Chapter 3 BIOS Setup
BIOS Overview
BIOS (Basic Input and Output System) is solidified in the flash memory on the CPU
board. Its main functions include: initialize system hardware, set the operating status
of the system components, adjust the operating parameters of the system components,
diagnose the functions of the system components and report failures, provide hardware
operating and controlling interface for the upper level software system, guide
operating system and so on. BIOS provides users with a human-computer interface in
menu style to facilitate the configuration of system parameters for users, control power
management mode and adjust the resource distribution of system device, etc.
Correct BIOS settings make system more stable and reliable and also improve the
overall performance of the system. Inappropriate or wrong BIOS settings reduce the
performance of system, make system unstable and even unable to work normally.
BIOS Parameter Setup
Prompt message for BIOS setting may appear once the system is powered on and the
computer booted. At that time (invalid at other time), press the key specified in the
prompt message (usually <Del>) to enter into BIOS setting.
If the BIOS setting in CMOS is destroyed, system will ask you to enter BIOS setting
or select certain default value.
All the setup values modified by BIOS are saved in the CMOS storage of the system.
The CMOS storage is powered by battery; unless clearing CMOS is executed, the
settings would not be lost even when the power supply is cut off.
Note!
BIOS setting will influence the computer performance directly. Wrong
settings may damage computer or even prevent boot up. After clearing CMOS, use
the internal default value of BIOS to restore the normal operation of system.
Our company is constantly researching and updating BIOS, so the setup interface
may be a bit different. The figure below is for reference only; it may be different
from your BIOS setting procedure in use.
