How to reset the BIOS on the motherboard to factory settings

A computer is a complex conglomerate of software and hardware components. The fact that it works almost flawlessly is also due to the BIOS - the firmware, which is precisely responsible for testing the PC hardware at the moment it is turned on. The BIOS stores many settings that determine how the operating system should use its hardware, and these settings can be changed.

Still, some computer problems can be caused by incorrect settings stored in the BIOS. In such cases, the most effective way to restore stability in your PC is to restore factory settings.

Such an operation may be required in the following situations, which are by no means hypothetical:

• when overclocking CPU/GPU. Many users take advantage of the ability to increase processor performance built into them by the manufacturers themselves. Overclocking is not always safe: under unfavorable factors (high outside temperature, increased load on other PC components), the processors will overheat, which will automatically lead to computer malfunctions;
• in case of unsuccessful firmware update, performed knowingly or unknowingly. If a BIOS version of dubious origin was used (downloaded from unreliable sources), there is a high risk that the normal operation of the computer will be lost. To prevent it from getting feverish, you will have to reset the BIOS to factory settings;
• Of course, many other PC problems, such as freezes, frequent unauthorized reboots, startup problems can also be associated with the BIOS, and resetting it to the initial factory level often helps solve such problems.

Today we will look at how to perform this operation, since there are several ways to perform a factory reset. All these methods can be divided into two broad categories: soft reset and hardware BIOS recovery.

Instructions on how to translate your BIOS into Russian

If you are a confident PC user, you have probably encountered a problem when your computer breaks down or stops working exactly the way you need it. It is difficult to imagine life now in which there would be no need for a personal computer. As soon as a user encounters such problems, he immediately begins to look for a solution to this problem. And it often happens that you have to fix the problem yourself. The more complex the breakdown, the greater the difficulty in repairing it. But what if, in order to eliminate the consequences, you have to contact the BIOS, the descriptions of which in your native language are quite small? It is for such cases that information is provided with which you can understand what BIOS is in Russian.

What is BIOS?

Main BIOS settings window

BIOS, or BIOS, is a program that is standardly written to a memory chip belonging to the EEPROM standard (stands for Electrically Erasable Programmable Read-Only Memory, literally in Russian - electrically erasable programmable read-only memory device). With the same success, the BIOS is written to flash memory, which is almost the same as a memory chip. It is the BIOS that is used by the computer immediately after startup.

The task of the BIOS is to recognize the device. Such devices may be (this is important to know):

• disks;
• video;
• CPU;
• memory.

How can a user interfere with the BIOS?

There are several ways to interfere with the BIOS, or rather, reasons why the user interferes with the system. For example, there was a need to reflash the BIOS. The user erases the contents of the microcircuit, and then independently records the updated content. These actions are carried out to improve the code. The rewritten firmware eliminates previously made errors.

The second scenario is not so complex and much smaller in scale, although choosing this path gives the user many opportunities. New parameters are simply introduced, replacing the old ones that are given to the machine when the system starts, be it in Russian or English. For any system, to make such a change, you only need to click the button offered by the computer when starting the system (for example, “Press Del to enter Setup”: this inscription may be in Russian, although more often it is found in English). After this, the phrase “Entering Setup...” will appear (you will rarely see it in Russian either), and then the BIOS management interface will pop up.

Standard CMOS Features

Fig.2: Standard BIOS settings

Date

Date format: <day of week>, <month>, <date>, <year>.

Day of the week - the day of the week is determined by the BIOS based on the entered date; it cannot be changed directly.

Month - the name of the month, from January to December.

Number is the day of the month, from 1 to 31 (or the maximum number of days in the month).

Year - year, from 1999 to 2098.

Time

Time format: <hours> <minutes> <seconds>. Time is entered in 24-hour format, for example, 1 o'clock in the afternoon is written as 13:00:00.

IDE Primary Master, Slave / IDE Secondary Master, Slave (IDE Disk Drives)

This section defines the parameters of the disk drives installed in the computer (from C to F). There are two options for setting parameters: automatically and manually. When defining manually, the drive parameters are set by the user, and in automatic mode, the parameters are determined by the system. Please note that the information you enter must match your drive type.

If you enter incorrect information, the disk will not work properly. If you select the User Type option, you will need to fill out the items below. Enter data using the keyboard and press . The necessary information should be contained in the documentation for your hard drive or computer.

CYLS — Number of cylinders

HEADS — Number of heads

PRECOMP — Write precompensation

LANDZONE - Head parking zone

SECTORS — Number of sectors

This setting determines which errors will stop the system boot when detected.

NO Errors The system will continue to boot despite any errors. Error messages are displayed on the screen. All Errors Boot will be aborted if the BIOS detects any error. All, But Keyboard The download will be aborted on any error other than a keyboard failure. (Default setting) Ail, But Diskette Boot will abort on any error except floppy drive failure. All, But Disk/Key Boot will abort on any error except keyboard or disk failure.

Memory

This item displays the memory sizes determined by the BIOS during system self-test. You cannot change these values ​​manually. Base Memory The BIOS's automatic self-test determines the amount of base (or regular) memory installed in the system. If the system board has 512 KB of memory installed, 512 K is displayed, and if the system board has 640 KB or more memory installed, 640 K is displayed . extended memory. Extended memory is RAM with addresses above 1 MB in the CPU's addressing system.

How to reset BIOS settings

Let's look at the most popular ways to reset the BIOS to factory settings , which even a beginner can handle. Before carrying out operations, disconnect the computer from the network so as not to provoke short circuits or damage to spare parts. After turning off the power, you must wait at least 10 seconds before restarting.

Resetting BIOS Setup using the CLRTC jumper on the motherboard

In order to perform the operation, you will have to disassemble the system unit.

CLRTC jumper on motherboard

1. Remove the cover.
2. Find the motherboard.
3. On it, near the battery (which will be discussed below), you can see a small jumper.
4. It needs to be taken out and moved one notch to the right (it is better to use tweezers for this).
5. Press the power button (to discharge the capacitors).
6. Move the jumper back.
7. BIOS has been restarted.

The jumper looks like a small blue cube that switches between two positions. When restarting capacitors, you also need to wait 10 seconds before and after the procedure, otherwise there is a chance of failure.

We take out the battery

1. Disassemble the PC after first disconnecting it from the network.
2. Take out the battery (ordinary crown) next to the jumper.
3. Press the power button to restart the capacitors.
4. Put it back in.
5. BIOS has been restarted.

The battery on the motherboard sometimes needs to be replaced, since the metal is also susceptible to corrosion. If there are traces of rust or oxidation on the crown, feel free to change it, otherwise problems with the PC will inevitably arise.

Using BIOS Setup Options

This method is useful only when the user remembers the BIOS password.

1. When starting the PC, you need to press the DEL (or F8) key.
2. The BIOS menu will open.
3. You need to go to the “Exit” tab and select “Load Setup Defaults”.
4. After this, the system will restart and the settings will be returned to standard.

BIOS Setup Options

ATTENTION! If the user has installed a non-standard (custom) system assembly, its factory settings may differ from the usual ones. In this case, resetting may even cause harm.

Moving through the menu is done using the “Left” and “Right” arrows, and confirming and canceling actions using the “Y” and “N” keys, respectively.

Resetting BIOS Setup using the Debug utility

For this method you will need everyone's least favorite command line.

1. Press the Win+R key combination.
2. In the window that opens, enter “debug” (without quotes).
3. A command prompt will open.
4. Enter there: O 70 17 O 73 17 Q (for AMI BIOS or AWARD) or O 70 FF O 71 FF Q (for Phoenix BIOS)
5. BIOS has been restarted.

Debug utility for resetting BIOS settings
Contrary to popular belief, you can paste copied text into the command line. Only this is done not with the standard CTRL+V combination, but by right-clicking on the command line field and selecting “Paste”. If you enter data manually, you must observe all line breaks and spaces.

Jumper contacts with any metal conductor

The method will be useful for laptop owners.

1. Remove the battery.
2. Find the JCMOS pins on the surface of the motherboard.
3. Between them you need to place a metal object (master key, screwdriver) for a couple of seconds. The contacts will close and the settings will return to factory settings.

Boot Up Floppy Seek (Detecting the type of floppy drive at boot)

During the system self-test, the BIOS determines whether the floppy drive is 40-track or 80-track. The 360 ​​KB drive is a 40-track drive, while the 720 KB, 1.2 MB, and 1.44 MB drives are 80-track.

Enabled BIOS determines the type of drive - 40- or 80-track. Keep in mind that the BIOS does not differentiate between 720 KB, 1.2 MB, and 1.44 MB drives because they are all 80-track drives.

Disabled BIOS will not detect the drive type. When installing a 360 KB drive, no message is displayed on the screen. (Default setting)

Password Check

System If you do not enter the correct password when prompted by the system, the computer will not boot and access to the settings pages will be denied. Setup If you do not enter the correct password when prompted by the system, the computer will boot, but access to the settings pages will be blocked. (Default setting)

— based on the results of the POST procedure:

During the POST procedure, press the Pause/Break key on the keyboard. After pressing this key, the procedure is paused. From the information displayed on the screen you can find out the BIOS version (see Fig. 1).

BIOS (Basic Input/Output System) is a program stored on the chip and is designed for:

• ensuring the initial startup of the computer followed by startup of the operating system;

• performing the procedure for testing PC elements;

• support for I/O functions using BIOS software interrupts;

Many inexperienced users, when faced with the BIOS, are lost - there are many incomprehensible settings in an incomprehensible language. You can make the task a little easier by making the firmware interface in Russian. Today we want to introduce you to the available methods for Russifying BIOS.
