3.3 Updating the BIOS
The BIOS (Basic Input and Output System) Setup Utility displays the system’s configuration status and
provides you with options to set system parameters. The parameters are stored in battery-backed-up
CMOS RAM that saves this information when the power is turned off. When the system is turned back
on, the system is configured with the values you stored in CMOS.
The BIOS provides the underlying driver for hardware resources and is the bridge between hardware and
operating system. Now hardware and various applications are constantly updated. When your system
encounters problems, such as the system does not support the latest published CPU, you need to upgrade
your BIOS.
NOTE
：
1. Only upgrade the BIOS if you encounter problems and need to.
2. To upgrade the BIOS, please use the BIOS read/write program attached to our driver CD or download
the updated version of the program from the relevant website.
3. Do not turn off the power or reboot the system during the upgrade process, so your BIOS data will be
damaged and the system may not boot.
4. After the refresh is complete, you need to manually optimize the LOAD Default.
5. To prevent accidents, please backup the current BIOS data first.
