After you add your custom background image file to the fsebrand.bin file (see Section 8.2, Adding the Custom Background Image File to the FSEBRAND.BIN File), you need to distribute the fsebrand.bin file to devices that have ZENworks Full Disk Encryption enabled.
On a managed device, copy the fsebrand.bin file to the following directory:
c:\windows\nac\sbs
If you have many devices for which you need to do this, you can use ZENworks Configuration Management to distribute the file as a Windows bundle to the devices. For information about creating a Windows bundle that copies a file to a device, see Creating Windows Bundles
in the ZENworks 11 SP4 Software Distribution Reference.
Apply a Disk Encryption policy to the device.
After the policy is applied and the PBA login screen appears, your custom background image is displayed.
IMPORTANT:If you want to apply the custom background image to a device that already has ZENworks Pre-Boot Authentication installed, you must uninstall and reinstall the PBA. The background image is added to the PBA Linux partition (from the fsebrand.bin file) when the PBA is installed and cannot be changed after installation.
To uninstall and reinstall the PBA, modify the Disk Encryption policy to deactivate the PBA, then republish the policy to the device to remove the PBA. After the PBA is removed, make sure the rebranded fsebrand.bin file is in the c:\windows\nac\sbs directory, then reactivate the PBA in the policy and reapply the policy to the device.
