Chapter 3 Introducing BIOS The BIOS is a program located on a Flash Memory on the motherboard. This program is a bridge between motherboard and the operating system. When you start the computer, the BIOS program gain control. The BIOS first operates a self-diagnostic test called POST (Power On Self Test) for all the necessary hardware, it detects the entire hardware device and configures the parameters of the hardware synchronization.
