Operating System

Caution

Do Not Install on Your Main System

This operating system is under development and not suitable for general use. Installing it on your primary system could potentially lead to data loss or system instability.

For testing purposes only, please use a virtual machine like VirtualBox or VMware.

Operating System

A 32-bit Operating System written from scratch in C++

Status

In the current status, this Operating System can only handle user inputs to type and mouse movements

Installation

In order to build this from source ...

  1. Install dependencies
sudo apt-get install g++ binutils libc6-dev-i386
sudo apt-get install grub-legacy xorriso
  1. Build the ISO image
make mykernel.iso
  1. Run on a Virtual Machine using VirtualBox or VM Ware

Tip

At this point, you can use a Lightweight Operating System like TinyCore Linux, to prepare the disk for testing :

  • Use sudo fdisk <disk ex: /dev/sda> to make a partition table
  • Use a tool like mkfs.vfat to make a FAT32 file-system
  • Mount the disk, and do cd /mnt/sda1
  • Now you can create 2-3 files to try read from
  • It will be a while before we create a Directory Parser, since we'll need to create a standard library using dynamic allocation before we get to
