This information can be useful when there is a problem in turning on the computer. When we start the PC, we can hear several “beeps” which show us how our hardware is.
First we’ll have to identify which type of BIOS we have. We can see that as soon as we turn on the computer, it tells us the type and the version. If we don’t have time to see this, we simply enter in the BIOS configuration and there we can find this information. To enter in this configuration, each manufacturer determines a button with which we can access it. It’s normally ESC, but it can also be F2, F10 and other buttons. We can find this information in the instructions of the base board.
