CoreModule 420 Reference Manual 53
Splash Screen Customization
The CoreModule 420 BIOS supports a graphical splash screen, which can be customized by the user and
displayed on screen when enabled through the BIOS Setup Utility. The graphical image can be a
company logo or any custom image the user wants to display during the boot process. The custom
image can be displayed as the first image displayed on screen during the boot process and remain there,
depending on the options selected in BIOS Setup, while the OS boots.

Splash Screen Image Requirements

The user’s image may be customized with any bitmap software editing tool, but must be converted into
an acceptable format with the tools (files and utilities) provided by Ampro. If the custom image is not
converted with the utilities provided, then the image will not display properly when this feature is
selected in BIOS Setup.
NOTE Do not use other splash screen conversion tools, as these will render an
image that is not compatible with the CoreModule 420 BIOS.
The splash screen image supported by the CoreModule 420 BIOS should be:
•Bitmap image
•Exactly 640x480 pixels
•Exactly 16 colors
•A converted file size of not greater than 55kB

Converting the Splash Screen File

The following files are provided by Ampro on the CoreModule 420 Doc & SW CD-ROM and are
required for converting a custom splash screen file. Refer to the Miscellaneous Source Code Examples
subdirectory under the Support Software directory on the CD-ROM for the utilities and examples of how
to load a customized image in the cm420\software\examples\splash directory.
• splash.bmp • resplash.com
• convert.exe • cm420.bin
• convert.idf
The process of converting and loading a custom image onto the CoreModule 420 involves the following
sequence of events:
•Prepare directory for conversion (create directory and copy files into it)
•Obtain the CoreModule 420 BIOS binary
•Prepare the custom image file
•Convert the image to an acceptable BIOS format
•Merge the image with BIOS binary to create new BIOS binary
•Load the new BIOS binary onto the CoreModule 420 board
NOTE You can use any Windows PC to convert the custom image, but your
PC must have an internet browser to access, view, and make selections
in the main menu of the CoreModule 420 Doc & SW CD-ROM.
For example: Microsoft Internet Explorer 4.x, or greater, Netscape
Navigator version 4.x, or greater , or the equivalent.
