Welcome to join the public evaluation program of ZimaOS. ZimaOS is evolved from CasaOS, and we have built a release version of ZimaOS for better hardware compatibility and update experience. It will perfectly adapt to the Zima series hardware and also be compatible with x86-64 systems with UEFI.
It is built using Buildroot and has stable OTA update functionality. Based on CasaOS, we have built a series of new applications. You can find the specific differences between it and CasaOS from the table below:

2. Download the image
- Open [`Releases`](https://github.com/IceWhaleTech/ZimaOS/releases/latest) and download the installer image.
- Pick the file named `zimaos_XXXXX_installer.img` (`XXXXX` varies by version).
3. Create the USB installer

1) Launch Etcher.
2) Select the downloaded `*.img` file.
3) Choose the target USB drive (verify the correct device).
4) Click Flash, wait for completion, then safely eject the USB drive.
4. Install ZimaOS
- Insert the USB installer into the target device (Zima hardware or generic x86‑64 PC).
- Open the BIOS/Boot Menu and boot from the USB device in UEFI mode.
- Follow the on‑screen installer to select the target disk and confirm installation (this erases the disk).
- When installation completes, reboot as prompted and remove the USB installer.
- Boot from the installed disk (UEFI) to start ZimaOS and finish the initial setup.
