Also sometimes used reducing translation BSVV.

Regardless of what name is used is a set of firmware that enable a computer, notebook and various connected devices to function.

The BIOS is part of system software. Usually, it means something that is in the motherboard, but the firmware are also present in the peripheral devices. In addition, allocate NetBIOS.

The software starts to function long before the device becomes fully enabled. In General, we can distinguish a number of appointments of the BIOS.

  • He checks the condition of all equipment;
  • Makes loading the operating system;
  • Provides an API that the equipment can work;
  • Produces installation.


Stages of work the BIOS

Almost immediately after pressing the power button of the computer or laptop, the control is passed to the firmware. First, the BIOS:

  • Runs the POST, which stands for power-on self-test. The result is a check of all systems.
  • After that, the program reads settings from a persistent storage device.
  • These settings are then.
  • The next step is to search for and download code OS loader.
  • When this is completed, control is passed directly to the loader.

A huge part of the work of BIOS associated with a variety of devices that are related to the motherboard. On them the program drew attention in POST process. In that case, when the result of checking an error is detected, that is, a failure occurs, the BIOS displays the information about what caused such.

If the software is unable to display the appropriate message, it emits a special beep. Their duration, the tone and style often vary among manufacturers.

When there are no errors, start the operating system. In addition to the master boot record, this process may occur and with flash or regular drive. It is widely used want to change operating system or reinstall Windows. But of course the BIOS is needed not only for this.

The BIOS gives you the opportunity to carry out a number of great settings. In its menu there are various items, here are some of them:

  • Working with date and time on the system clock;
  • The launch of the system for acceleration, or, conversely, to complain;
  • Connect and disconnect equipment connected to the motherboard.
  • The change in the functioning of the POST. The removal of some of the tests enables faster loading, but this can not be seen serious problems;
  • Working with loaders of the operating system that need to reinstall Windows.

Due to the fact that the software can make major changes that can damage the functioning of computer or laptop, the BIOS is equipped with a system rollback. To do a factory reset in several ways. In particular, this is done within the program, or uses a special key combination during the boot process the BIOS.
