DOS操用系统源代码,C语言编写,对操作系统的认识有很大的帮助....

DOS - ç ，它的内核也是FreeDOS的内核。并在此基础上进行了一定的修改，使其更加实用。 FreeDOS的是项目设计 提供替代到MS - DOS，PC的DOS的和DR - DOS的自由 。-DOS-C started in 1988 as an experiment in writing device drivers in C for Microsoft s MS-DOS. Both block and character device drivers were written, along with special C data structures to match the MS-DOS request packet. It was then recognized that using the same techniques, an operating system could be written that would take advantage of the C language features and would require much less time to develop than the traditional assembly language techniques. Although UNIX had proven this earlier, it was not tried with a traditional pc operating system. At this time, a minimal operating system using the device drivers written earlier along with a new 8086 interrupt API was developed. It was called XDOS and proved to be a functional operating system. This new operating system was used to develop booting techniques and a C library SDK was dev

操作系统课程设计设计文档题目一的内容实现UP、DOWN原语产生3个进程：两个进程模拟需要进入临界区的用户进程。当需要进入临界区时，显示：“进程x请求进入临界区…”，同时向管理进程提出申请；申请返回，表示进入了临界区。在临界区中等待一段随机时间，并显示：“进程x正在临界区…”；当时间结束，显示：“进程x退出临界区…”,同时向管理进程提出退出申请；当申请返回，显示：“进程x已退出临界区。”一个进程作为原语的管理进程，接受其他进程的临界区进入请求：如果允许进入，则根据DOWN 原语的操作步骤设置相应变量，然后返回； 如果不允许进入，则进入循环等待，直到允许为止； 退出时模拟UP 操作。 进程间通信可以采用信号、消息传递、管道或网络通信方式。-Operating system design documents subject curriculum design content of the UP, DOWN primitives have three process
