Surely almost every userfaced with the acronym BIOS (well-established designation in the Russian-speaking computer world - BIOS). But here's what it is, how to properly configure the BIOS, and what functions this system performs, not everyone knows. Let's try to deal with basic concepts and settings.
What is BIOS?
In general, the term BIOS itself, if translatedabbreviation from English to Russian, means basic input / output system, but not in understanding such actions with information as such. The BIOS serves as an interlayer for the interaction of system and application programs with computer hardware.
If you understand, Windows can also be attributed tocomplex program (set of programs) that communicates between the computer and the user. But now, in order for these programs to work, we need not only device drivers, but also a BIOS system, which allows even before starting the OS to initialize absolutely all the iron components and to reconcile their parameters with the requirements of correct operation of the "OS".
Preliminary acquaintance to functions
Talking about how to properly configure the BIOS oncomputer or laptop, it is impossible not to address the issue of basic functions. In addition to the above, you should pay attention to low-level testing of equipment before starting the system. If no problems are found, the management of the iron components is transferred to the "OS".
Otherwise, the screen is issuedrelevant notice. But many, probably, faced with such situations. For example, on a computer, for some reason, the keyboard was turned off. Immediately there is a message about its absence. Or, say, a hard disk crash occurred, to which the BIOS responds instantly.
Equally important is the save function.device parameters, that is, the characteristics of the hardware of a computer or laptop, despite the fact that its own BIOS memory is only about 1 MB. But such data is not stored on the hard drive, but in a special chip located on the motherboard. By the way, a person familiar with the settings in BIOS Setup mode can easily optimize the performance of any component, although, as practice shows, ordinary users hardly resort to such procedures.
The most necessary parameters for computers and laptops
How to properly configure the BIOS on a laptop or computer in terms of basic parameters?
When entering the settings is most often used.long press of the Del, F2, F10 or F12 keys (here everything will depend on the BIOS manufacturer and its current version). In any case, the main settings window on almost all devices looks identical. The difference can only be in the names of categories and menus (for example, Boot Sequence and Boot Priority, meaning the priority and boot sequence from a specific device, which is set first, second, etc. in the queue).
The first thing you should pay attention to when enteringIn the main window, this is the setting of the system date and time. Remember, this installation is done here, and not in the standard Windows settings. Many users who do not know about this can often have problems installing software, because the installer is initially focused on the parameters set in the BIOS, and not in Windows. It turns out that even with one date, which was set in the system, the main one (in BIOS) is excellent, therefore a conflict arises.
How to properly configure the BIOS to install "Windows" from the disk?
Теперь коснемся не менее важного вопроса, associated with the initial installation of "OSes" from the disk. How to properly configure the BIOS in this case? The main point is to set the above boot priority.
In other words, the user is required tothe launch process was not from a hard disk, but from removable CD / DVD media. In most cases, this is done from the boot section, where the optical drive must be specified as the first device (1-st Boot Device). You can change the boot device using the standard PgUp and PgDn keys that are available on any keyboard. Next, you need to save the changes (usually the F10 key or the Save & Exit command), followed by an automatic restart, and the start will be made from the optical disc.
Setting up the BIOS for the installation of "Windows" from the flash drive
Now a few words about how toconfigure the BIOS if the system installation will be made from a removable USB-drive. Such situations are most common when the netbook drive is simply not provided.
In principle, the question here also comes down toto install a priority device, but only it will not be a disk, but a flash drive. Please note that the flash drive must be inserted into the appropriate USB port even before turning on the computer or laptop, otherwise it will not be detected.
How to properly configure the BIOS ("Windows 7") after installing the system
Upon completion of the initial installation phase of the sameWindows 7, however, like any other system of this family, always restarts the terminal. If you do not change the parameters of the priority device, the user will only face the fact that the installation will be restarted.
The conclusion is the simplest:When rebooting, enter the settings and set the hard drive as the main (first) device. In principle, if the drive is the first and the hard drive is the second, simply pull the installation disk out of the drive. But it is better to change the settings immediately. Suddenly you will play a game that requires the presence of the original disc, forget to remove it and turn off the computer! When turned on, a message will be shown that this disk is not a system drive, and the settings will have to be changed again.
Next, pay attention to the question of how toconfigure BIOS on some models of laptops from different manufacturers. Basically, the setup is almost the same, but there are some points that are worth staying separately.
Setting up the BIOS in laptops ASUS
So, how to properly configure the BIOS on a laptopASUS in terms of boot priority? First, we enter the program by pressing F2 or Del, then go to the Security section, find the Secure Boot Menu section and disable the Secure Boot Control option (set it to Disabled).
Go back to the Boot section and useLaunch CSM appeared. Save the changes, reboot the laptop and go to the BIOS again. Now in the Boot section as a priority device, you can install a floppy drive or flash drive. The question of how to properly configure the BIOS (ASUS), should not cause special difficulties. By the way, such settings are enabled by default on almost all devices from this manufacturer.
BIOS setup in Acer laptops
Now consider how to properly configure the BIOSon an Acer laptop. In principle, everything looks standard here, but some additional options deserve the main attention. This is the F12 Boot Menu. When this option is enabled, the user will be asked to choose from which device to make it before loading the system, which saves the user from specifying priorities manually.
The second interesting parameter is D2D Recovery, which allows you to activate system recovery. But it is desirable to use it only with the special utility Acer Recovery Management.
Finally, the third parameter Power On Display allows you to control the on and off of the main screen, if an external monitor is connected to the laptop.
BIOS setup in Hewlett Packard laptops
Still it is worth saying a few words about how to properly configure the BIOS on an HP laptop. Here, too, has its own interesting moments.
Immediately after turning on the device, press the Esc key, then the Startup Menu will appear on the screen. What is it interesting? The fact that it has two items: F9 Boot Device Options and F10 BIOS Setup.
The first option is selected for a one-time start withchoosing a device, the second one will enter directly into BIOS settings. Here, in the system configuration section, go to the Boot Options, where you should use Boot Order. Only scrolling up and down is done with the F5 / F6 keys. However, for booting from optical media, it is better to set the priority option directly to the BIOS. The manager must be left to choose the start from the flash drive.
Some features in BIOS setup for abnormal situations
Naturally, these functions and BIOS settings do notare limited. For example, in a situation where there are problems with hard drives, a complete check may be required, which includes surface diagnostics.
No matter which utility will bebe used (Windows own tool or third-party program), it is desirable to perform a full check when changing the SATA controller parameter from AHCI to IDE mode.
Among other things, if anyone knows, BIOSIt also allows you to control some other parameters, say, the temperature of the processor, the rotation speed of the spindle of the hard disk, the memory capacity of the devices. With this program, you can set various parameters of IRQ interrupts, turn on or turn off devices, load the system over the network, etc. Although, if you look at it, an ordinary user practically does not need such settings (unless, with rare exceptions), and without the need for BIOS without special knowledge, as they say, it is better not to climb at all.
Conclusion
That's all for the question, how toconfigure BIOS. As is already clear, specific settings that may be needed in emergency situations were not considered in this material. But here are some interesting parameters that have been affected. However, if someone has a desire to study the BIOS settings, so to speak, in a larger volume, it will not be labor. At the very least, you can read the technical documentation or use the tips, which are usually displayed on the right side of the screen when entering a particular menu. But the settings themselves are almost always automated and set to use the best defaults.
Well, the problem of installing priority devicesfor downloading the date and time, I think, it will not cause any particular difficulties, since the actions are identical even in devices from different manufacturers. Here the most important thing is to find the appropriate section, and to understand the titles you will need minimal knowledge of the English language.
