        计算机把各种系统程序和数据存储在闪烁存储器中，以便在机器升级时可以更新它们。存储在闪烁存储器中的有：
        ·基本输入输出系统(BIOS)
        ·上电自检程序(POST)
        ·配置/设置实用程序
        ·必要的产品数据(VPD)
        ·即插即用配置信息
        ·ISA传统配置信息
        Flash Memory
        To store programs for startup procedures and other internal operations,your computer uses read-only memory (ROM). These programs are encoded in ROM modules on the system board. ROM is nonvolatile memory, which means that it retains its contents when the computer is turned off. Generally, the contents of a ROM module cannot be modified. However,electrically erasable programmable ROM (EEPROM) modules (also referred to as flash memory), can be reprogrammed while they are in the computer.
        Your computer stores various system programs and data in flash memory so that they can be updated whenever enhancements are made. Stored in flash memory are:
        o Basic Input Output System (BIOS)
        o Power-on self-test (POST)
        o Configuration/Setup Utility
        o Vital product data (VPD)
        o Plug and play configuration information
        o ISA legacy configuration information
