The BIOS will boot as it should. What is BIOS and how to configure it on a standard computer
2015-12-01 | Published in: Bios 38 commentsHi all! In this article I will describe and translate all the important points and sections of the AWARD BIOS. Let's look at the BIOS of this manufacturer using the "Award Modular BIOS v6.00 PG" version as an example.
So, let's begin...
In order to enter the BIOS on your “machine”, you must - after turning on the computer - press the key
Control in the BIOS is carried out by the following keys (I will describe only the main ones):
<>, <↓>, <←>, <→>- moving through points;
- select the desired section/item;
- in the main menu, exit the BIOS, where a notification appears “about accepting and saving the current settings” on or “cancel”. It is also used to exit sections to the main BIOS menu.
<+/PgUp>- change item settings (up);
<-/PgDn>- change item settings (down);
<+>and - work only on Num Lock;
- setting secure BIOS settings;
- installation of optimized BIOS settings;
- save or not save changes in the BIOS (- yes, - no), then exit the BIOS.
And so you entered the BIOS and became familiar with the control keys. Now we will consider all the main sections of this BIOS version. Naturally, let's start with the main menu.
1. Standard CMOS Features
2. Advanced BIOS Features(Advanced BIOS Features)
3. Integrated Peripherals
4. Power Management Setup
5. PnP/PCI Configurations (PNP/PCI service configuration) so this function has lost its relevance in our time, I won’t even consider this small section (setting up interruptions for cards installed in PCI slots) in the options of this section we set Auto.
6. PC Health Status
7. Frequency/Voltage Control (Control of voltages and operating frequencies of devices)
8. Load Fail-Safe Defaults.
9. Load Optimized Defaults optimal settings- Default)
10. Set Supervisor Password
11. Set User Password
And so we figured out the meaning of the sections of the Main Menu - now let's look at all the sections in order and the most basic points that PC users, and in general everyone who is interested in this, would like to know;)
Let's take a closer look at the Standard CMOS Features section
Date and Time set the working date and time using<+>, <>, <↓>, <←>, <→>.
IDE Channel displays a list of connected drives to the IDE controller of the chipset. The picture indicates that two devices are connected: two hard drives indicating their serial numbers and names of drives. And, the numbering of channels and the option for connecting drives are also indicated (Master - main, Slave - slave). I advise you to set the channel detection value to auto.
Drive A and Floppy 3 Mode Support we set the parameters as in the picture None and Disabled (disabled) - a floppy disk drive, which has long been considered an obsolete device.
Halt On- select the option to load the OS when errors are detected during initial testing. Personally, I always set it as in the screenshot - All, Buy Keyboard, i.e. if an error is detected, the system writes it and prompts you to press the key (often F1) to continue loading the OS, you can write down the error, go to the Internet and see how it is resolved - reboot and fix it;) There are also two more worthwhile options at this point
All Errors- your OS will boot if no errors are found.
No Errors- if errors are detected, your OS will still boot.
Extend Memory information about the RAM (Random Access Memory) installed in the system.
Go to the Advanced BIOS Features section
First point in this section Hard Disk Boot Priority(Hard disk boot priority). This item is intended to select from which media the search for the installed OS will begin. If you have two hard drives installed, you should click on this item, then install using the keys<+>, <>, <↓>OS search order on media. Look like in the picture, I naturally set the first one: “Ch0 - primary channel M. - main mode (Master) and after the colon the firm and model of the hard drive ST - seagate380011A” I have the operating system installed on it. You can exit from this point or immediately save and confirm.
Next, an even more interesting section is very important, it’s called First Boot Device (First boot device), in this item we set the type of device from which you want to install the operating system on the PC or already boot from the installed one.
The BIOS offers many settings options, I will describe the most important ones:
CD-ROM(built-in drive) is selected when installing the OS from a bootable laser disk;
USB-FDD And USB-HDD select when installing/booting the OS from a bootable USB flash drive;
USB-CDROM(external drive that connects via USB port).
Also, using simple keys, select the device that suits your case and save the changes. The recommended setup is CD-ROM, but every time you start the computer, the system will search for the OS on the drive, and then only go to the lower (second) level, which is called Second Boot Device.
Second Boot Device(Second boot device) the same setting as in the paragraph above. Recommended Hard Disk setting.
Third Boot Device(The third boot device) can be set to Disabled mode.
Paragraph Password Check is intended for setting passwords (if they are set) not only for entering the BIOS (Setup), but also for entering the OS (Always).
HDD S.M.A.R.T Capability function for monitoring your hard drive (Enabled - on, Disabled - off). In some cases, it may warn you about an imminent hard drive failure, thereby allowing you time to save important information - you should not rely on it;)
Limit CPUID max. to 3 function to recognize your processor, I don’t recommend bothering with it and set it to Disabled.
No-Execute Memory Protect- set Enabled
CPU Thermal Monitor 2 (TM2) monitors the overheating of your processor, a very necessary “trick” is set to Enabled. It can help you if there are problems with the cooling system of your PC.
Init Display First In this section, you are given a choice of which graphics processor will be used to output information to the monitor. If you have a video chipset built-in (integrated) into the motherboard and an external video card connected through a slot on the mat. board AGP (legacy bus) or PCI - Express, then of course in this function we select PCI, otherwise Onboard/PEG.
On-Chip Frame Buffer Size- indicates how much system memory can be allocated for the needs of the built-in video chipset (if there is one), I advise you to set the parameter to 8mb. We're done with this section, let's move on to the next one.
Integrated Peripherals
On-Chip Primary PCI IDE- this option configures the IDE channel (through which, throughout the example, articles are connected to me hard drives), naturally Enabled. If your media is connected via new SATA connectors, then Disabled.
On-Chip Sata Mode - I advise you to set the value as in the picture - auto. The option configures the IDE/SATA chipset controller.
USB Controller- this function is responsible for USB controller Your PC is, of course, Enabled.
USB 2.0 Controller- this function is responsible for the exchange speed through USB ports, of course Enabled.
USB Keyboard Support- the option is responsible for supporting USB keyboards at the BIOS level, turn it off.
USB Mouse Support- the option is responsible for USB mouse support at the BIOS level, turn it off.
Legacy USB storage detect- the option is responsible for identifying and supporting devices connected to USB port, at the BIOS level, turn it on.
Azalia Codec- set auto, thereby enabling the built-in software. sound subsystem board.
Onboard H/W LAN- integrated control option network device- Enabled.
Onboard LAN Boot ROM- option to implement installation via the OS network using an integrated network controller, turn off.
Onboard Serial Port 1- COM 1 port option, set to auto.
Onboard Parallel Port- option LPT port, if the port is not in use (very likely) - Disabled.
Power Management Setup
ACPI Suspended Type- options S1 (POS) and S3 (STR), the option allows you to configure which energy saving mode to use. We choose S3 (STR) - it is more economical.
Soft-Off by PWR-BTTN- Instant - Off and Delay 4 Sec. options, option to configure the power button on the front panel of the PC. The first option (Instant - Off) - instant shutdown, the second option (Delay 4 Sec.) - you need to hold the POWER button for 4 seconds, you choose.
PME Event Wake Up- disable the option.
Power On by Ring- disable the option.
Resume by Alarm- “alarm clock” mode :) You can set the time when your PC turns on - it’s better to turn it off.
Power On By Mouse- turn on the PC using a mouse click, turn it off.
Power On By Keyboard- turn on the PC by pressing a key.
AC Back Function- determines whether the computer should automatically boot after a power failure. Set Soft-Off for home computer there's no point.
PC Health Status - section for automatic monitoring of system cooling
Reset Case Open Status(resetting the case intrusion sensor) - set to Disabled
Case Opened- Yes (the case was opened)
Voltage parameters.
Current CPU Temperature 64 C- the current temperature of your “stone” - the processor.
Current CPU FAN Speed 2626 RPM- rotation speed of the cooler that cools the processor.
Current SYSTEM FAN Speed 0 RPM- the rotation speed of the cooler that cools the mother is 0 in my example, because This fan is not installed.
CPU Warning Temperature- setting the critical temperature of your “stone”, upon reaching which it will give a signal. For different processors, set their critical temperatures accordingly.
CPU FAN Fail Warning- the option allows you to monitor the rotation speed of the processor cooling fan, set it to Enabled. If your cooler stops working, before loading the OS, the system will report an error like "CPU FAN Error", which allows you to take measures to avoid going to the store;)
SYSTEM FAN Fail Warning- the option is similar to the one I described above, only it applies to the fan that blows on the motherboard, it will also give an error before loading the OS. If such a cooler is not installed, turn off the option - Disabled.
CPU Smart FAN Control- a smart option that allows you to automatically adjust the rotation speed of the processor cooler depending on the load, less noise when the PC is idle - Enabled.
Frequency/Voltag Control (Control of voltages and operating frequencies of devices)
I suggest and advise you not to mess with these settings and set the parameters so that the system recognizes frequencies and voltages automatically, as is necessary for stable operation of the hardware. See the screenshot, adjust if this is not the case for you.

The article describes in detail the widely used modern versions BIOS, all BIOS settings, how they affect the operation of the computer, recommendations are given on how to change them and optimize the operation of the computer as a whole.
1. What is BIOS?
Basic Input/Output System, or for short BIOS this is the basic input/output system, which is located in a separate chip on the motherboard and is the most important link control between the computer and operating system. The BIOS determines how computer components are configured when it is turned on, how its devices interact with each other, and how data input/output occurs.
Problems that BIOS solves
- Initialization and initial testing of computer hardware (POST testing).
- Setting up and configuring hardware and system resources.
- System resource allocation.
- Identification and configuration of PCI devices.
- Practicing the basic functions of program calls.
- Handling software interrupts from system devices.
- Basic functions of input/output and interaction of devices with each other.
- Managing computer power consumption, turning off, putting into sleep mode, etc.
BIOS settings have a significant impact on the performance of your PC. Motherboards from different manufacturers use different BIOSes, so it is impossible to give any single instructions for their use, especially since as new processors and motherboards BIOS options are becoming more complex, but still, using the example of several models, you can get a general idea of the adjustments.
BIOS versions
BIOS for computers is produced by several large manufacturers. Among them, the most famous is Award Software. Therefore, we will consider some versions from AWARD. I do not set myself the task of considering this issue in detail, but only want to present this section to you in the shortest form, in order to just have a general idea of existing versions BIOS and understand which version you will encounter when entering the settings on your computer. Therefore, I will present all this only in the form of drawings and names for them, starting with older versions. Above is the picture, below is the title:
Joint BIOS from AWARD + PHOENIX. Used on modern motherboards.
There are also BIOS versions from AMI, PHOENIX, INTEL and other manufacturers, but they are not as common as those presented above.
How to find out the BIOS version on Windows XP?
The easiest way: Start → All Programs → Accessories → System Tools → System Information. Or Start → Run and enter msinfo32 in the “Run a program” window and click OK:
In any of the two cases, the following window will open with the data of your computer, where you can see the BIOS version:
The same can be done using programs like Sandra, Everest, etc. And I want to offer you a convenient program siw, which does not require installation, you can download it. It gives the data in a little more detail:
2. How to enter BIOS settings?
Please handle BIOS settings very carefully and thoughtfully. Inappropriate adjustment can render the computer inoperable or damage its individual components.
When you turn on the computer and start loading the operating system, a message appears on the monitor screen for a short time about how you can enter the BIOS settings. The prompt that appears during the POST procedure looks something like this: Press DEL to enter SETUP , but, as a rule, not all users notice this and do not have time to press the desired key, in our case Delete, to enter BIOS Setup. Alternatively, the key that you need to use to enter BIOS Setup can be found in the instructions for the motherboard.
Missed entering settings? No problem! And even if the OS has loaded, it’s okay. If for some reason there are no instructions for the motherboard, and there is no on-screen prompt, reboot and at the very beginning of the boot, when the hardware is being tested, hold or continuously press the Delete key, less often F1 or F2. This must be done before loading the operating system! If you follow the correct procedure, you will soon enter the BIOS Setup program, where the necessary settings are made.
3. Reset settings to default
If you overdid it with the adjustments or incorrectly set some BIOS parameters, getting completely confused in the settings, for example, doing this for the first time, do not despair. You can very easily return all settings to factory settings.
Option #1
Turn off the power to the computer and remove the side cover system unit. On some motherboards, there is a special button for resetting the BIOS, look for it, press it - and that’s it, the BIOS is reset (picture below):
Option No. 2
If there is no reset button, there is a motherboard CMOS jumper for this. It is located near the BIOS battery. We move the jumper to the adjacent pins for a few seconds and return it to its place (picture below).
The BIOS is designed in the form of several programs. The program used to make the settings is called BIOS Setup. It should be noted that by pressing the Dell or F2 keys when booting the computer, we do not enter the BIOS, but only the program for setting it up. These settings are stored separately in a special dynamic memory chip, which is called CMOS memory or simply CMOS:
Option #3
If it is difficult to find the jumper, you can try the reset method by removing the battery for 15-20 seconds. To do this, we look for the battery on the motherboard - it is large and clearly visible. Carefully, holding it so that it does not fall, remove it from the socket by pressing the latch. Through set time Insert the battery into place until the latch clicks. The settings have been reset to default values, that is, to factory settings (picture below).
This small battery, or simply a battery, provides power to the CMOS memory when the computer is turned off, which is usually located nearby. The battery must provide a voltage of 3 volts. And when it sits down, the computer will not be able to boot, one of the messages will appear on the screen: CMOS-chercksum error or Battery Low Level. One of the first signs of a low battery will be an irregular date and time display. To fix this problem, just change the battery on the motherboard:
Option No. 4
In BIOS versions, for example AWARD BIOS 6.0 PG with classic interface(a similar one will be discussed later) in the initial window of the BIOS Setup program there is a separate option Load Fail-Safe Defaults (second from the top right). If you select it, you can restore the default factory settings. BIOS installation. This may be required if your EXPERIENCES with BIOS have led to unstable operation of the computer, and you do not know how to manually fix the error.
Do you have bootable CD-DVD disc and you want to install an operating system on your computer, in order to do this you will need tune accordingly BIOS and boot from disk. We can also use the device selection in the boot menu, but this function is not always present, for example. on old motherboards. Neither is there any universal button to login BIOS or boot menu. Many motherboard manufacturers assign different keys.
The surest way to identify such keys is to read the documentation for this laptop or computer, but no matter what key it is, you must always press it at the very beginning of loading. As soon as you turn on your computer, the program located in the BIOS automatically starts. BOOT-ROUTINE, which in turn calls the subroutine POST(English) Power-On Self Test), it checks the processor, random access memory (RAM), hard drive (HDD), motherboard elements and other main peripherals. One short the signal indicates that such a self-test completed successfully. This is what the passage might look like POST:
The most common key to enter the BIOS is DEL, we will give other options below. On the screen you see the following invitation: " Press DEL to run Setup", i.e. press the key DEL to log in BIOS. Also during the passage POST A graphical splash screen may be displayed that indicates the name of the computer or motherboard manufacturer.
List of the most common keys to enter the boot menu:
Acer- Esc or F12 or F9; Asrock- F11; Asus- Esc or F8; Compaq- Esc or F9; Dell- F12; ECS - F11; Fujitsu Siemens - F12; Gigabyte- F12; HP- Esc or F9; Intel- F10; Lenovo- F12; MSI(Micro-Star) - F11; Packard Bell- F8; Samsung- Esc; Sony Vaio- F11; Toshiba- F12
The menu for selecting boot devices looks something like this:
You just need to select the desired device from the list and click Enter.
List of the most common keys to enter BIOS Setup : ABIT-Del; Acer(Aspire, Altos, Extensa, Ferrari, Power, Veriton, TravelMate) - F2 or Del; Acer(old models) - F1 or Ctrl+Alt+Esc; ASRock- F2 or Del; ASUS-Del; BIOSTAR-Del; Chaintech-Del; Compaq(Deskpro, Portable, Presario, Prolinea, Systempro) - F10; Compaq(old models) - F1, F2, F10 or Del; Dell(Dimension, Inspiron, Latitude, OptiPlex, Precision, Vostro, XPS) - F2; Dell(old models) - Ctrl+Alt+, or Fn+Esc, or Fn+F1, or Del, or Reset twice; ECS (Elitegroup)- Del or F1; eMachines(eMonster, eTower, eOne, S-Series, T-Series) - Tab or Del; eMachines(some older models) - F2; Foxconn-Del; Fujitsu(Amilo, DeskPower, Esprimo, LifeBook, Tablet) - F2; GIGABYTE-Del; Hewlett-Parkard(HP Alternative, Tablet PC) - F2 or Esc, or F10, or F12; Hewlett-Parkard(OmniBook, Pavilion, Tablet, TouchSmart, Vectra) - F1; Intel- F2; Lenovo(3000 Series, IdeaPad, ThinkCentre, ThinkPad, ThinkStation) - F1 or F2; Lenovo(old models) - Ctrl+Alt+F3, Ctrl+Alt+Ins or Fn+F1; MSI(Micro-Star) - Del; Pegatron- F2, F10 or Del; Samsung- F2; Sony(VAIO, PCG-Series, VGN-Series) - F1, F2 or F3; Toshiba(Portege, Satellite, Tecra) - F1 or Esc.
AMI BIOS - changing device boot priority.
When changing settings and navigating the BIOS menu, use the Enter, +/-, and arrow keys on your keyboard. Use the arrows to move to the tab Boot and select Boot Device Priority:
Here we will see boot sequence: floppy drive first ( Floppy Drive), then hard drive ( Hard Drive), and the third device is turned off ( Disabled). If you want to boot from a disk, then you need the first device in this list to be a CD-DVD drive. Use the arrows to switch to the first device ( 1st Boot Device), press the key Enter and select from the menu that appears CDROM. Booting from a flash drive is done in the same way.
To exit the BIOS while saving the settings you made ( Save and Exit), press the key F10 and confirm ( Ok) key Enter.
Phoenix-Award BIOS - changing device boot priority
Select from the menu Advanced BIOS Features and enter ( Enter).
Here, if we want to boot from the drive, we need to make sure that this device came first on the list. Use the arrows to switch to the first boot device ( First Boot Device) and change to CDROM. Then exit, saving the settings you made ( Save and Exit), by pressing F10.
Error sounds when passing Post
During the initial self-test of the system (pass Post) errors may occur. If they are not critical, then after a certain message is displayed, the computer will continue to boot. If serious errors are detected, the computer system will try to inform the user about them, but often it is impossible to display such information on the screen.
In this case, you will need to be guided sound signals(they are supplied by the system speaker, speaker, upon completion of the procedure Post). Using them, the system reports the results of self-testing. Below is list of such signals For different versions BIOS ( BIOS). Therefore, if your computer beeps, then you can easily determine if your PC is faulty.

Many people consider the BIOS to be a separate chip on the motherboard. In fact, the basic I/O system is firmware set, recorded on a read-only memory (ROM). This is what is often called the “BIOS”.
When the computer is turned on, the programs contained in the ROM provide the ability to operate and initial setup all computer components. They ask parameters and transmit the appropriate commands to the controllers to control the components. Some computer parts have their own BIOS, and communication with them is provided through similar system on the motherboard. Therefore, interaction with hard drive, Flash drive or sdd is possible even before the operating system (OS) starts.
To briefly summarize, the basic system does the following: functions:
- Assessing the performance of equipment at the moment the power is turned on;
- Configuring basic equipment parameters by the user;
- The primary drivers for device operation are also included in the BIOS; the OS uses them until it is fully loaded.
During preboot, information about the state of the computer can be assessed by . Errors downloads are indicated by different signals.
Basic I/O system settings
To access the BIOS setup menu, you must hold down the corresponding key when booting the computer. It depends on the computer manufacturer, but more often Del, F2, F8 or F10. In this case, further loading of the OS stops, and the user sees in front of him basic interface for setup or information.
To enter the interface on ASUS products used F2 key, which is held down before pressing the power button. When working with Windows 10, it is possible to call the interface basic system before rebooting the OS. Shift+item "" in the shutdown menu. In the OS service menu, you need to select “return to factory settings and additional”, then additional options and “start interface UEFI after reboot."
Navigation in BIOS setup mode is carried out using the keys shooter, item selection Enter, and the change in value is +/-. When pressed F1 help appears F9 returns the original settings, and F10 causes exit from the interface while saving the settings. To exit without saving the settings, press Esc.
Main menu
This screen appears after entering the BIOS settings and contains basic information about the computer and the underlying system. Only system parameters can be changed on it. time And date (System time And system date), these items are highlighted in blue. They are given in following format: day of the week<month><number><year> and system time<watch><minutes><seconds>. Information about the hardware is available in the hardware information points. processor manufacturer, its name and clock frequency in GHz (item Processor Information). The size of the installed RAM in MB is also indicated.
In addition, for the convenience of the user, on the right side of the screen in two windows it is indicated, in the top, brief information about the item where the cursor is placed, and at the bottom there is a reminder about the control keys.
Consistently on the main screen the following information about manufacturers and versions is indicated:
- BIOS manufacturer. Paragraph Bios Vendor.
- Base system version, or Version.
- GOP Version. Version of the primary graphics controller (GOP). It helps to identify a discrete video card and provides basic firmware for working with it from the motherboard.
- Primary controller version ( EC Version). It performs the simplest actions when starting a personal computer;
- Operating system serial number or Serial Number. It is required to use the licensed version on this computer;
- User interface access level ( Access Level). Without changing the security settings, the administrator is usually designated here.
The information provided here is of no use to most users. But when upgrading a computer without replacing the motherboard, it becomes necessary. From it you can find out about compatibility equipment with new components. If the new video card refuses to work, there is a possibility BIOS updates to a version that supports the new hardware.
When resetting the settings, the system time is also reset; while on this screen, you need to set the current date and time.
Advanced settings
A menu section that allows you to fine-tune the basic system. It includes a fairly large number of subparagraphs, which vary from version to version:
- Easy Flash. Starting the update from the Flash drive. A useful sub-item that launches the BIOS update procedure directly from a file on the computer’s HDD
- To turn on/off the sensor on the touchpad there is a line Internal Pointing Device. If you set the value to Disable, working with a laptop without a separate mouse will become impossible.
- The line is responsible for activating the laptop when the lid is lifted Wake On Lead Open. When you turn it off, you will have to constantly press the power key.
- To save battery charge when turned off, point Power Off Energy Saving must be enabled. It is responsible for supplying electricity to the USB ports when turned off, which can lead to battery drain.
- Intel Virtualization Technology This is not a very ordinary sub-item; it is related to the ability to process graphic information by the processor when creating a virtual machine in the operating system. For ordinary users disabling or enabling this feature will not change anything
- Data protection when working with the processor is possible when the Intel AES-NI. It is a set of encryption instructions that helps the processor protect data while it is at rest or in transit over a network.
- VT-d or Virtualization technology for directed I/O This item is responsible for using hardware virtualization technology for I/O devices. Now all modern processors support this function; it allows you to process calculations and information from input/output devices virtual machines using the hardware of a real computer on which emulation occurs.
- SATA Configuration. This sub-item contains information about connected SATA devices, such as hard drive and drive optical disks. If you have problems with this equipment, you can get the information you need here.
- Graphics Configuration contains settings for internal GPU Intel. Here you can change the amount of RAM that is allocated for the needs of computing graphic information. The point is responsible for this DVMT Pre-Allocated, it can take values from 64 MB to 512 MB.
- Technology Anti-Theft from Intel allows you to protect your laptop from theft at the hardware level and make data on your hard drive inaccessible if it is especially important. To do this, the computer must have a 3g module. Enabling this feature is located in the Intel(R) Anti-Theft Technology configuration submenu.
- The corresponding submenu ( USB Configuration). When using a keyboard connected to this port, you must be careful about USB Legacy Support. If it is disabled, the keyboard will not work until the OS boots, which means the user will not be able to manage boot disks and flash drives or get into the BIOS interface. Changing an item XHCI will result in termination of support USB devices 0 or USB 3.0. The Auto value allows the base system to work with both versions of the interface.
- Network Stack allows you to boot the OS using virtual disk By local network, even if the computer does not have its own HDD.
Boot menu
In it the user sets order loading information from external storage devices. Here you can also select priority loading of the operating system if there are two or more systems on the computer. Until recently, this item contained only permission to boot from a disk or flash drive and a submenu for priority loading of systems. The last two points were responsible for adding to the boot scheme additional devices and removing unnecessary ones.
With the gradual transition after the release of Windows 8 and 10 to UEFI, an additional item appears called Secure Boot, which prevents you from downloading software from unknown sources. This can make it very difficult to start the OS from a bootable USB flash drive or boot disk, even if they are fully functional. Therefore, when reinstalling the system, you should disable this item.
The function helps the system boot quickly Fast Boot, which is usually always on. The sub-item is responsible for activating the compatibility mode Launch CSM, it is necessary for those users who want to reinstall the OS, possibly even a previous version.
Security
Security allows you to set passwords of various levels when loading the basic system, after it boots, and when accessing the HDD.
The first sub-item is responsible for installation login password into the BIOS setup interface, and it is possible to divide visitors into administrators and users. The administrator has the rights to change all system settings, while the user has severely limited rights.
The following lines are responsible for setting passwords: Set Administrator Password And Set User Password. After their installation, the corresponding items change Status. For the password to HDD principle similar: strings Set Master Password And Set User Password set passwords, the Status line indicates their availability.
Menu for exiting the interface (Save & Exit)
When finishing working with the basic system setup interface or receiving all the necessary information, the user goes to this sub-item.
- Exit without saving settings ( Discard Changes and exit);
- Return to original or factory settings ( Restore Defaults);
- Exit saving all changes ( Save Changes and Exit);
- Save changes made during the last session( Save Changes);
- Delete changes ( Discard Changes).
Paragraph Boot Override allows you to manually select the boot OS in cases where there is more than one on one hard drive.
Launch EFI shell from file allows you to load the OS onto your hard drive from external devices. In this case, you must use the EFI shell, which must be located on removable media.
Troubleshooting BIOS
Most users cannot harm the underlying system through their actions. The first problems begin when you try to improve your computer or laptop.
When increasing the amount of RAM or installing a new video card, it is advisable update BIOS right up to new version. This will help avoid hardware incompatibility. Usually in this case the computer simply refuses to see the new device. After successfully flashing the ROM, this problem disappears.
To initialize this procedure, you must use either internal routines such as Easy Flash, or programs in the OS. You need to find a more modern one on the computer manufacturer's website. It is also advisable to check whether it will support the installed hardware by reading the version description.
Updating the base system version may result in incompatibility with existing installed equipment, since the ROM has a limited volume and support for new devices is possible only by removing information about outdated ones from it. For this reason BIOS update shown only in the case of installing new equipment, and if the computer is operating stably and there are no changes, “preventive” reprogramming is not advisable.
During the rewrite procedure shouldn't happen disconnecting the computer from the network. If this happened, data recovery in ROM will be very difficult, most likely impossible, and then the help of a specialist will be needed. Work on changing the motherboard software is a repair, so the user carries it out at his own peril and risk, losing the warranty if done incorrectly.
When installing password in the basic system and the impossibility of configuring it to restore the computer’s functionality, the possibility was deliberately left hard reset
to factory settings. This feature is related to the peculiarities of storing BIOS settings. The system itself is written to ROM, and its settings are located in another memory called CMOS. To clean it you need to find jumper or jumper near the system power battery (for running the clock when the computer is turned off). Also helps extraction this battery, if it is removable.
Some motherboards allow you to adjust the noise made by the cooler thanks to regulation fan speed. This is useful when using a PC in an office where the noise level is quite high, and the tasks performed by the computer will not cause the processor to overheat.
For lovers acceleration system components, working with BIOS/UEFI parameters becomes a routine task. In advanced versions, you can configure subtle voltage and frequency parameters directly through the interface of the basic system. It is assumed that the user is aware of the consequences of tampering with these parameters. Typically these settings are available for expensive models processors, motherboards and video cards.
On sale SSD drives did not solve the problem of working with huge volumes of data that need to be quickly read from hard drives. In this case, technology is used. To do this, two or more disks are combined, and information is distributed among them according to special algorithms. This way you can get a significant increase in speed and reading information. Most of the configuration takes place in the BIOS interface.
BIOS Setup Utility screens and descriptions are for reference only and may not correspond to what you see on your computer screen - based on a 2005 Intel i915PL chipset based motherboard for Intel (Socket 775) processors.
Main Menu - Main menu.
To allow the user to change basic settings for system and hardware parameters, the BIOS ROM has a built-in BIOS program Setup. The information is stored in battery-backed CMOS memory, and is thus retained when the main power is removed. In general, the information stored in CMOS RAM will not change unless something changes to the system, such as replacing a hard drive or adding a new device.
In some cases, the CMOS battery may fail, causing all CMOS information to be reset. If this happens, you will need to replace the CMOS battery and reconfigure the BIOS.
To enter the setup programs (SetupPprogram):
After turning on the computer, hold down the during self-test (POST). The BIOS setup utility CMOS SETUP UTILITY will open (Figure 1).
