Appendix A

A system with UEFI Secure Boot enabled will prevent the installation of unsigned third-party drivers. Proceeding will require generating a Machine-Owner Key (MOK) for the Extensible Virtual Display Interface (EVDI) kernel module.

1. After executing the .run file, a terminal prompt will indicate that the system has Secure Boot enabled.
    
2. Selecting o.k. enables DKMS to automatically enroll the key into the system firmware. The user will be prompted to generate a onetime password, followed by a prompt to re-enter password as confirmation.

3. A system restart will be required to complete the MOK enrollment. Type the command sudo reboot into the terminal to complete this action.
4. The system will boot into the MOK Management GUI. Select Enroll MOK > Continue > Yes.
5. You will now be prompted to input the password from Step 2 above.
