-------------------------------------------------------------------------------- 1 | 添加了haribote.nas文件，修改了makefile 2 | makefile的步骤： 3 | 1.创建myos.img（和前面几次一样） 4 | 2.将haribote.nas编译为haribote.bin 5 | 3.挂载myos.img 6 | 4.复制haribote.bin到myos.img上 7 | 5.卸载myos.img 8 | 9 | 运行步骤: 10 | make clean 11 | make 12 | sudo make copy 13 | make run 14 | 15 | 用16进制编辑器hexedit查看： 16 | hexedit myos.img 17 | 发现在地址为0000:2600的地方有数据了！成功! 18 | 19 | Attention! 20 | 1.hexedit需要下载并安装：sudo yum install hexedit -y 21 | 2.sudo make copy这一步是必须的，因为要拷贝，同时需要sudo权限 22 | 3.另一个有数据的地址为0000:4400,发现和书上不一样。网上查过别人的帖子，基本上都是4400.估计是《30天》使用的工具和我们不太相同，我们这个4400经过考证应该是正确的。原因如下： 23 | 24 | 查看了微软的硬件白皮书（fatgen.doc），发现这个0x4400是可以计算出来的： 25 | 第一个公式： 26 | RootDirSectors = ((BPB_RootEntCnt * 32) + (BPB_BytsPerSec – 1)) / BPB_BytsPerSec; 27 | 这里需要注意，要round up取整。 28 | 第二个公式： 29 | If(BPB_FATSz16 != 0) 30 | FATSz = BPB_FATSz16; 31 | Else 32 | FATSz = BPB_FATSz32; 33 | FirstDataSector = BPB_ResvdSecCnt + (BPB_NumFATs * FATSz) + RootDirSectors; 34 | 预先设定的值中，BPB_FATSx16等于9，BPB_ResvdSecCnt为1， BPB_NumFATs为2， RootDirSectors上面计算得到是15，那么： 35 | FirstData=34 36 | 那么，34*512，也就是4400H那里了（4400H/200H=22H=34, 200H就是512k） 37 | 38 | 39 | 这里还有一个问题，就是在计算RootDirSectors的时候，感觉分子上的（512-1）没有什么用处。网上有人这样解释： 40 | “"字节对齐作用",解释比较简单和牵强,不过你这句话提醒了我,我想微软的这个公式是同时用于计算FAT16和FAT12用的, 41 | 对于FAT16本身"(BPB_BytsPerSec – 1)/BPB_BytsPerSec"是没必要的,而对于FAT12由于它每个表项是1.5个字节,如果 42 | 应用不当的话有可能会造成"跨越扇区边界"的问题,故而保留了1个扇区,不知这样认识对不对,请朋友们继续发表看法. ”（ref：http://bbs.eeworld.com.cn/thread-131851-1-1.html） 43

/day3.7/readme: -------------------------------------------------------------------------------- 1 | day3.6和day3.7因为内容上是连贯的，所以就一起写在这里。 2 | 3 | 需要在hello.nas中添加跳转到0xc400的指令，以及将CYLS的值写入0x0ff0的地址处 4 | 5 | 为什么是0xc400? 6 | 我们前面分析过了，0x7c00-0x7dff是ipl，也就是第一个扇区，0x7e00-0x7fff是ipl的堆栈和数据区域，0x8000-0x81ff是ipl的备份区。 7 | 对于ipl备份区域的这个说法，我也是在百度贴吧找到的，个人感觉不是很靠谱。ipl明明就是写入到了前32k中的最后1k了嘛！也就是0x7c00-0x7fff 8 | 不过我们可以这么想：0x8000-0x81ff就相当于ipl,也就是软盘的第一个扇区的内容复制到的地址部分，那么0x8200开始就是第二个扇区，以此类推。 9 | 这样看来，软盘上地址为addr的内容会被复制到内存的addr+0x8000的地址处。 10 | 根据hexedit查看myos.img的结果，以及前面关于0x4400的公式推导，可以知道：软盘上地址为0x4400的数据区域（也就是操作系统的kernel处）对应的内存地址应该是0x4400+0x8000，也就是0xc400 11 | 12 | 因此，在hello.nas中应当跳转到0xc400处，而haribote.nas的作用，就相当于最初级的kernel。 13 | 因此，接下来的任务，就是写自己的kernel 14 | -------------------------------------------------------------------------------- /day3.8/.hello.nas.bak.swp:

-------------------------------------------------------------------------------- 1 | day3.9 2 | 这里是导入C语言了。原作者用了一堆工具：cc1.exe,gas2nask.exe等。 3 | 这些工具是从linux下改造到windows下的。 4 | 为什么不在linux下用linux下的工具呢？ 5 | 这也正是我动手在fedora下实践《30天》的原因。 6 | 7 | 创建kernel目录，在里面添加entry.S，screen.c，mmu.h等代码。和原作者说的一样，这里我们不求理解，要到后面才能完全理解这里做了什么。 8 | 这里唯一的目标就是，能够导入C语言并使用。 9 | makefile对应做了修改：添加了kernel目录下的makefile；外层的makefile调用内层的makefile； 10 | 运行的时候也相应调整为（在外层运行）: 11 | make 12 | sudo make copy 13 | sudo make run (这里现在也需要权限了) 14 | 15 | 注意里层的makefile编写的时候，gcc的参数-m32表示编译为32位，因为x86架构无法运行64位程序；ld的参数-m elf_i386也是为32位设定的。 16 | 如果你用来开发的电脑是32位的，那么不写这两个参数也是ok的。 17 | 18 | 原作者的C语言代码为bootpack.c,这里修改为main.c，并且函数名因为entry.S中的设定，main.c中修改为bootmain 19 | 20 | 21 | ====================== 22 | 在代码的调式过程中，遇到一个问题，已经解决了，分享一下： 23 | makefile中的run部分，用的是qemu命令： 24 | qemu-system-i386 file-kernel,if=floppy 25 | 但是当我写成: 26 | qemu-system-i386 file-kernel,

《30天自制操作系统》在Linux下的实践。参考[CSDN米油](http://blog.csdn.net/h397916230)的代码完成(很不幸，此博客现在无法打开)，代码命名方面尽量和《30天》中保持一致。 2 | 3 | 用到的技能： 4 | 1.简单的bash操作，包括`ls`, `cd`, `cp`, `mv`, `rm`, `mount`, `dd`, `cat`等 5 | 2.编译器gcc、nasm的基本使用 6 | 3.make工具的简单使用，[参考教程](https://zchrissirhcz.github.io/blog/post/62ce2c40.html) 7 | 4.C语言、汇编语法 8 | 9 | 用到的工具软件： 10 | gcc, make, nasm, qemu, vim(非必须) 11 | 12 | 运行环境: 13 | Fedora20-x86\_64下运行良好 14 | --------------------------------------------------------------------------------
