Show HN: Aurion OS – A 32-bit GUI operating system written from scratch in C

Hi HN! I'm 13 and I built Aurion OS as a solo learning project over 14 days (~12 hours/day).

It's a 32-bit x86 operating system written entirely in C and x86 Assembly with no external libraries.

What it has: Custom bootloader and kernel VESA framebuffer graphics (1920x1080, double-buffered) Window manager with draggable, overlapping windows macOS-inspired dock with transparency PS/2 keyboard and mouse drivers ATA hard drive driver with filesystem PCI bus enumeration RTL8139 network driver (WIP) Real-time clock Runs on just 16MB RAM (up to 10 windows simultaneously)

Built-in apps: Terminal (with DOS mode), Notepad (save/load), Calculator, Paint (multiple colors and brush sizes), Snake game, Settings (theme switching), and System Info.

Currently works best on QEMU, VirtualBox, and VMware. Real hardware support is still a work in progress.

Next goal: TCP/IP networking stack.

I'd love any feedback, suggestions, or criticism. This is my first OS project and I learned mass amounts while building it. Happy to answer any technical questions!
