Check processor and EFI firmware compatibility¶

Before installing Clear Linux* OS, check your host system’s processor and EFI firmware compatibility. To check compatibility, choose one of the following paths:

From a system with a Linux* OS installed, follow the instructions to Check compatibility.
From a non-Linux OS, first Install Clear Linux* OS from the live desktop and then follow the instructions to Check compatibility.

Note

This does not check other system components (for example: storage and graphics) for compatibility with Clear Linux OS.

Check compatibility¶

Download the clear-linux-check-config.sh file.

If a browser is not available, use:

curl -O https://cdn.download.clearlinux.org/current/clear-linux-check-config.sh

Make the script executable.
```
chmod +x clear-linux-check-config.sh
```

Run the script.

Check to see if the host’s processor and EFI firmware is capable of running Clear Linux OS.
```
./clear-linux-check-config.sh host
```
Check to see if the host is capable of running Clear Linux OS in a container.
```
./clear-linux-check-config.sh container
```

The script prints a list of test results similar to the output below. All items should return a SUCCESS status. This example indicates the host’s processor and EFI firmware support running Clear Linux OS.
