Important Information


  • BIOS, abbreviation of Basic Input/Output System, is integrated in ROM chip on main board, which contains the basic input/output program, system configuration information, system startup self-check and pre-setup programs. BIOS provides most basic low-level hardware operations; it is the connection between software and hardware, and interfacing window of hardware and operating system.

    Note: Make note of any settings you have changed in the BIOS Configuration Utility. These settings may have to be re-entered after updating the BIOS.

    Attention: Do not power off or restart your computer during the BIOS flashing process, which will cause serious damage and improper functioning of your computer.
