floppaOS is a free and open-source 32-bit operating system written in C, built entirely from scratch—except for the GNU GRUB bootloader.

This project is meant to be the magnum opus of my programming portfolio, created both for job opportunities and my deep interest in low-level programming.

I chose not to conform to UNIX standards, which are common in OS development. My reasoning? GNU/Linux already exists and represents the peak of UNIX operating systems. Rather than competing with that, I aim to build something distinct from the usual UNIX-based systems.

Obviously, floppaOS is not intended for production use in its current state. OS development is time-consuming, and updates will be inconsistent, especially during this alpha stage.

Contributions and help are always welcome! If you're interested, feel free to fork the project, submit pull requests, or reach out on Discord: @amarat.

Thank you for checking out floppaOS—and if you read all this, I appreciate it!

Note: If you're on Windows, you'll need a UNIX-like environment such as Cygwin to compile the source code.

Run the following command in your terminal:

git clone https://github.com/amar454/floppaos.git

Navigate to the repository directory and compile with:

make all

This will generate an ISO image, which can be attached to a virtual machine or written to a USB device.

To compile and immediately launch the OS in QEMU, use:

make qemu

QEMU is the only vm floppaos is compatible with, due to issues with multiboot mmap on anything else... sorry

3. Clean Up
To remove compiled binaries:

make clean

To remove C and assembly object files while keeping the ISO:

make cleanobj

(This is the recommended step after compilation.)

✅ Simple and lightweight command-line OS
✅ Custom scripting language (fshell)
✅ Memory handler
✅ VGA text mode & graphics (graphics WIP)
✅ Task handler
✅ Basic file system
✅ Command-line scientific calculator (some functions WIP, wrapper not yet complete)

• Runs on minimal hardware
• Completely built from scratch
• Uniqueness factor (Still in progress)
• Thorough documentation
• Focus on security through cryptography
• Small OS size (As of 12/13/2024, floppaOS is only 27.65MB!)
• Unique file system with permissions (Not POSIX-compliant)
