MONA是为数不多的C++语言编写的一个很小的操作系统，这里是它的源代码。mona的可执行文件的格式其实是PE格式的，和windows可执行文件的格式一样。

为了能放在软盘的1.44M空间里，那些*.ex2 等都经过了压缩。可以用winrar解压，然后用PE工具查看文件的进口表和出口表等信息

前面的几个版本主要是实现内核和控制台。

0.20之后的版本主要是实现了GUI和系统dll，字体处理等，做了几个不同的GUI。每个都有一些特点。

这个操作系统内核的c++类代码值得一看-MONA are among the few prepared by the C language, a small operating system, here is its source code. Mona executable file format is the format of PE and windows executable file formats like. To be able to put the floppy disk 1.44 M space, and so those *. ex2 after compression. Winrar can unpack, Then PE tool to view the document table of imports and exports, and other information table in front of several versions of the kernel is the main console and . After the 0.20 version is the main GUI and system dll, fonts, and so on, done several different GUI. Each has some unique characteristics. The operating system kernel code c category eye-catcher
