Program Description

This program is an operating system development project on 32-bit architecture. In this milestone, we have developed OS interrupt system, keyboard and disk drivers, filesystem using "FAT32 - IF2230 Edition".

Required Program

Here are the required programs you need to prepare to run the program in this repository:

Required Program	Reference Link
C	C Installation Guide
Visual Studio Code	VSCode Installation Guide

---

It is required to compile and run this OS-32bit from LINUX OS. You can use Windows Subsystems for Linux (WSL) to substitute the LINUX OS.

How to Run The Program

1. Clone this repository (skip if the step is done)
   

git clone https://github.com/Sister20/if2230-2023-ded_os_is_ded.git

2. Change the current directory into the cloned repository
   

cd if2230-2023-ded_os_is_ded

3. Run command

make start

How to Compile The Program

Under ideal circumstances, you just need to use the command make start to run OS-32bit as listed in How To Run The Program. If you modify some of codes from the OS-32bit source code, you need to run the subsequent steps to compile the modified OS-32bit into the executables.

1. Clone this repository (skip if the step is done)
   

git clone https://github.com/Sister20/if2230-2023-ded_os_is_ded.git

2. Change the current directory into the cloned repository
   

cd if2230-2023-ded_os_is_ded

3. To only compile OS-32bit source code without run the executables

make build

4. To compile and run OS-32bit source code

make run

5. To format disk used in OS-32bit

make disk

WARNING: Your OS-32bit source code must be warning-free since all warnings will be converted to errors.
