Bios for Android menu description. What kind of animal is this? Enter recovery using the Quick Boot application


To solve some problems with your computer, you may need to change BIOS settings. What is BIOS? The Land of Soviets will tell you about this.

What is BIOS?

BIOS (basic input/output system, basic input/output system)- This special program, which is stored in a read-only memory chip. The BIOS is required, in particular, for bootstrap computer. What are the main functions of BIOS?

The main functions of this program include:

  1. Initial testing of all computer components after power on (POST). If all elements are functioning properly, the BIOS transfers control to the program located in the boot sector boot disk- it loads the operating system.
  2. Storing the computer's hardware configuration in a special CMOS memory chip. When you turn on your computer, the BIOS compares the computer's current configuration with the last saved one. If there are differences in the configuration, the contents of the CMOS memory are updated. If updating the configuration without user intervention is not possible, the user is prompted to call the BIOS Setup routine to manually specify the parameters of the detected components. Users usually call this “entering the BIOS.”
  3. Manually specifying parameters and operating modes of computer components or disabling them (using BIOS Setup).
  4. Processing I/O operations.

All these BIOS features interconnected and complement each other.

In the mouth of an ordinary user, “entering the BIOS” means “run the BIOS Setup routine”. As mentioned above, this subroutine is used to configure the operation of individual computer hardware components.

To understand how to enter the BIOS, you need to understand . When we press the power button, the first thing we do is initialize and check the devices. First, the presence of a processor and modules is determined RAM. After this, the video adapter (video card) is initialized and checked. You can often see the video card parameters (type, memory size, etc.) on the monitor screen, but these messages may not be displayed.

Then the BIOS determines the amount of installed RAM and the type of processor and checks these devices. At the same stage, IDE/SATA devices, expansion cards (cards) are initialized and checked, and devices compatible with the Plug and Play standard are searched. After initializing and checking all devices, the following message is displayed: hardware configuration table(mostly BIOS versions), and the download begins operating system.

Typically, the system prompts you to enter the BIOS (in other words, run BIOS Setup) after completing the self-test (POST), at the time of initial initialization. In most cases, an inscription appears on the computer screen that prompts you to enter BIOS Setup (for example, Press DEL to enter SETUP). All you have to do is to enter, follow the instructions and press the Del (Delete) key on your computer keyboard until the inscription disappears.

Sometimes this message is not displayed. How to enter the BIOS in this case? You need to turn on the computer, and as soon as the keyboard initializes (this can be determined by the blinking of the Num Lock indicators, Caps Lock And Scroll Lock), press the DEL key several times in a row. Didn't work out? It is possible that your BIOS calls BIOS Setup using other key combinations. These can be the following keys and combinations:

  • F1 – for separate versions Phoenix BIOS
  • F2 – for certain versions of Phoenix BIOS and Intel motherboards
  • F10 – for certain versions of Phoenix BIOS
  • Ctrl + Alt + Esc
  • Ctrl + Alt + Ins
  • Ctrl+Alt

If these key combinations are not specified at boot, you can find in the manual for your computer or motherboard. However, the Del key remains the most common option. Sometimes pressing a key or key combination once is not enough to enter the BIOS. It's best to press a key or combination about 10-15 times over about 10 seconds.

We remind you what to change BIOS settings Not recommended unless absolutely necessary!

If you were looking for BIOS settings in the pictures, then hit correct 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 loss of voltage.

Thanks to the program, it is possible to establish stable interaction between the operating system (OS) and PC devices.

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

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

Section Main - Main Menu

Let's start working with MAIN section, used to modify settings and adjust timing indicators.

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

To reformat the operating mode hard drive, you need to choose hard drive(for example: "SATA 1" as shown in the picture).

  • Type - this paragraph indicates the type connected hard disk;
  • LBA Large Mode- is responsible for supporting drives with a capacity of more than 504 MB. So the recommended value here is AUTO.
  • Block (Multi-Sector Transfer) - For more fast work here we recommend choosing AUTO mode;
  • PIO Mode - Enables the hard drive to operate in legacy data exchange mode. It would also be best to select AUTO here;
  • DMA Mode - gives direct memory access. To get more high speed reading or writing, select AUTO;
  • Smart monitoring - this technology, based on an analysis of the drive’s operation, can 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 requires the Enabled setting to be fixed.

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

Advanced section - Additional settings

Now let's start setting up the basic PC components in the ADVANCED section, which consists of several sub-items.

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

By selecting Jumper Free Configuration, you will be taken to the Configure System Frequency/Voltage subsection, where you can perform the following operations:

  • automatic or manual overclocking of the hard drive - AI Overclocking;
  • change clock frequency memory modules - ;
  • Memory Voltage;
  • manual mode setting the chipset voltage - NB Voltage
  • changing 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 require following settings:

  • Suspended Mode- we exhibit automatic mode;
  • ACPI APIC- set Enabled;
  • ACPI 2.0- fix the Disabled mode.

BOOT section - boot management

Here you can determine the priority drive, choosing between a flash card, disk drive or hard drive.

If hard drives several, then in subparagraph Hard Disk the priority hard drive is selected.

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

Selecting a hard drive

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

  • Quick Boot– acceleration of OS loading;
  • Logo Full Screen– disable the screensaver and activate information window, containing information about the download process;
  • Add On ROM- setting the priority on the information screen of modules connected to motherboard(MT) via slots;
  • Wait For 'F1' If Error- activation of the function of forced pressing “F1” at the moment the system identifies an error.

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 your PC, set a password inBIOS in subsectionSupervisorPassword.

Open the computer lid and carefully inspect all its insides. Find motherboard. You need to carefully examine it and find the coin cell battery. Take it out and set it aside for a few hours (5-6 is usually enough).

Due to the loss of constant power, the data in the BIOS will return to its original values. The access password will also be reset. The next time you turn on your computer, simply enter the new settings.

Method No. 2

Some modern computers significantly simplify the user's task. They have special connectors next to the battery that allow you to clean BIOS memory without resorting to such drastic measures. You can see the exact location of these connectors in the instructions.

If you have lost the instructions, go to the manufacturer's website. Everything should be located there necessary information. When the computer is turned off, close these connectors. The data will be reset and you can enter new parameters.

Have a nice day everyone!

It is quite possible that most users of Android smartphones or tablets are unlikely to be interested in the topic of this article - “Is there a BIOS on Android?” For some, it may sound something like “is there life on Mars,” while others have a hard time imagining what this BIOS is and what it might be needed for. But, as it turned out, there is another is by no means a small category of people for whom this question arouses curiosity.

We can first advise you to get acquainted with a number of articles on our website, for example, you can read about “”. Instead of going into the by no means perfect Wikipedia, where you can read abstruse phrases like “part of the system software..." and in the end you don’t understand anything. There is no need to get into the technical jungle at all. Here you choose, we won’t interfere.

Why might this question arise?

But really, why could such a question arise? It seems to us that its roots lie in the fact that, ultimately, a smartphone or tablet, in the understanding of most people, is the same personal computer as the miracle unit standing on our desktops. It’s just that its work is based on the use of mobile and compact technologies. One of the names of a smartphone or PDA is Pocket Personal Computer. Yes, and the Android OS (Android is the Russian version) is an operating system that is based on Linux OS code, which is also easily installed on a home PC. And it would seem logical to assume that there is also a BIOS, since everything is so similar...

In addition, there is some software that allows you to perform a number of actions to restore the operation of a smartphone or tablet, but at the same time it does not work in the general OS shell.

This is our guess...

What can be mistaken for a BIOS?

Our PDAs and tablets have a number of functions that are performed by certain software, such as:

  • Recovering the screen unlock code or pattern;
  • Installing more recent firmware;
  • The need to do a HARD RESET (hard reset), because the operating system suddenly stopped loading, and the boot animation icon has been spinning for ages.

In home PCs and laptops, you can go into the BIOS and boot from a flash drive and solve a number of pressing problems without loading the OS. What about tablets and PDAs running Android OS?

Recovery Menu

And on Android you can go to a certain Recovery Menu (Recovery Menu - in conversation), which can solve the above issues.

There is no universal method that would be suitable for all devices without exception. Usually, those who want to enter the standard recovery menu are advised to hold down the volume up button when turning on the phone, and then press the power button. But if this method does not work in your case, then look online for a method that is applicable specifically to your model of Android tablet or phone.

Let's delve a little deeper into this tool...

“Stock” or “Custom” Recovery Menu

Usually, “native” or stock (slang, from the English word Stock – “warehouse”), that is, preinstalled by the manufacturer of the tablet or phone, the Recovery menu is not rich in functionality. And its main function is to return the device to factory settings. And although in some firmware Recovery is equipped with some additional functions, there is still a high probability that instead of contemplating the Recovery Menu, you will immediately get a Wipe (reset to factory settings). So before starting “experiments” with the device, it is better to make a backup of important data.

To significantly expand the capabilities of the recovery mode, you can install the Recovery Menu written third party developers or custom (slang, from the English word Custom - “customized” or “custom-made”). It will replace the standard menu on the tablet and provide you with many additional functions.

True, to be able to install Third-party Recovery Menu, on your device you must have root (Administrative) rights to work with the OS.

For example, the most popular alternative standard menu- This Clockworkmod Recovery or CWM for short. By installing it, you will receive these additional features How:

  • Ability to install various (including unofficial) Android OS firmware;
  • Restore the system from a previously created backup;
  • Clear ;
  • Debug Android (fix) - install various updates and additions yourself.
  • Format the memory card, as well as create new partitions on it.

And this is not the entire list of what you can get by installing the Custom Recovery menu. So if you don't care that much about your device's warranty (which is automatically voided after rooting), you can try out all the functionality of CWM.

Conclusion or answer to the question

Recovery Menu is not a BIOS as such. Unlike BIOS, Recovery Menu software is a set of programs that are not built into a separate one installed on system board smartphone or tablet chip, but are only located in a dedicated section on the same flash memory, next to all other software, and is an integral part of the Android operating system.

Here would be better suited analogy with Windows OS on branded computers, which creates a partition on the same disk backup recovery OS to its original factory state (if you did not make backups yourself). Same disk, same operating system, just allocated an area for backup copy and the shell for working with it. Nothing more.

And there is no more software on tablets and PDAs that is in any way similar in functionality to BIOS. Hence the answer: there is no BIOS on Android. :-)

Mobile devices have already become quite an integral part of our lives. Now a person cannot imagine existence without a smartphone or tablet. Devices based on the Android operating system are extremely popular. This OS was developed by Google, and now its market share is incredibly high. iOS from Apple and Windows Phone insignificant percentage of presence on mobile markets compared to Android. However, like all technology, devices on this platform tend to glitch. Various system crashes - distinguishing feature any operating system. No matter how advanced it may be. Very often devices have to be reflashed. But not everyone knows that you can do without such radical measures. After all, every Android gadget has Android. System Recovery 3e. How to use it and what is it even? This is what we will talk about.

What kind of animal is this?

What does it mean Android System Recovery 3e? This is a kind of BIOS mobile device. Any operating system has its own BIOS - basic system I/O that can work even if the main OS is damaged. Sometimes the BIOS is not similar to the standard one (as, for example, in Android devices). It serves to restore the functionality of a smartphone or tablet, apply critical updates or do a factory reset. The Android System Recovery 3e menu has many items that correspond to one or another action. But the trouble is that the names are written in English. Therefore, many people do not even know how to use recovery correctly.

That is why this article was written. Android System Recovery, the instructions for which are absolutely necessary, is powerful tool for setting up and resuscitating a smartphone. You need to know everything about how to use this recovery in order not to waste money on specialists. Doing everything yourself is much easier and cheaper. We will analyze each item in the recovery menu and tell you everything we can about it. So let's begin.

How to enter recovery?

It depends specific model devices. In some devices you need to hold down the power button and the "Volume +" key. But sometimes there are smartphones for which this is not enough. Old models with mechanical button"Home" requires pressing this button as well. Some devices require you to simultaneously press the power and volume buttons. There are also those who must hold down the power key and both volume buttons. This only applies original devices from well-known manufacturers.

But there are also frankly “Chinese” gadgets with an incomprehensible operating system and “crooked” translation. Standard Methods Logging into recovery may not work in these cases. There are several options here. First: study the smartphone documentation (if available) and find the key combination you are looking for. But this option is not suitable for everyone. Most of these devices either have no documents at all, or the documents do not contain Russian at all. Second option: find the desired combination by pressing all the buttons in turn. Now let's move on to the Android System Recovery 3e menu items.

Reboot system now

This menu item does full reboot devices. After selecting this option, the smartphone will load the standard Android operating system without any changes. Typically, this item is used after completing all manipulations in recovery. Or if you loaded into this mode by accident. Although it is unknown how this can be done accidentally. Be that as it may, Android System Recovery 3e, the instruction manual for which is simply vital for the user, has such a clause. And we have to take this into account.

The menu item should be used last. That is, when all operations are completed, all components are updated, factory settings are reset and firmware is installed. This is the essence of a reboot: to allow the device to apply all the changes made. True, after some of them the smartphone may not boot at all. But that's a completely different story.

Apply Update from External Storage

This menu item allows you to apply the update that is located on the memory card. By the way, new firmware is also installed through this point if the main OS does not boot. There are several sub-items in this Android System Recovery 3e menu. How to flash a new OS? To do this you need to go to this menu and select Choose ZIP from SD Card if the firmware is in ZIP format. If this is just an update file, then you should select Apply Update From SD Card. This is how any device is flashed using recovery. Simply copy the firmware file to the root of the memory card, go into recovery and select the desired item.

This paragraph has other subparagraphs that apply in non-standard situations. It is possible to check the MDSUM of the firmware file. This option checks the file for integrity and if something is wrong, it immediately issues a warning. You can also check the firmware file for compatibility with the device. These are the informational options of Android System Recovery 3e. Instructions as such are not required for them. If there are errors, then put this firmware no need. That's the whole story.

Wipe Data. Factory Reset

This is very important point. This option can restore the functionality of the device without any firmware. This tool resets the gadget's operating system to factory settings. Naturally, everything that was on the smartphone will be deleted: applications, photos, music. In general, everything that was in the internal memory of the phone. Android System Recovery 3e, the operating instructions for which are discussed here, was created precisely in order to revive the device without serious intervention in the firmware. And this option allows you to perform this operation.

This function is also used before installing any firmware. It is necessary to reset the phone to factory settings before flashing the firmware. Otherwise, the new operating system will be unstable. But that's not the worst. If you do not return to the factory settings, the firmware may not be installed at all, and then the user will receive a completely “dead” smartphone. There are no instructions in Russian, but the one that is there clearly says what to use Wipe Data & Factory Reset It is necessary before each device firmware update.

Wipe Cache Partition

One more useful command in Android System Recovery 3e. The recovery instructions say that you need to use this option in tandem with Wipe Data. If the previous paragraph clears internal memory device, then this clears its cache. Namely, this is where the working application files are stored. Of course, if this is not done before installing the firmware, then nothing bad will happen. It’s just that in the future, when installing new programs, the device’s cache will grow to incredible sizes. As a result, the smartphone will work very slowly. But this is not so scary, since there are many programs for clearing the Android OS cache. And they work great.

It is also recommended to select this function after a factory reset has been done. This will help the smartphone become even “cleaner,” which will have a positive effect on the performance of the operating system. The instructions in Russian for Android System Recovery 3e recommend performing this procedure after the reset. Before rebooting the device. Then everything will be as it should be.

Wipe Battery Stats

This feature helps you refresh your device's battery. After clicking on this item, the battery cache begins to be cleared, into which the current state of the battery, its nominal capacity and other necessary parameters are recorded. Resetting usage statistics battery, it will be possible to extend her life a little. Yes and new firmware will work more adequately with the battery. For some reason, many Android “gurus” are dismissive of this option. But in fact it is very useful. However, it is not recommended to use it too often. Only before flashing the device.

Mounts. Storage

Here are the controls for the internal and external memory smartphone. This item allows you to clear a memory card or built-in memory, format it or attach it as a drive directly from recovery. This section can be used if you forgot to transfer the firmware file to the memory card, and there is no desire to reboot your smartphone into the operating system. In order to mount the device’s memory card as a drive, you need to select Mount USB Storage. Once the connection is established, the computer itself will establish necessary drivers for work.

Once the connection is established, you can do whatever you want with the memory card: format, clear, copy necessary files and so on. In order to unmount the flash drive, you should select the Umount USB Storage item on the smartphone screen in recovery. After this, you can move on to other recovery points and carry out further resuscitation of the device on your own.

Recovery errors

Sometimes there is such a common error in Android System Recovery 3e as canceling the installation of the firmware or package. It can occur for several reasons: the firmware file is damaged, incorrect information in the binary file, or the firmware simply does not suit this device. But there is another option: before flashing the firmware, the device was not reset to factory settings. It’s good that they can be easily fixed in the same recovery. There are several ways to do this.

So, if the error occurs due to broken file firmware, you should download it, connect your smartphone to your computer, go to the Mount & Storage menu item and select Mount USB Storage. After this, you can copy the firmware again to the root of the memory card. If you forgot to “wipe”, then there is nothing easier than moving a few levels higher and selecting the appropriate menu item. But Android error System Recovery 3e "No command" is very rare. It only appears when the user tries to install an update via ADB. This method usually doesn't work. As a result, this error appears. So there is no point in using this method. Nothing will work anyway.

Conclusion

So, let's summarize. We tried to describe Android features System Recovery 3e. The instructions that resulted from this attempt will help novice users of the Android operating system learn how to restore the functionality of their smartphone with their own hands. Which will ultimately lead to broadening your horizons and saving a lot of money.
