How can I create and deploy a customized Pre-Boot Background image to be displayed at preboot?
Issue:
Many customers wish to have their company's branding reflected in the background screen that appears at Pre-Boot. What is the process to roll out Installation Packages that will include such a customized background?
Solution:
The details of this can be found in the section of the SES User Guide entitled "Text, Color and Logo Options for Boot Logon (PBA)", some of which is repeated below.
Boot text and color options control the way Boot Logon appears on all client devices that install the installation package using a given profile. The options enable you to customize Boot Logon to reflect information relevant to your enterprise.
To access the options, open the Profile screen and click on the button entitled "Boot text and color".
To define a customized background for a Windows device, the graphic file needs to meet these requirements:
24 bit .bmp format
1024 x 768 pixels
when zipped (SecureDoc zips the file for you), it can be no larger than 0.5MB (you will be warned if your file exceeds this size)
Note: For a Mac device, the file should be in .PNG format (Portable Network Graphic) format.
Recommendations:
Pay close attention to the placement of the pre-boot prompt field locations in the default WinMagic-branded logo, so that you will be certain that your background graphics do not interfere with the legibility of those elements.
Start with a photo of the SES default background and use that to advise your graphics team on relative placement of normally-visible elements that must be legible at pre-boot.
Ensure that approximately the lowest 1/10th of the background image you use will be a solid dark color, so that the network icons and language selector option appear clearly against a contrasting dark background. These icons and the selector are always white or very light in color, and will not be easily seen on a light-colored background. Use the SecureDoc original as a guide regarding how tall this dark bottom border needs to be.
If your background logo is predominantly very dark in color, you may need to choose a contrasting light color for prompt text.
NOTE: Only computers with a high resolution monitor (the most common type) will display the customized logo — other monitors will show the default Boot Logon display.
Any customized logos will also not appear on devices using Permanent AutoBoot or HPM (Lenovo's Hardware Password Manager), which do not show the Boot Logon screen.
Implementation/Deployment of a Customized Background Image:
Having created a custom background image file and imported it into an SES profile, that custom background will appear on all NEW SecureDoc installations that reference that Profile, but deployment of the updated profile will not change the background for any already-deployed devices.
To apply a customized background to an already-installed SES-Managed SecureDoc client device or a Stand-Alone device, the background image must be imported into thedevice itself by a user that has logged on using an Administrator key file.
For SES-managed devices, please refer to the SecureDoc Enterprise User Guide, in the section entitled "Customizing Boot Logon", in the subsection entitled "Boot Text and Color". For Stand-Alone devices, please look for the same section in the SecureDoc Stand-Alone User Guide.
