configurations may lead to difference in BIOS screen and 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.
