BIOS Setup
BIOS (Basic Input and Output System) records hardware parameters of the system in the
CMOS on the motherboard. BIOS identifies, configures, tests and connects computer
hardware to the OS immediately after a computer is turned on.
Its major functions include conducting the Power-On Self-Test (POST) during system startup,
saving system parameters and loading the operating system, etc. BIOS includes a BIOS Setup
program that allows the user to modify basic system configuration settings or to activate
certain system features.
When the power is turned off, the battery on the motherboard supplies the necessary
power to the CMOS to keep the configuration values in the CMOS.
Important
• Because BIOS flashing is potentially risky if you do not encounter problems using the
current version of BIOS, it is recommended that you not flash the BIOS. To flash the BIOS, do
it with caution. Inadequate BIOS flashing may result in system malfunction.
BIOS Setup
The default settings offer the optimal performance for system stability in normal conditions.
It is recommended that you not alter the default settings (unless you need to) to prevent
system instability or other unexpected results. Inadequately altering the settings may result
in the system's failure to boot.
Important
• BIOS items are regularly updated for better system performance. The items may be slightly
different from the latest BIOS; therefore, the description is for reference only.
