Hey everyone, I built a small educational toy OS and would love feedback.

I’ve been working on a minimal 16-bit real-mode operating system as a learning project focused on low-level x86 concepts.

Features:

• MIT licensed, fully open source
• 16-bit real mode (legacy BIOS / MBR boot)
• Dual-stage boot process
• Minimal shell environment
• Lightweight design (under 1MB RAM usage typical for real-mode constraints)
• Basic command system interacting with CPU registers
• Work-in-progress: experimental fake filesystem layer

This project is mainly for learning OS development, bootloaders, and low-level system behavior. I’d appreciate any feedback, suggestions, or contributions.
