The BIOS is a program located on a Read Only Memory chip on the
mainboard. This program will not be lost when you turn the computer off. This
program is also referred to as the boot program. It is the only channel for the
hardware circuit to communicate with the operating system. Its main function
is to manage the setup of the mainboard and interface cards parameters,
including simple parameters such as time, date, hard disk drive, as well as
more complex parameters such as hardware synchronization, device
operating mode,
CPU SOFT MENU™ II
techniques, setup of CPU speed.
The computer will operate
normally, or will operate at its best, only if all these parameters are correctly
configured through the BIOS.
Don’t change the parameters inside the BIOS unless you
know what you are doing.
The parameters inside the BIOS are used to setup the hardware
synchronization or the device operating mode. If the parameters are not
correct, they will produce errors, the computer will cra sh, a nd sometimes
you will even not be a ble to boot the computer a fter it ha s cra shed. We
recommend tha t you do not cha nge the pa ra meters inside the BIOS unless
you a re fa milia r with them.
When you start the computer, it is controlled by the BIOS program. The BIOS
first operates an auto-diagnostic for all the necessary hardware, configures
the param eters of the hardware synchronization, and detects all the
hardware. Only when these tasks are completed does it give up control of the
computer to the program of the next level, which is the operating system.
Since the BIOS is the only channel for hardware and software to
communicate, it will be the key factor for system stability, and to ensure that
your system performs at its best. After the BIOS has achieved the auto -
diagnostic and auto-detection operations, it will display the following
message:
PRESS DEL TO ENTER SETUP
Three to five seconds after the message is displayed, if you press the
Del
key, you will access the BIOS Setup menu. At that moment, the BIOS will
display the following message:
