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 humancomputer 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.
Setting the parameters of the BIOS correctly could enable the system operating stably
and reliably; it could also improve the overall performance of the system at the same
time. Inadequate even incorrect BIOS parameter setting will decrease the system
operating capability and make the system unstable or even unable to operate normally.
BIOS Parameter Setup
Prompt message for BIOS setting may appear once the system is powered on. At that
time (invalid at other time), press the key specified in the prompt message (usually
<Del>) to enter BIOS setting.
When the BIOS setting in CMOS is destroyed, system may also require entering BIOS
setting or selecting certain default value.
All the setup values modified by BIOS are saved in the CMOS storage in system. The
CMOS storage is powered by battery; unless clearing CMOS is executed, its contents
would not be lost even if powered off.
Note!
BIOS setting will influence the computer performance directly. Setting
parameter improperly will cause damage to the computer; it may even be unable to
power on. Please use the internal default value of BIOS to restore the system.
Our company is constantly researching and updating BIOS, its setup interface may
be a bit different. The figure below is for reference only; it may be different from
your BIOS setting in use.
