指控系统中多操作系统启动工具的研究

摘要

指控系统中GRUB2作为启动引导器，管理多种操作系统平台。GRUB2采用模块化设计，可以提供给使用者更大的灵活性和性能改进。Linux系统的模块化设计与运行机制已被广泛讨论，有关GRUB2的模块化设计与运行机制的资料却很少。为了了解它的模块化编程与运行机制，通过对一个模块程序的分析，介绍了GRUB2中模块程序的基本结构及模块化设计的灵活性；并讨论了GRUB2的模块运行机制，明确了模块运行所需的底层工作。在此基础上，可以对GRUB2进行二次开发，扩展其应用场合。%As a boot loader,GRUB2 for Command and Control Systems manage a wide range of OS platform. GRUB2 uses a modular design,provided to the user greater flexibility and performance improvements. It is being discussed very clear on Linux module programming and running mechanism, but the same information about GRUB2 is seldom. In order to understand GRUB2’s modular programming and running,by analyzing a module program,its basic structure of module program in the GRUB2 is introduced and the flexibility of GRUB2 modular design is showed,by discussing GRUB2 module mechanism,the underlying work solution that required to run the module is clarified. On this basis,GRUB2 can be redeveloped to consummate its functions and extend its application occasions.
