RomOS

This repository contains a simple OS code.

Prerequisites

To assemble and run the OS, you'll need the following:

• NASM (Netwide Assembler): An assembler for x86 assembly language.
• QEMU (Quick EMUlator): A virtual machine emulator.
• Cross Compile GCC. See GCC Cross-Compiler for more information.

Usage

1. Clone the repository and navigate to the project directory.

2. Build the OS code:

   sudo chmod +x ./build.sh  # Grant exec permission
   ./build.sh

3. Run the OS using QEMU:

   qemu-system-x86_64 -hda ./bin/os.bin

   This command runs QEMU and boots the virtual machine from the os.bin file.

Customization

• Feel free to explore and modify the code to add additional functionality or experiment with different features.

Notes

• Make sure to use appropriate versions of NASM and QEMU that are compatible with your system.

• The code is intended to be run as a boot sector and assumes that it will be loaded into memory address 0x7C00. Running it directly on a host operating system may have unintended effects.
