bootOS is a monolithic operating system written in x86 assembly that fits entirely within a single 512-byte boot sector. It provides a minimal filesystem and system services (load, save, delete files, keyboard/screen I/O) for 8088-compatible PCs.
Use cases
- boot a tiny operating system from a floppy disk image
- learn x86 assembly and boot sector programming
- experiment with a minimal filesystem in 512 bytes
- run small programs as boot sectors on emulators like DOSBox or QEMU
- teach operating system fundamentals with a tiny codebase
When to choose
- you want an educational, minimal OS that fits in one boot sector
- you need a tiny x86 boot-sector demo compatible with the original IBM PC 8088
- you're teaching or learning low-level OS and filesystem concepts
When to avoid
- you need a general-purpose operating system with drivers, multitasking, or networking
- you require a modern filesystem with directories, large files, or long filenames
- you want a production-ready OS for real workloads
