The BIOS essentially starts running as soon as you boot a computer. In fact, the device wouldn’t work without it. This important system ensures that other software on a computer can be loaded. It solves an interesting problem: for the computer to start a software programme, another software programme has to tell it to launch the software. The BIOS is located on a storage module independent from the power supply and therefore runs immediately after switching the computer on. It provides instructions to launch theentire system.
Ideally, you should never have to access the BIOS. That’s why entering the programme is not very intuitive. BIOS is only intended to start the actual operating system and all the necessary components. Computer manufacturers therefore only allow the BIOS to be launched for a few seconds when booting the system. When the computer boots, a screen message will indicate a certain key that has to be pressed to open BIOS. You will usually have just enough time to do so before the start screen of the operating system appears.
