No, even the most simple, computer technology is not without basic input-output.She, like many others in the computer field, received a Russian acronym based on the English names.In addition, part of the word means a system used in the masculine gender.The word "BIOS" is derived from the Basic Input / Output System (BIOS).Physically presented chip on the motherboard, which is recorded in a block of specialized firmware.
When you turn on the computer program control is transferred to the BIOS, that perform basic tests of all major constituents prescribe devices free the IRQ and configure all hardware components.After all tasks are polled disk drives and download.
Remove the system unit or a single video card memory module and turn on the computer: a loud speaker squeak usher in problems with the equipment.This is one of the results of the test firmware if no video card, then you can not work, obviously, etc.In addition, the BIOS provides the operating system access to the complete set.It should be noted that with the improvement of operating systems an opportunity to transfer to them a part of the BIOS functions.In particular, the hardware configuration can be executed not only the BIOS, but the system.The user can make adjustments to the work of most of the stages of the base system.Currently, the classic BIOS is gradually beginning to replace his successor - UEFI (Unified Extensible Firmware Interface).If the BIOS has a simple graphical interface, which is supported by the mouse, it is UEFI (at least for now, the situation is).It is not surprising that many people want to learn how to start the BIOS.The study of computer training books begins with this.
Frankly, without the knowledge of how to run the BIOS, complete the work with a computer will fail.Before installing the operating system, you need to configure the BIOS.In personal computers for many years there is a standard to access the settings.You do not know how?Run the BIOS can be as follows: immediately after the often should press the «Del».Although the fact of pressing the buttons is polled at a certain point, it is sometimes possible to lose so often push immediately, without waiting for clues.
Going into the BIOS setup, you can select the mode of operation of ports USB, overclock the processor and memory, adjust the boot sequence from different devices to tell the system how to initialize the hard disk controller (SATA mode or compatible with IDE).This is only a small part of all possibilities, so know how to start the BIOS, is necessary.
Unlike personal computers, including notebook manufacturers, alas, there is no standardization, allows you to quickly find out how to start the BIOS.That is the usual pressing buttons «Del» nothing.Why is it done, history is silent, but the additional headache to owners of mobile computers provided.
In this case, it is recommended to read carefully the messages displayed on the screen before booting the system.Often, there is indicated the desired button.You can also try to press Esc (Toshiba laptops), F2 (common), F3 (Dell and Sony), F10 (Compaq), and, of course, Del (Acer).
The forums often asked the question, "how to set the BIOS?".It is not entirely correct, though understandable.In this case we are talking about upgrading the existing BIOS.After the release of the motherboard or laptop with certain versions of the BIOS for sale to users who purchased the product, for quite some time (sometimes several years) is available from the developer the ability to download an updated version of the firmware and replace its existing one.New versions can add missing features settings, to improve compatibility with the equipment to work correctly and so forth. The site is always is a list of the changes - to him be sure to familiarize yourself before to flash (update) the BIOS.The program to upgrade and instructions for its use is usually given along with the update file.
