Rearrange bios from another planet. Bios settings - Detailed instructions in pictures. Solving problems with a crashed BIOS
If you were looking for BIOS settings in pictures, then you have come to the right address.
The changes made will be protected lithium battery, built into the motherboard and maintaining the required parameters in case of 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 mode of operation hard disk, you need to select a hard disk (for example: "SATA 1", as shown in the picture).
- 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 more fast work here we recommend choosing the AUTO mode;
- 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;
- change clock frequency 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 hard drives several, 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- Sequencing the information screen of the modules connected to motherboard(MT) via 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.
- ASUS EZ Flash- using this option, you have the opportunity to update the BIOS from such drives as: floppy disk, Flash-disk or CD-ROM.
- AI NET- using this option, you can get information about the cable connected to the network controller.
Exit Section - Exit and Save
Special attention should be paid to the EXIT item, which has 4 operating modes:
- Save Changes- we save the changes made;
- Discard Changes + EXIT- we leave the factory settings in effect;
- Setup Defaults- enter the default parameters;
- Discard changes- we cancel all our actions.
The given step by step instructions Explain in detail the purpose of the main BIOS sections and the rules for making changes to improve PC performance.
Bios setup
Bios settings- Detailed instructions in pictures
In this post I will write how to reset (clear) the BIOS. The article is intended for beginners.
So, for some reason, we need to reset (clear) the BIOS. Or, as they sometimes say - to make "clear kmos" (clear_cmos).
To facilitate this operation, some motherboards of the upper and middle price range are provided by the manufacturer with buttons that allow you to almost instantly clear the CMOS data.
They are usually marked with "clr_cmos" (clear_cmos).
They can be located both on the front of the board itself:
So the back of the motherboard can be located:
And sometimes without an inscription at all:
[Instructions on how to clear the BIOS using this "quick reset button" will be at the end of the note].
But on ordinary motherboards (which are ~ 99% of the total) there are no such "conveniences". But there is no reason to be upset - absolutely every motherboard has a three-pin connector. This connector is just intended for cleaning bios (kmos).
They might look like this:
As you can see in all three pictures, a two-pin jumper (or jumper) is installed on the three-pin connector. The jumper can only close two contacts of three. For all motherboards (and hard drives, by the way) these jumpers are absolutely standard - identical, that is.
This is how the jumper (jumper) looks like:
They can be found both on the motherboard itself - in the box or on the motherboard itself, where it is already installed on a three-pin connector in position 1-2 (as you might have noticed in the three pictures above). Here's how in the photo below:
Or find a jumper on hard drives where it is already installed in some position.
But - on modern motherboards manufacturers usually do not install any jumpers. Then you need to look for them in the store where you bought the motherboard - ask for one thing - and you will be given it for free.
In this particular case, we will consider the MSI P67A-C43 motherboard.
It looks like this:
On the modern boards a three-pin connector for cleaning KMOS is marked with the inscription "JBAT1" (presumably - Jumper Battery 1). We are looking for her:
Found her. What need to do?
The instruction is as follows:
1. Turn off your computer in advance.
2. Move the button on the power supply unit (PSU) to the "0" position.
3. Pull the 3-pin power plug out of the PSU's "ass".
4. Wait then for about 15 seconds and then take the jumper and bridge pins 2-3. Photo below:
If the jumper is already in position 1-2, then the jumper should be moved from position 1-2 to position 2-3. Photo below:
5. Wait seconds 5. Then return the jumper back to its original position 1-2. Even if there was no jumper, still let it remain in position 1-2.
This is normal as position 1-2 for the jumper is standard / nominal working.
Never leave the jumper in position 2-3! This is fraught with unpleasant consequences for the performance of the motherboard!
6. After installing the jumper in position 1-2, you can turn on the computer. Bios as they say "virgin clean".
P.S. Now about how to reset the BIOS using the "quick button".
We do the same as above, but instead of "dancing with jumpers" we just press the button.
Most often we remember about BIOS ( Basic System I / O) only when we need to reinstall operating system and you need to set it to boot from a disk or flash drive. I often wrote about this in articles like:, and others. Now I want to put together and refer only to this article when necessary. This article will be useful for all versions of BIOS and for different companies. A kind of unified directory
The first thing you need to know is that BIOS is divided by manufacturer and version.
To change boot method in BIOS- you must first enter it.
You can, of course, find out what version and manufacturer of your BIOS, from the manual that comes with the computer.
You can also find out by looking at the line at the top on the black screen during boot (the manufacturer will be indicated there).
Well, then enter the BIOS, knowing what kind of BIOS you have.
In some versions of the BIOS there is no such screen with displaying lines. There is simply a logo and at the bottom it says something like "Press F2 to enter SETUP" and then press F2. If there is just a logo and there are no inscriptions - press ESC, and then del or f2
Here is a small list of manufacturers and keyboard shortcuts for entering BIOS:
Also, at the bottom of the black screen, keys are written to enter the BIOS and to display a list that contains the available devices for loading and so that you can boot from it. But about him at the end of the article.
As you can see - most often you need to press a key F2 or Del.
Now you need to put a USB flash drive or disk in the boot.
Let's look at a few examples that differ from the BIOS manufacturer.
Setting up Award Bios for booting from a USB flash drive or disk:
The main window looks like this, in which we need the second item:
Further depends on the firmware version. In one case, you will need to go to an item similar to "Boot Seq & Floppy Setup"
otherwise, you don't need to go anywhere - everything will be right before your eyes
Click on First Boot Device(First boot device), click Enter and such a window will appear
in which you need to select the disk or flash drive that will be launched first. You can specify the Second boot device, for example, but usually the BIOS fills in this data itself.
On a note:
If you choose a USB flash drive, then, among other things, you also need to go to the item "Hard Disk Boot Priority "and move our flash drive to the very top using the" + "and" - "or" PageUp "and" PageDown "buttons:
It is also worth remembering that in order for the BIOS to see the USB flash drive, it must be connected before turning on or before rebooting
Then we press "F10" (for the exact key, see the prompt at the bottom of the screen with the name "Save", "Exit") or go to the main BIOS menu and select the item "Save and Exit Setup". In the red window, select "Yes" with the "Y" button on the keyboard and press "Enter"
The computer will reboot and when booting from installation disk with Windows, you may be prompted for a few seconds "Press any key to boot from CD or DVD ..."
Which translates as "Press any button to boot from CD or DVD".
This means that if at this moment you do not press any button on the keyboard, the computer will continue to boot from the next device in the list.
Another kind of this BIOS:
I met this only on old computers ten years ago until 2003. The main menu looks like this:
To customize the boot order, you need to go to the menu BIOS FEATURES SETUP:
At this point, we just select with the PageUp and PageDown buttons (or Enter and arrows) what to put first - CDROM or USB flash drive. Don't forget the second and third device
And further:
How to choose where to boot from in AMI BIOS
If, after entering BIOS, you see such a screen, then you have AMI BIOS:
Use the "right arrow" button on the keyboard to move to the Boot tab:
Go to "Hard Disk Drives" and in the line "1st Drive" (may be called "First Drive") select a disk or flash drive:
Next, go to "Boot Device Priority", go to "1st Boot Device" and select from the list what you have selected in the previous tab (ie if you have selected a USB flash drive in Hard Disk Drives, then you need to specify it here too. This is important! )
To boot from a CD / DVD disk, you need to select "ATAPI CD-ROM" (or simply "CDROM") in this menu, and there is no need to go to the previous menu "Hard Disk Drives".
Now we save the results by pressing "F10" or go to the BIOS section "Exit" and select "Exit Saving Changes".
Another AMI BIOS, but everything is clear here:
Configuring Phoenix-Award Bios to Boot from a USB Flash Drive
If, after entering BIOS, you see such a screen, then you have a Phoenix-Award BIOS:
We go to the “Advanced” tab and opposite the “First Boot Device” set what you need (a USB flash drive or disk):
Save with the F10 key
Configuring EFI (UEFI) Bios with a GUI to boot from a USB flash drive
Now you will not surprise anyone with this. Almost all new computers come with this kind of shell. You can read more about it in the article.
When loading, at the bottom of the screen there is a section "Boot Priority", where you can use the mouse (drag and drop) pictures to set the desired boot order.
You can also click the "Exit / Advanced mode" button in the upper right corner and select Advanced mode in the window that appears.
Next, go to the "Boot" tab and in the section Boot Option Priorities in the "Boot Option # 1" field, set boot device by default USB flash drive, DVD-ROM, HDD or another available device.
How to boot from a USB flash drive or disk without entering BIOS
This is what I wrote about almost at the very beginning of the article.
This is when you need to press a key once and a window with a choice of loading will appear. This method does not change the BIOS settings.
Usually Award BIOS prompts you to press "F9" to call boot menu, and AMI asks to press "F8". On notebooks, this may be the "F12" key.
In general - look at the bottom line and look for items like "Press F8 for BBS POPUP" or "Press F9 to Select Booting Device after POST".
Why can't I boot from a USB flash drive in BIOS?
Possible reasons: 
On ancient computers, there is no way to boot from USB sticks at all. If there is no newer BIOS, then the project can help.
1) Download from the link above latest version"Plop Boot Manager" and unpack it.
2) The archive contains files: plpbt.img - an image for a floppy disk, and plpbt.iso - an image for a CD-ROM.
3) We write the image to disk and boot from it (or from a floppy disk).
4) A menu will appear in which we select our USB flash drive and boot from it already.
Small decoding of drive designations when choosing:
Do not forget after you have done what you wanted (namely, why did you change the boot in the BIOS) - return the boot settings back so that the computer boots from the hard drive.
