author:

Reset can also be useful when Windows does not load or the computer works unstable. If the listed problems arose after changing the parameters of the BIOS or failure in the firmware, then these instructions can help you.

Recall, BIOS is a software environment that controls the basic functions of a computer and is a link between the hardware and the operating system. After reset, the files on the drives and the Windows settings will remain untouched. But, most likely, you will have to go to BIOS, find a section with time and date parameters and rectify them again.

All of the listed methods of reset are suitable for both desktop computers and laptops.

What are the fundamental differences between UEFI and BIOS

In order to completely see the whole picture of the differences between the BIOS and UEFI, you should look at the list of functions that have changed. Below the article of the article is a list of the largest changes in the new version of the UEFI BIOS.

This is far from the entire list of innovations that UEFI received, but only a small part of them, which, in turn, has a great influence on improving work in this environment and directly among a personal computer, as well as in setting up UEFI Bios.

What is Dual BIOS

Dual BIOS, as you can understand from the name. this is a double BIOS. That is, on the motherboard of microcircuits with a bios two. Two bios. This is done, as manufacturers say, for safety. On my motherboard it looks like this (the “main” BIOS is circled by green, “spare”. blue):

Dual BIOS (double BIOS) on the GA-X79-UD5 motherboard

  • I flash the BIOS for some kind of horseradish and flash it unsuccessfully, so much so that my computer simply does not load.
  • I am in horror, but I understand that I have two BIOS.
  • I copy in the place of the “killed” BIOS BIOS from the second microcircuit, which was originally working and stored as a backup.
  • “Curve” BIOS was rubbed normal and Valya. everything is loaded as it should.

Also on some maternityics (including my GA-X79-UD5) on the rear panel there is a BIOS switch button that allows you to load the right. The button has two provisions:

  • M_bios (Main BIOS, the main one, when activating, glows green)
  • B_BIOS (Backup BIOS, Reserve, when activated it glows blue)

So, given all this information, it can be assumed that we are well protected from BIOS crash. But no.

BIOS, Dual BIOS in motherboard. what is it and why: 1 commentary

Gigabyte GA-G41MT-S2 Maternal board closed the CLR CMOS conclusions. So what’s now ? There is another PC and USB Flash Eeprom Programmer. Downloaded the program version 1.3 but I don’t know if it is suitable. Which of the 2 microcircuits to fall out and flash separately by the programmer ? Main BIOS ?

M_BIOS (Main BIOS) and B_BIOS (Backup BIOS) contain full firmware. The same or not. depends on the case, and this is not fundamentally. The work board starts with m_bios, the presence of only this flash drive is enough. According to the processor. Revisions of P55.US3L Plates I see 5 pieces. Whether this processor is supported by your version of the board, and if so. with which version of the BIOS? And flashing the latest version for this board could be immediately, before creating the topic.

How to roll back BIOS backwardly

Time flies on a netbook⁠ ⁠

There is a netbook of ASUS EEE PC 1215p on a motherboard 1215n/VX6 Rev 1.5 who, when starting, constantly flies a date and time

In February of this year, the BIOS battery changed and until recently everything was fine.

No downed elements on the board were found.

There is a multimeter, an oscilloscope, a soldering station, straight arms and a decent experience, but this case has faded me.

Hello, Ben, this is Danila. Ay Ned Help! (flew bios) ⁠ ⁠

Hello guys-picabushniki, help me figure it out, please.

To the point. I came into a wonderful (no) evening home and could not turn on the computer (I turned it off before that without perversions, as usual). The computer is old but pulling Skyrim and heavy Excel files, but I don’t need more.

After several unsuccessful clicks on the power button on the system, I tried to turn off and turn it on the toggle switch on the rear panel. Perhaps this became my fatal mistake. Nevertheless, after that he turned on and issued the following: “Recovery Bios Request”, insert a floppie or a flash drive.

What was done:- downloaded BIOS firmware with off.Maternker site, recorded on a USB flash drive (threw 2 files from a downloaded archive), the flash drive is formatted on FAT32. did not help;- replaced batteries in the mat.board. It did not help;- a boot flash drive was created using Rufus programs, then the firmware files are thrown onto it. did not help.

The computer sees a flash drive, but writes that the necessary files on it were not found.By the way, there is still a nuance: on the gland itself.Plates Model H55M-E33, and on top of the H55M-P31 sticker. I tried the firmware for both (judging by the type of board. The sticker is closer to the truth). MSI board manufacturer. Flash drives of 2 and 4 Gb. I dismantled the computer. visually burned sectors for nothing.

I will be glad to advice and your experience! Yutub and Google did not help me 🙁 I tried to call PC masters out of 5 accessible in my city, everyone sent me, because they did not know how to be.

Thanks in advance, I am attaching Комментарии и мнения владельцев for the minuses.

According to the rules of the community: my level. I am a girl, but I am friends with a computer; I will know a photo, if necessary; equipment. Sprinkle and enthusiasm.
