3. Hardware detection runs automatically
4. Services start automatically
5. Access UI at `http://<device-ip>:8100`

## Verification

After flashing, verify the build:

```bash
# Check ISO integrity
sha256sum results/archipelago-0.1.0-start9-pure-x86_64.iso

# View build manifest
cat results/BUILD_MANIFEST_start9-pure.txt

# Mount ISO to inspect (Linux)
sudo mount -o loop archipelago-0.1.0-start9-pure-x86_64.iso /mnt
ls -la /mnt
cat /mnt/etc/archipelago/hardware.toml
sudo umount /mnt
```

## Troubleshooting

### Build Fails
```bash
# Clean build artifacts
rm -rf results/ build/ apks/ aports/

# Try again
./build-for-hardware.sh start9-pure iso
```

### Wrong Hardware Detected
Check hardware profile after boot:
```bash
cat /etc/archipelago/hardware.toml
cat /var/log/archipelago-hardware.log
```

### Boot Issues
- Verify ISO checksum
- Try different USB port
- Check BIOS/UEFI settings:
  - Enable UEFI boot
  - Disable Secure Boot (for now)
  - Enable USB boot
  - Set boot order

### Performance Issues
View hardware optimization log:
```bash
cat /var/log/archipelago-hardware.log
dmesg | grep -i archipelago
journalctl -u archipelago
```

## Advanced Usage

### Custom Hardware Profile

Create custom profile for your hardware:

1. Copy generic profile:
   ```bash
   cp -r alpine-profile/overlay alpine-profile/overlay-myserver
   ```

2. Edit hardware config:
   ```bash
   vim alpine-profile/overlay-myserver/etc/archipelago/hardware.toml
   ```

3. Build with custom profile:
   ```bash
   HARDWARE_TARGET=myserver ./build-for-hardware.sh myserver iso
   ```

### Build All Targets

Build for all supported hardware:
```bash
#!/bin/bash
for target in start9-pure hp-prodesk dell-optiplex generic; do
    echo "Building for $target..."
    ./build-for-hardware.sh $target iso
done
```

### Automated Testing

## Building Multiple Targets

To build for all your hardware:

```bash
# Build Start9 Server Pure image
./build-for-hardware.sh start9-pure iso

# Build HP ProDesk image  
./build-for-hardware.sh hp-prodesk iso

# Build Dell OptiPlex image
./build-for-hardware.sh dell-optiplex iso

# You'll get separate ISOs optimized for each
```

Each ISO is independent and optimized for its target hardware!
