3.2 Introducing BIOS
The BIOS is a program located on a Flash Memory on the motherboard. This program is a bridge
between motherboard and operating system. When you start the computer, the BIOS program gains
control. The BIOS first operates an auto-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. Only when these tasks are completed, the BIOS then transfer the control of the
computer to operating system (OS). Since the BIOS is the only channel for hardware and software to
communicate, it is the key factor for system stability, and in ensuring that your system performance as its
best.
