Overview Version 0.7

OS_32Bit is a 32-bit operating system designed to showcase technical capabilities and serve as a platform for learning and collaboration. It is entirely open-source, inviting contributions from the developer community.

Core Components:

• Kernel Entry
• Virtual Memory
• Multitasking (Round Robin)
• Task Switching
• Interrupt Handling (IDT)
• Global Descriptor Table (GDT)
• Task State Segment (TSS)
• Utility Libraries
• Input/Output
• Memory Detection
• Time and Date
• Test and Debug

Installation

This section provides the necessary steps for installing the operating system, including system requirements, installation guides, and booting instructions.

• Do Fork + Clone Repository:

  gh repo fork    https://github.com/IlanVinograd/OS_32Bi  t.git --clone=true
  gh repo star IlanVinograd/OS_32Bit

• System Requirements: A basic development environment with Docker installed.

• For GUI QEMU: Required install -> VcXsrv, When you start VcXsrv, choose "Multiple Windows" and ensure that "Disable access control" is checked.

• Installation Guide: Follow the steps below to build and run the OS using Docker.

• Booting Instructions: Run the bootloader through Docker and QEMU.

Build the Docker Image

To build the Docker image, use the following command:

cd Code

docker build -t os_32bit .

cd ..

Run the Project

• Run the project using either CMD or PowerShell with the following commands.

  CMD

  docker run --rm -e DISPLAY=host.docker.internal:0.0 -v %cd%\Code:/usr/src/bootloader os_32bit
  

  OR

  Powershell

  docker run --rm -e DISPLAY=host.docker.internal:0.0 -v "$(Get-Location)/Code:/usr/src/bootloader" os_32bit
  

Cleaning Up Containers

• You can stop and remove all running and stopped containers using the commands below.

• NOTE: Always clean the containers to free up resources!

  CMD

  for /f "tokens=*" %i in ('docker ps -q') do docker stop %i
  for /f "tokens=*" %i in ('docker ps -a -q') do docker rm %i
  

  OR

  Powershell

  docker stop $(docker ps -q) ; docker rm $(docker ps -a -q)
  

Important Note: Save and Run

• After making changes to your code, always save your changes before testing.

• To test the updated code, you must run the docker run command again to start a new container with the latest changes.

  CMD

  docker run --rm -e DISPLAY=host.docker.internal:0.0 -v %cd%\Code:/usr/src/bootloader os_32bit
  

  OR

  Powershell

  docker run --rm -e DISPLAY=host.docker.internal:0.0 -v "$(Get-Location)/Code:/usr/src/bootloader" os_32bit
