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 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.
