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 will gain 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 done it gives up 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.
