NovaOS – A 16-bit hobby OS in Assembly & C (Looking for feedback)
Posted: Fri Jul 24, 2026 8:18 am
Hello OSDev community,
I'm 11 years old and I've been working on a 16-bit hobby operating system called NovaOS for several months.
It's inspired by MikeOS and currently includes:
- Command-Line Interface (CLI) with commands like DIR, CAT, COPY, DEL, HELP, and SYSINFO
- BASIC interpreter
- Simple text editor (NovaPad)
- FAT12 filesystem support
- Basic graphical launcher (still in development)
I'm currently facing challenges with:
1. Transitioning from 16-bit Real Mode to 32-bit Protected Mode
2. Improving the graphical interface (GUI)
3. Debugging memory management issues
If anyone has experience with these topics, I'd really appreciate your advice!
Source code & ISO: https://github.com/danieldevir/NovaOS
I've also reported a few bugs to Google (Android VRP), Qualcomm, and the Linux kernel (Bugzilla #221773 and #221775).
Thank you for your time! Feedback and suggestions are very welcome.
