work, the BIOS program 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).
