PC兼容机硬件工作原理比如8259A,8253, 8042UART等硬件2. Intel 32位 运行模式工作原理寻址方式3. 传统C语言4. 一些Intel asm基础。5. 会使用Linux操作系统懂得Linux系统的基本操作。推荐参考书籍《UNIX操作系统设计》http://www.china-pub.com/computers/common/info.asp?id34*《UNIX环境高级编程》http://www.china-pub.com/computers/common/info.asp?id30《操作系统设计与实现》MINIXhttp://www.china-pub.com/computers/common/info.asp?id2033《IBM PC 汇编语言程序设计》http://www.china-pub.com/computers/common/info.asp?id7721*《深入理解计算机系统》http://www.china-pub.com/computers/common/info.asp?id18133《Linux权威指南》http://www.china-pub.com/computers/common/info.asp?id1174《Linux Assembly Language Programming》ftp://plinux.org/pub/linux/docs/ ... age_Programming.pdf*《Intel 80386 Programmer;s Reference Manual》ftp://plinux.org/pub/linux/docs/Intel_80386_Manual.pdf*《The C Programming Language》ftp://plinux.org/pub/linux/docs/The_C_programming_Language.rar加星号“*”者为重点推荐读物如果有些忘了就请先花哪怕一天时间将这些基础知识先浏览一遍在看本书。硬件方面可参考教科书。Intel 32 mode 可见Intel 386 manual内核代码中用到的汇编程序as86和ATT语法可参照以下一些文档。-------------------------------------------------------------MINIX 汇编手册: http://www.oldlinux.org/oldlinux/viewthread.php?tid291NASM 汇编手册: http://www.oldlinux.org/oldlinux/viewthread.php?tid877as86 在线手册: http://www.oldlinux.org/oldlinux/viewthread.php?tid1895ld86 在线手册http://www.oldlinux.org/oldlinux/viewthread.php?tid1428/*****************************************//* 本站资源 *//* http://oldlinux.org/Linux.old/ *//*****************************************/如果你具有大学计算机本科或以上学历那么你可以在适当复习以上知识后就能顺利看懂本书。如果你是在读本科计算机系的学生那么在学习过操作系统课程或者正在学习时只要复习一些有关Intel PC机组成原理就应该很顺利地理解本书并能很好地帮助你理解操作系统的基本原理。如果你是其它专业在读本科学生那么你可以首先自学一些有关操作系统的理论知识和计算机微机原理课程如果没有学过的话了解一些操作系统的基本术语再继续学习本书。如果你是一个专科学生那么你首先需要准备的知识与一个非计算机本科生所要做的一样。如果你是一个中学毕业的学生那么你可以先自学一些《计算机原理》、《微机原理》、《C语言》、《英语》等基本课程然后再继续阅读本书。当然也可以把摊子铺开同时阅读注意 无论你现在的学位或学历怎样这都不是主要问题。关键在于努力和刻苦。而兴趣是学习的最好动力之一。即使你没有任何学位只要识字能上网那么你面前的道路还是宽广的。“世上无难事只要肯登攀”。---------------------------------------------------------------------------------------------源代码浏览工具介绍http://www.oldlinux.org/oldlinux/viewthread.php?tid1470 在本机上阅读源代码可以使用redhat 的snavigator或Source Dynamics的Source Insight软件。snavigator是免费的source Insight可以去www.sourceInsight.com去下载。或者在此处下载http://oldlinux.org/download/tools/si350.rar (3.2MB)http://oldlinux.org/download/tools/Release-SN51E-win32.zip (7.8MB)http://oldlinux.org/download/tools/src2html/Source Insight的使用方法可参见文章http://www-900.ibm.com/developer ... t/tip17/index.shtml 也可以使用本站网页上提供的再线交叉引用阅读程序http://oldlinux.org/lxr/http/source/在阅读本书时最好在计算机中安装这两个软件之一边阅读书中注释边浏览代码。------------------------------------------------------------------------------------------------lxr设置方法介绍1How to make your own Cross ReferenceBy qhshang at 163.comIt is a long long time to gen xref for it, a not so long time to glimpse-index it.If you are lucky enough to make lxr.conf done like it on this host in half an hour, do NOT drop me a mail:-)----------------------------------------Install lxrModify Makefile to customize the PERLBIN and INSTALLPREFIX, to indicate the perl program and where you install lxr.then #36; make installTo generate your reference for files in Your_dir:#36; genxref Your_dirwhile genxref is in lxr/binIn my practice using genxref, locale should be set to C, en_US.utf-8 is not ok.I don;t know why, because I don;t read the perl script throughly.----------------------------------------Install glimpse:First make glimpse, then cp bin/{glimpse,glimpseindex} to /bin or /usr/binGenerate index using glimpse:#36; glimpseindex -H .

You are running the test suite under user ;root;.Apache cannot spawn child processes as ;root;, thereforewe attempt to run the test suite with user ;nobody; (99:99).The problem is that the path:/root/mod_perl-1.99_10/tmust be ;rwx; by user ;nobody;, so Apache can read and write under thatpath.There several ways to resolve this issue.
