引导程序

The circuit diagrams and the definition of hardware interface of each module are given. Thirdly, the bootload is designed according to the address mapping of the PCB and the start-up procedure of ARM processor.

接着，通过对ARM处理器启动流程的研究，并根据电路板的地址映射，详细阐述了系统引导程序的设计思路，并给出了程序流程图。

On the boot disk in the boot sector.

引导程序放在磁盘的引导扇区中。

Xiezhy bootloader is also a very nice booter which looks like boot camp. It has no RAID support but besides that you can try it, you will like it.

Xiezhy引导器也是一个非常好酷似boot camp的引导程序，它不支持RAID，但你也可以试试，你会喜欢它的。

This may be convenient to developers who write installation or bootstrap or initialization programs.

这给安装程序或者引导程序或者初始化程序的开发者带来了方便。

If the disk is infected with the virus, the memory is read the first part of the virus program, it has been modified after the control of the size of memory space available in high-end memory think of a region, and moved to the first part of the area, and then read on the disk "bad cluster" in the second part of the first part and to put together, so that all proceedings on the presence of the virus in memory of the high-end, and then modify the interrupt vector INT13H or other interrupt vector to the high-end virus program, then you can read the original boot memory and the control over to it to complete the system startup.

如果是染上病毒的盘，读到内存的是病毒程序的第一部分，它得到控制权后修改内存可用空间的大小，在内存高端辟出一块区域，并把第一部分移至该区，接着读入放在磁盘"坏簇"中的第二部分，并和第一部分拼起来，使病毒程序全部驻留在内存的高端，然后修改INT13H的中断向量或其它中断向量，使其向高端的病毒程序，这时即可把原引导程序读到内存中，并把控制权交给它以完成系统的启动。

Here, then, is the code for the loader program.

这里是引导程序的代码。

Zero once the damaged track will be the primary boot hard drive and the partition table information will be seriously damaged, resulting in the hard disk can not boot. 0 tracks damaged judge: System self-test pass, but the boot partition C disc lost or directory is missing, there are laws of the hard disk "... creak ... creak" seek the sound of running SCANDISK scanning C disk, in the first cluster a red "B", or can not find Fdisk the hard disk, DM died in the 0 track, the track such a situation that is zero damage!

零磁道一旦受损，将使硬盘的主引导程序和分区表信息将遭到严重破坏，从而导致硬盘无法引导。0磁道损坏判断：系统自检能通过，但启动时，分区丢失或者C盘目录丢失，硬盘出现有规律的"咯吱……咯吱"的寻道声，运行SCANDISK扫描C盘，在第一簇出现一个红色的"B"，或者Fdisk找不到硬盘、DM死在0磁道上，此种情况即为零磁道损坏！

The main content of the dissertation is designing and realizing the total scheme and frame of system software. The module of the input and output is designed by using the generally I/O of the multichannel buffered serial port to simulated the communication of I~2C bus. The Ping-Pong buffer is brought forward to resolve the problem of the data rate matching. The logic switch function is designed in the programmed logic devices. The data transmission rate is improved by using the DMA and the dual buffer mechanism. The system program self-loading is realized by the design of the self-leading program. Lastly, the dissertation analyzes the characteristic of LLL video and experimentalize with some typical image processing algorithm.

主要对系统软件的总体方案与框架结构进行设计实现，内容包括利用通用串行口模拟I~2C通讯实现输入／输出模块的设计，提出乒乓缓冲结构来解决数据的速度匹配问题，利用可编程逻辑器设计完成逻辑切换控制功能，利用DMA并行传输方式并设计双缓冲结构提高数据的传输速度，设计自引导程序来实现系统程序自加载，最后深入探讨了微光视频图像的特征说明了几种典型的微光图像处理算法的原理，参考这些处理算法设计能在高速视频图像处理器上实现的软件方法，并做了一部分相关的实验研究。

This paper illustrated in this kind of hardware resources disposition,using FLASH memory in system programming technology,designed and programed the electricity boot and writing conformed to the sy.

本文阐述了在这种硬件资源的配置下。利用FLASH存储器的在系统编程技术。设计和编写符合系统要求的上电引导程序和烧写程序。

Secondly the paper takes U-BOOT as the booting systems. It expatiates upon the booting system's processes and function and puts forward developments methods of the booting systems; According to the basic principle of Linux kernel the paper mainly expatiates on the processes, memory management and file system of OS. Furthermore it gives the kernel's start-up processes and replants the OS to the goal system.

其次，本文以U-BOOT为引导系统，对引导程序的程序流程及功能进行研究分析，对引导系统进行了开发；根据Linux内核的基本原理，对操作系统的进程、内存管理以及文件系统进行分析，给出了内核的启动流程，并完成了向目标系统的移植工作。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
