摘要
在目前日益信息化的社会中,计算机和网络的应用已经全面渗透到日常生活的每个角落。各式各样的新型嵌入式系统在应用数量上已经远远超过通用计算机。任何一个人都可能拥有从大到小的各种使用嵌入式技术的电子产品,小到Mp3,PDA等微型数字化产品,大到网络家电、智能家电、车载电子等设备。在工业和服务领域中,使用嵌入式技术的数字机床、智能工具、机器人、也将逐渐改变传统工业和服务方式。
嵌入式系统可分为有操作系统和无操作系统,然而,在简单的嵌入式系统中,我们往往只需要写一段简单的程序到可编程器件中就能实它的功能。但是,如果当一个嵌入式系统非常复杂的,简单的程序不能满足我们的需求,这时候我们往往会需要功能强大的操作系统支持。但现在几乎所有的操作系统都不能独立的从一块储存介质中启动,例如我们常用的PC机,它也需要BIOS的支持才能完成启动,由此我们想到有没有一种程序可以像BIOS一样引导嵌入式系统启动呢?它的工作原理是什么呢?而Bootloader就为人们实现了这样的功能。

Abstract
In the increasingly information-based society, computer work has been fully rated into every corner of daily life. a variety of new devices in the application of embedded system has been far more than the number of general-puter Any ordinary person may have a variety of large to small electronic products using embedded technology,small devices as mp3, PDA and other miniature digital products, large appliances to work, smart home appliances, car electronics equipment. In the industrial and services sectors, the use of embedded technology as digital machine tools, intelligent tools, industrial robots, service robots will gradually change the traditional way of industry and services.
Embedded system can be divided into operating system with and without operating system, however, in simple embedded system, we just tend to write a simple program to the programmable devices in its functionality can be implemented. However, if and when an embedded system is plex, simple program can not meet our needs, this time we will often need powerful operating system support. But now almost all of the operating system can not separate start from a storage medium, such as mon PC, it also needs bios suppor
