21 第三章 BIOS 功能简介 第三章 BIOS 功能简介简介 BIOS(Basic Input and Output System: 基本输入输出系统 ) 固化在 CPU 板上的闪存存储器中, 主要功能包括 : 初始化系统硬件, 设置各系统部件的工作状态, 调整各系统部件的工作参数, 诊断系统各部件的功能并报告故障, 给上层软件系统提供硬件操作控制接口, 引导操作系统等 BIOS 提供用户一个菜单式的人机接口, 方便用户配置各系统参数设置, 控制电源管理模式, 调整系统设备的资源分配等等 正确设置 BIOS 各项参数, 可使系统稳定可靠地工作, 同时也能提升系统的整体性能 不适当的甚至错误的 BIOS 参数设置, 则会使系统工作性能大为降低, 使系统工作不稳定, 甚至无法正常工作 BIOS 参数设置每当系统接通电源, 正常开机后, 便可看见进入 BIOS 设置程序提示的信息 此时 ( 其它时间无效 ), 按下提示信息所指定的按键 ( 通常为 <Del> 键 ) 即可进入 BIOS 设置程序 CMOS 中 BIOS 设置内容被破坏时, 系统也会要求进入 BIOS 设置或选择某种默认设置值 通过 BIOS 修改的所有设置值都保存在系统的 CMOS 存储器中, 该 CMOS 存储器由电池供电, 即使切断外部电源, 其内容也不会丢失, 除非执行清除 CMOS 内容的操作 注意!BIOS 的设置直接影响到电脑的性能, 设置错误的参数将造成电脑的损坏, 甚至不能开机, 请清 CMOS 后再使用 BIOS 内置缺省值来恢复系统正常运行 由于本公司不断研发更新 BIOS, 其设置界面也会略有不同, 以下的画面供您参考, 有可能跟您目前所使用的 BIOS 设置程序不完全相同 CLDNA(B)

61 Chapter 3 BIOS Setup Chapter 3 BIOS Setup 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. 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 operating unstably even unable to operate normally. BIOS Parameter Setup Prompt message for BIOS setting may appear once powering on the system. At that time (inefficient 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 contents, or else its contents will not be lost even if powered off. Note! BIOS setting will influent the computer performance directly. Setting parameter improperly will cause damage to the computer; it may even 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 CLDNA(B)
