这是ucore的实验1：系统软件启动过程。实验目的：操作系统是一个软件，也需要通过某种机制加载并运行它。在这里我们将通过另外一个更加简单的软件-bootloader 来完成这些工作。为此，我们需要完成一个能够切换到x86 的保护模式并显示字符的bootloader，为将来启动操作系统做准备。proj1 提供了一个非常小的bootloader，整个bootloader 的大小小于512 个字节，这样才能放到硬盘的主引导扇区中。通过分析和实现这个bootloader，读者可以了解到：基于分段机制的存储管理、设备管理的基本概念、PC 启动bootloader 的过程、bootloader 的文件组成、编译运行bootloader 的过程、调试bootloader 的方法、在汇编级了解栈的结构和处理过程、中断处理机制、通过串口/并口/CGA 输出字符的方法。文件中包括源代码、实验指导书和实验报告。-Ucore is a small operating system for learning, the " Sparrow" contains the virtual memory management, process management, processor scheduling, synchronization mutually exclusive, inter-process communication, file system and other major kernel functions, the total amount of kernel code ( C+ asm) no more than 5K lines.

This is ucore experiment 1: the system software boot process. Purpose: the operating system is a software, but also need some mechanism to load and run it. Here we will adopt another more simple software-bootloader to complete these tasks. To this end, we need to be able to complete a switch to the x86 protected mode and display the characters bootloader, the operating system to start to prepare for the future. proj1 provides a very small bootloader, the bootloader is less than 512 bytes in size, so as to put the hard disk master boot sector. Through the analysis and to achieve this bootloader, the read
