Meta System HF TOP Line 940
Fully drivable by open code over the stock firmware.
Listed by Network UPS Tools (UPS). Host-side drivers communicate with the existing device firmware. Connection and hardware constraints apply; upstream listing is not an OpenDeviceDB hardware test.
Get started
One known way to put open firmware or software on this device, easiest first. Each one links to the project's own instructions.
- Back up your data and settings (and the stock firmware, when the guide says how).
- Check the exact model, hardware revision and firmware version against the guide: a close model may not work.
- Charge the battery or use a stable power supply; do not unplug during the install.
