🔥 HellSpawnOS 🔥

a handcrafted OS because why not 😈

HellFireOS is a from-scratch hobby operating system written in C + x86 ASM. No libc. No BIOS hand-holding. Just raw CPU vibes.

This project exists because:

• learning OS dev is cool
• pain is temporary
• serial logs are forever

---

✨ Current Features

• ✅ Custom bootloader
• ✅ Protected mode (32-bit)
• ✅ Serial output (COM1)
• ⌨️ Keyboard (WIP)

---

❌ Not Implemented (Yet)

• ❌ Filesystem
• ❌ Memory allocator (malloc/free)
• ❌ Syscalls
• ❌ User mode
• ❌ ELF loading
• ❌ libc / unistd.h

---

🧪 Running (QEMU)

make
make run

Serial output is your best friend 🫂

---

🧭 Roadmap

• Keyboard driver
• Simple heap allocator
• Basic filesystem
• Syscall interface
• Userspace

---

⚠️ Disclaimer

This OS is:

• not secure
• not stable
• not fast
• not POSIX
• not sane

But it boots, and that’s what matters 💪🔥

💖 Why?

Because writing an OS teaches you more than 100 tutorials ever will.

Also because it’s funny.
