Hi Product Hunt! 👋 Ever wanted to peek inside paging, interrupts, and ATA without 30-year-old C cruft? Daxo OS is a clean, mostly-safe Rust playground where you can actually see how a kernel ticks – and break it without breaking your host. After 2.5 months of late nights, it finally does multitasking, handles keystrokes, and reads sectors via PIO. ⚡ Preemptive multitasking with idle halt – even on bare QEMU. 🧠 4-level paging with isolated user tables. 💾 ATA PIO driver (DMA is the next boss fight – and I’m stuck). The DMA controller is my current wall. If you’ve ever debugged bus mastering – please glance at the code or open an Issue. I’ll buy you a virtual coffee. This is for Rustaceans who want to learn OS dev, for tinkerers who miss the 90s, and for anyone who thinks unsafe should be an exception, not a rule. Check out the repo, drop a ⭐️ if you like the rabbit hole, and feel free to open an Issue if you find a bug: 👉 https://github.com/daxo-develope...
