CMOS Memory

Author: Date: 1996-10-25

        Your computer alsouses some nonvolatile RAM(NVRAM),also called complementarry metal-oxide semiconductor (CMOS) memory,on the system board for storing configuration and setup information. Powered by a small battery, CMOS retains its contents while computer power is off. CMOS maintains information about:
        ○ Date and time
        ○ Security features
        ○ Power management settings
        ○ Storage devices
        ○ Keyboard and mouse
        ○ Port assignments
        ○ I/O addresses and interrupts
        ○ Video settings
        ○ Other selectable features

        CMOS存储器

        计算机在系统板上也使用一些非挥发性随机读写存储器(NVRAM)又称为互补金属氧化物半导体(CMOS)存储器来储存配置和设置信息。CMOS由一个小电池供电，当计算机掉电时继续保留其内容。CMOS保存以下信息：
        ·日期和时间
        ·安全特性
        ·能源管理设置
        ·存储设备
        ·键盘和鼠标
        ·端口分配
        ·I/O地址和中断
        ·视频设置
        ·其它可选特性
