BIOS setup in pictures: step-by-step instructions on the correct parameters. Restoring default BIOS settings to factory defaults

24.09.2019 Errors

BIOS default BIOS: (Basic Input-Output System) the basic input / output system that is stored in the memory of the motherboard and is needed so that we can manage the hardware that is installed on your computer. When working with BIOS, many users experiment, try to set the settings they need, some need to boot from a CD-ROM to install the operating system, and who wants to boot from a USB flash drive, someone does not have a hard drive, and so on. And it often happens that there is simply no way to work with these changed settings, what should be done then?

Note: if you changed the BIOS settings in such a way that you can't even get into it, read on.

The very first thing, if you change the parameters in the BIOS, it will be better to record all your actions. If you encounter problems with your computer, you can restore the original settings. But even if you got carried away in the process of work and, of course, did not write anything down, in any case, you can always return to the initial parameters. BIOS and make default settings specified by the manufacturer, for this you will have to use the Load Setup Defaults or Load Fail-Safe Defaults function. It will set the most secure BIOS settings, which will be optimal for normal system operation, and they will become what they were before your experiments.

BIOS default

So we are in the main BIOS window, then you need to go to the (Exit) tab, it is located from the (Boot) tab to the right after the (Tools) tab and is underlined in red. In it, using the arrows on your keyboard, select the Load Setup Defaults item, press Enter and go to the menu. Most desktop computers today are equipped with Ami BIOS or AWARD BIOS, and in this article we will mainly cover these manufacturers. By the way, everything that we describe can be used to configure another manufacturer Phoenix SETUP BIOS, it is mainly used on laptops.

Ami BIOS parameter Load Setup Defaults.

If the window is different, then this is an Award BIOS,

Here the parameter we need is called Load Fail-Safe Defaults, indicated by an arrow in the photo.

Both of them are configured in almost the same way. In Ami BIOS, we need to go to the (Exit) tab, it is located from the (Boot) tab to the right after the (Tools) tab and is underlined in red. In it, using the arrows on your keyboard, select the Load Setup Defaults item, press Enter and go to the menu.

Load Setup Defaults means loading the default settings (BIOS), that is, they will become what they were before your experiments, select OK and the settings are reset to default, remember this very necessary parameter, now do not forget to save your changes and exit the BIOS menu.

Note: if you changed the BIOS settings in such a way that you can't even get into it, read on.

Below, I will give several methods known to me to solve problems with resetting the motherboard BIOS and returning the BIOS to its original position. In fact, there is nothing difficult in this and in many cases it helps to avoid a visit to the service center.

1. Returning the BIOS to the factory default settings directly from the bios setup itself without disassembling the system unit. Suitable for resetting the parameters you previously set, will help restore bios settings, provided that the BIOS itself is loaded. How to do it? First you need to get into the bios setup menu.

To do this, you need to restart the computer, and during computer boot, when the logo of the motherboard manufacturer appears on the screen (not to be confused with the operating system logo), press the key to enter the bios setup. If you do not know which key is responsible for entering the BIOS, carefully look at the screen while the computer boots up when the logo appears, at the bottom they usually write in bourgeois which key to press. I have it Klashisha Del but you may have another.

After we entered the bios setup, we are looking for the parameters responsible for resetting the BIOS. Depends on the specific motherboard, maybe load bios defaults or F5, or maybe in another way. I think you'll figure it out, defaults is the default, that is, the factory settings. In any case, we are looking for a parameter with this word. Then you will be asked to confirm the changes in the same bourgeois, press Enter.

2. Reset BIOS to default using battery. First, you need to completely de-energize the system unit. Make sure that all cords are disconnected, this will save you from possible damage in case of careless actions. Remove the side cover of the system. Next, we are looking for the battery itself. It is rather difficult to confuse it with something else, it has a rounded shape and looks like a battery from a simple electronic clock. Its purpose is to maintain CMOS memory. It is necessary to remove the battery for 5-10 minutes, after which you can return everything to its place.

3. Resetting BIOS settings using a jumper (jumper). The jumper is usually located somewhere near the battery and is designated on the board as Clear CMOS or Clear RTS, abbreviations CLCMOC, CLRTS, etc. are also possible. There are times when motherboard manufacturers place a jumper at the edge of the motherboard for convenience. It consists of three contacts, two of which are closed. To reset the BIOS, you must move the jumper from position 1-2 to position 2-3, then return to its original position. If the strap consists of only two contacts, just bridge them with something for a few seconds.

And finally, if none of the BIOS reset methods suits you. Just disconnect the system from the power supply for several days until the battery runs out.

Instructions

The fastest and most convenient way to clear the BIOS is to use a special option that is built into it. Go to Bios. To do this, hold down the DEL key when starting the computer (sometimes these can be the function keys F1, F2 or F10). In the "BIOS setup" menu, find "Reset BIOS Settings". This option may have different names depending on the board model. Look for names like "reset to default", "factory default", "clear BIOS", "load setup defaults". Typically, this option is at the end of the menu, on the very last tab.

Select this setting and press Enter. The system will prompt you to confirm your choice and then reset all settings to factory defaults. This is often accompanied by exiting the BIOS and restarting the computer. If for some reason you cannot find this option, or you cannot enter BIOS, use other methods.

Method two. Make sure the computer is completely powered off. Open the side cover to access the motherboard. Find the SMOS battery (it's a coin-sized circular coin cell) and remove it. Removing the battery is easy enough - just grasp it with your fingers and pull it up. Some boards have a clip that holds the battery in place. In this case, bend the clip with one hand and remove the battery with the other. In this case, you need to be careful and not make excessive efforts so as not to damage anything. After 5-10 minutes, reinsert the battery and close the side cover of the computer.

Method three. Unplug the computer completely. Open the side cover to access the motherboard. Find the jumpers to reset SMOS. The exact location of the jumpers may vary depending on the motherboard. Ideally, you should consult the documentation. If documentation is not available, look for three or four jumpers near the SMOS battery.

Rearrange the jumpers. If your model has three jumpers, close the second and third, if four - the third and fourth contacts. Turn on the computer and make sure that the settings have been reset and the BIOS is cleared. Turn off your computer. Then return the jumper to its original position and close the computer cover.

In the BIOS menu of the computer, you can configure many parameters of operation: overclock the processor, adjust the fan speed, etc. But if you have just started to master the computer, then it is likely that you could get a little confused in them. And if you incorrectly set some parameters of the PC, then it is possible that the next time you turn on the computer, it simply will not boot. In this case, the best solution is to reset the BIOS settings to factory defaults.

You will need

- Computer with Windows OS.

Instructions

Go to the BIOS menu. Next, select the Exit tab. Several BIOS exit options will appear at the bottom, among which there should be Load setup defaults. Select this option and press Enter. Then select OK and press Enter again. The computer will restart. After a reboot, all BIOS settings will be returned to their factory defaults.

No battery. Then insert it back into the socket. The settings will be reset to factory defaults. Now you can close the lid of the system unit and turn on the computer.

Every computer technician involved in setting up and repairing a PC has more than once come across the fact that the computer begins to behave inappropriately or does not boot at all, giving out various errors and desperately feeding the system speaker. In such a situation, you often have to resort to at least the impact - resetting the BIOS, or rather even resetting the CMOS parameters. Any professional specialist knows at least 3 ways to reset BIOS settings to factory defaults.

Method one. Program.

Very often I have to turn to this method when the computer starts to "poke" and "flatten", the OS begins to swear with various errors and freeze. It helps to return the parameters to the factory settings, that is, to default. To do this, when you turn on your computer or laptop, press the button several times (to be sure) Delete... For laptops, the F2 button is used for this. So we find ourselves in the holy of holies, in the BIOS settings. There you need to search the sections for something like Load Defaults. As an example, I will give two of the most common BIOSes. Award-Phoenix BIOS has two items in the main menu - Load Fail-Safe Defaults and Load Optimized Defaults:

In fact, they are almost identical. I usually choose "Optimized Defaults". In the AMI-BIOS in the "Save and Exit" section there is an item "Load Setup Defaults":

Select it and get a warning window, in which you need to select "Yes". After rebooting, we get a virgin CMOS =).

Method two. Jumper (Jumper)

Each motherboard has a special jumper responsible for resetting the BIOS to factory settings. It is usually signed by CLR_CMOS or CCMOS. It is usually located somewhere near the battery on the motherboard. Here it is:

You just need to pull out the jumper from a pair of contacts and move one contact to the side. That is, he bridged the first and second contacts, but you need to switch it so that it closes the second and third.

Sometimes you can come across this option:

Here you need to bridge the contacts with a screwdriver or something similar.
After the necessary contacts are closed, turn on the computer, wait a couple of minutes and turn it off again. We return the jumper to its place and turn on the device.
BIOS has been cleared!

Method three. Battery

Another option is associated with the CR2032 system battery, which is responsible for the safety of CMOS data. There she is:

To return the BIOS settings to the factory settings, you need to pull it out for 15-20 minutes. How to do it? Press the clamp foot in the opposite direction to the battery, as shown in the photo:

After that, the battery should pop out of the slots. We wait 15-20 minutes and return it back. Reset

If you were looking for BIOS settings in pictures, then you have come to the right address.

The changes made will be protected by a lithium battery built into the motherboard and maintaining the required parameters in the event of a voltage loss.

Thanks to the program, it is possible to establish a stable interaction of the operating system (OS) with PC devices.

Attention! The present section of the Boot network configuration allows you to adjust the parameters related to the system boot speed, keyboard and mouse settings.

After completing work or familiarizing yourself with the Bios Setup Utility menu, press the burning Exit button, which automatically saves the changes made.

Main section - Main menu

Let's start with the MAIN section, which is used to modify the settings and adjust the timing.

Here you can independently configure the time and date of your computer, as well as configure the connected hard drives and other drives.

To reformat the operating mode of the hard disk, you need to select the hard disk (for example: "SATA 1", as shown in the figure).

Type - this item indicates the type of connected hard disk;
LBA Large Mode- is responsible for supporting drives with a volume of more than 504 MB. So the recommended value here is AUTO.
Block (Multi-Sector Transfer) - For faster operation, we recommend choosing the AUTO mode here;
PIO Mode - enables the hard disk to work in legacy data exchange mode. It is also best to choose AUTO here;
DMA Mode - gives direct memory access. Select AUTO to get a faster read or write speed;
Smart monitoring - this technology, based on the analysis of the drive's operation, is able to warn of a possible disk failure in the near future;
32 bit Data Transfer - the option determines whether the 32-bit data exchange mode will be used by the standard IDE / SATA controller of the chipset.

Everywhere using the "ENTER" key and arrows, the Auto mode is set. The exception is subsection 32 Bit Transfer, which needs to be fixed with the Enabled setting.

Important! It is required to refrain from changing the "Storage Configuration" option, which is located in the "System information" section and not to allow the correction "SATADetectTimeout ".

Advanced section - Additional settings

Now let's proceed to the settings of the basic PC nodes in the ADVANCED section, which consists of several sub-items.

Initially, you will need to set the necessary processor and memory parameters in the Jumper Free Configuration menu of the system configuration.

Choosing Jumper Free Configuration, you will go to the Configure System Frequency / Voltage subsection, here you can perform the following operations:

automatic or manual overclocking of the hard drive - AI Overclocking;
changing the clock frequency of memory modules -;
Memory Voltage;
manual mode for setting the chipset voltage - NB Voltage
change of port addresses (COM, LPT) - Serial and Parallel Port;
setting controller settings - Onboard Devices configuration.

Power section - PC power

The POWER item is responsible for powering the PC and contains several subsections that need the following settings:

Suspend Mode- set the automatic mode;
ACPI APIC- install Enabled;
ACPI 2.0- fix the Disabled mode.

BOOT Section - Boot Management

Here it is allowed to determine the priority drive, choosing between a flash card, floppy drive or hard drive.

If there are several hard drives, then the priority hard drive is selected in the Hard Disk sub-item.

The PC boot configuration is set in the Boot Setting subsection, which contains a menu consisting of several items:

Choosing a hard drive

The boot configuration of the PC is set in the Boot Setting subsection,

Quick Boot- acceleration of OS loading;
Logo full screen- disabling the splash screen and activating an information window containing information about the download process;
Add On ROM- setting the order on the information screen of the modules connected to the motherboard (MT) by means of slots;
Wait For 'F1' If Error- activation of the function of forced pressing "F1" at the moment of error identification by the system.

The main task of the Boot section is to determine boot devices and set the required priorities.

Attention! If you want to restrict access to the PC, then set the password inBIOS in subsectionSupervisorPassword.
