## 🧩 1. Basic Information | Field | Description | | --- | --- | | OS Name | MenuetOS (also known as MeOS) | | Developer | Ville M. Turjanmaa (original), plus community | | First Released | ~2000 | | Latest Version | Menuet64 v0.99.98 (2024 updates for x86-64) | | License Type | Menuet64 is Freeware (source partially open); Menuet32 has more open community ports | | Supported Platforms | x86 (32-bit) & x86-64 (64-bit) | | Still Active? | ✅ Yes (especially Menuet64, under active updates by Ville) | ## ⚙️ 2. Kernel & Architecture **Kernel Type:** Monolithic **Based On:** Written completely from scratch, entirely in FASM (Flat Assembler) x86 assembly language Architecture: Original was x86-32 (Menuet32) Now actively developed as Menuet64, fully 64-bit native **File System Support:** FAT12, FAT16, FAT32 native; reads from USB and local disks Can boot from floppy, CD, USB, or directly from a hard disk ## 🌟 3. Key Features Tiny footprint: Core OS fits on a 1.44 MB floppy (still with GUI, network, and apps) Full GUI from the start: Boots directly to a graphical desktop, no text mode login Multitasking & multithreading with preemptive scheduling Includes a graphical text editor, image viewers, games, system monitors, and a simple web browser TCP/IP stack with Ethernet support GUI API accessible directly from assembly for making small, fast apps Menuet64 adds 64-bit support, more memory, and modern drivers ## 📈 4. Version History & Important Milestones ✅ | Milestone / Version | Year | Description | | --- | --- | --- | | MenuetOS first demo | ~2000 | Showed a full GUI multitasking OS on a floppy | | Menuet32 stable versions | Early 2000s | Became popular among hobby OS developers | | KolibriOS fork | ~2004 | Community forked to add more features, translations | | Menuet64 | ~2010± | Shifted to 64-bit architecture, supporting more RAM and modern CPUs | | Latest builds | 2020s± | Ville continues updating with new drivers & bug fixes | ## 🎯 5. Target Audience & Use Cases Hobbyist OS developers: Perfect for studying low-level assembly OS design Retro PC enthusiasts: Runs on extremely low-spec machines (Pentium-class CPUs with 16 MB RAM) Quick boot demos or hardware test: Can boot instantly off a floppy or USB to test old hardware Embedded GUI demos: Minimal overhead for running a graphical app or kiosk-like system ## ✅ 6. Pros & Cons | Pros | Cons | | --- | --- | | Tiny size, boots instantly even on old PCs | Written entirely in assembly, harder to maintain or port large apps | | Completely self-contained GUI & network stack | Limited driver support for modern hardware (WiFi, advanced GPUs) | | Excellent for learning low-level OS internals | No POSIX layer, so limited software portability | | Can run from floppy, CD, USB with no install | Small user base, niche community | ## 🎨 7. UI Demo & Visuals Colorful GUI desktop after boot (with analog clock, taskbar, system stats) File manager navigating FAT folders Basic text editor editing .ASM or .TXT files Playing simple games (like Tetris clones, card games) Tiny web browser opening a page over Ethernet ## 📦 8. Ecosystem & App Support Mostly Menuet-native apps, written in FASM with direct system calls Comes with sample games, calculators, paint, music player Can run TCP/IP stack for web browsing or simple servers Some community-created small apps & drivers on forums and archives ## 🔐 9. Security & Updates Single-user system, no concept of user accounts or access permissions Extremely small codebase means minimal attack surface (but also minimal defenses) Updates come as floppy or ISO images directly from the MenuetOS site Community sometimes shares bug-fixed or hardware-patched builds ## 🌍 10. Community, License & Development License: Menuet64 is Freeware (source available under specific conditions), Menuet32 partially open with examples Active forums on sites like OSDev, plus the official MenuetOS forum Frequently cited in OS development courses as an example of ultra-low-level implementation Inspires forks like KolibriOS, and many small experimental assembly-based OS projects
