Creating a Splash Screen
Use a bitmap file to create a customized splash screens for the mobile computer. Use Image Update with a bitmap 
file, rather than a package file, to update the splash screen.
To create a custom splash screen:
1. Create a .bmp file using a graphic program with the following specifications:
•
Size: 240 x 296.
•
Colors: 8 bits per pixel (256 colors) for color displays.
2. Modify the bitmap file and save.
To load the splash screen on the mobile computer:
1. Create a text file named pkgs.lst which contains the name of the bmp file. For example, mysplash.bmp.
2. Copy the bmp file and the pkgs.lst file to one of the following:
•
SD card root directory
•
mobile computer’s \temp directory
•
mobile computer’s \Windows directory.
3. If using an SD card, insert the SD card into the mobile computer.
4. Perform a cold boot.
5. Press the trigger or side scan button for 5 seconds while booting to invoke the Update Loader and install the 
splash screen.
NOTE When initiating an update via a boot sequence, the update loader looks for updates first on the root of an 
installed SD card and then in the \temp folder on the mobile computer’s persistent storage volume. A 
response file, pkgs.lst, indicates which files to update. In most cases, Symbol provides this pkgs.lst file with 
the update and you should only modify it when updating a splash screen partition. See Creating a Splash 
Screen for more information.
