1. What is the jongxie OS project?
======================================
The jongxie OS project is an experimental operating system. The purpose of this project is
Good understanding and learning of the operating system. This project complies with the GPL standard. You only need to follow the above standard.
You can distribute, use, and copy contents of the project at will.
Jongxie OS will initially start from power-on the computer, boot into system protection mode, and complete
To interrupt, device, and file system initialization. Simple characters and images can be displayed on the display device.
. For system structure preparation of jongxie OS, refer to the overall micro-core technology of Linux kernel to complete the memory management
Management, device management, file system, process management, task management, and other functions. This project is not prepared in the first stage.
Supports network and GUI interfaces.
2. jongxie OS development progress
================================
2005.10.10-completed the boot. ASM Section Code The system can load
The required module, device required for initialization, and jump to 0x9000: 0x02000 step
Continued execution.
2005.10.12-complete the coding and debugging of some setup. ASM codes, and the system can get them normally.
The required device information and jumps to the head. ASM Code Section to continue execution.
-After coding and debugging part of the head. ASM code, the system can complete Entry protection.
Necessary initialization work after the protection mode, completed the interrupt controller programming, and can
Normally go to the main function and continue execution.
3. features to be completed in the next step of jongxie OS
======================================
1. The character display function in character mode will be completed
2. Writing of the standard input/output function library
3. Reset interrupt handling Program Global Descriptor Table and Local Descriptor Table
4. Complete the compilation of the debug module to facilitate future program debugging.

5. Current jongxie OS status
================================
Jongxie OS is a pilot system project established in October. However, due to time and energy, only multi-task support and memory management have been completed, and file system support has not yet been processed. Although this project does not have much practical application value, it has good teaching value. You can have a deep understanding of the operating system execution process under the ia32 architecture. Therefore, I want to continue the development of this project, but the strength of a person is limited. I hope more friends on the network can join the development of the project, if you are interested, contact me.
6. Run jongxie OS

System Startup

The system enters the protection mode.

Complete keyboard interruption

Complete Multi-task processing
