A lightweight, hobbyist x86_32 operating system built from scratch. SecureOS focuses on learning low-level system architecture, kernel development, and bare-metal programming without relying on standard libraries.

• Multiboot Compliant: Boots seamlessly via the GRUB bootloader on x86 architectures.
• Custom Splash Screen: Features direct bitmap graphics support (logo.bmp) initialized right at boot time.
• Streamlined Build System: A unified Makefile automates compilation, linking, and ISO generation.
• Pure Low-Level: Written strictly in C, x86 Assembly and Rust with zero external runtime dependencies.

To compile and run SecureOS, you need a Linux environment (or Windows Subsystem for Linux - WSL) with the following tools installed:

# Ubuntu / Debian setup
sudo apt update
sudo apt install build-essential nasm xorriso qemu-system-x86

1. Clone the repository:

   git clone https://github.com/EngineGames-Development/SecureOS.git
   cd SecureOS

2. Compile the source and generate the bootable ISO:

   make

You can boot and test your freshly compiled secureos.iso directly using QEMU:

qemu-system-i386 -cdrom secureos.iso

• Set up GRUB and Multiboot headers
• Implement automated Makefile build system
• Basic Assembly bootloader entry point
• Implement Interrupt Descriptor Table (IDT) & ISRs
• Create a basic VGA text-mode driver for screen output
• Basic Keyboard driver input handling
• Basic Sound(beep) driver
• PCI-Scanner
• Implement Global Descriptor Table (GDT)
• Basic Sata
• Coming soon

Contributions make the open-source community an amazing place to learn and create. Since SecureOS is in its early architectural stages, any help is highly appreciated!
