2. Confirm the BIOS version is one of the below or greater
     * BOX IDG.21 v1.0.1.0.14
     * BOX IDG.23 v1.0.1.0.14
          * If BIOS does not match, Cheetah will need to be returned to Data-Tech for repair
 
3. Navigate to Advanced > Trusted Computing > Security Device Support; change from Disabled to Enabled
