DOS
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

关于操作系统：本程序可选用优先数法或简单轮转法对五个进程进行调度。每个进程处于运行R（run）、就绪W（wait）和完成F（finish）三种状态之一，并假定起始状态都是就绪状态W。-On the operating system: This procedure may choose to use the priority number of law or simple rotation on the five process scheduling. Each process is running R (run), ready W (wait) and the completion of F (finish), one of three states and assume that the initial state is a state of readiness W.

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
