# Write ISO (⚠️ ERASES USB!)
sudo dd if=image-recipe/results/archipelago-3.19-hp-prodesk-x86_64.iso of=/dev/rdiskN bs=1m

# Eject
diskutil eject /dev/diskN
```

## 🧪 Test in VM

```bash
# Install QEMU first
brew install qemu

# Test boot
qemu-system-x86_64 \
  -cdrom image-recipe/results/archipelago-3.19-hp-prodesk-x86_64.iso \
  -m 2048 \
  -boot d
```

## 🏝️ First Boot Setup
