A minimal bare bones operating system based on a monolithic kernel design written purely in Assembly language.
Legacy boots from a pre-built disk image with planned support for GRUB multiboot.
Kernel size: 8 KiB
Current OS Features
- Single threaded processes
- CLI
- Preemptive scheduler
Minimum Hardware Requirements:
- RAM: 20 MiB
- CPU: x86-64
Microprocessors tested on:
- Intel Pentium 4
- Intel Core 2
I want to say a big thanks to the Flat Assembler community (http://flatassembler.net) for their help and advice - The boards are full of great examples and I hope they inspire more to take up assembly programming.

Want to jump right in and run minOS? Follow these simple steps...
Install the required software on your GNU/Linux distribution:
Ubuntu/Debian: apt-get install bochs fasm
Arch: pacman -S bochs | (install fasm from the aur, for example using aurget: aurget -S fasm)
Clone this repo:
git clone https://github.com/triforce/minos.git
Switch to the minos build directory and build the image:
cd minos/build && make
Switch back to the root dir and run minOS in the Bochs emulator:
cd .. && bochs -f emulators/bochs-<ubuntu|arch>
