80 Reference Manual LittleBoard 550
Use the following steps to convert and load your custom image onto the LittleBoard 550.
1. Copy the files from the LB550\software\examples\splash directory on the CD-ROM to a new
directory (conversion directory) on your PC.
This new conversion directory is where you intend to do the conversion and save the file.
2. Remove the read-only attributes from all the files as part of the file copying process.
3. Copy the LittleBoard 550 BIOS binary file (lb550.bin) to the new conversion directory on your
PC where the other files and utilities are located.
If this file is not on the LittleBoard 550 Doc & SW CD-ROM, you will have to obtain it from
Ampro.
NOTE Ampro recommends keeping a copy of this original lb550.bin file,
just in case you encounter problems with your new file or have
difficulty updating the BIOS with the new image.
4. Prepare your custom image file with any Windows bitmap software editing tool.
♦ For example, Corel Photo-Paint, Adobe Photoshop, or the Windows Paint program provided
with Windows. You can insert a desired graphic image, logo, text, etc. into the file.
♦ The custom image must be a bitmap image in .bmp format at 640x480 pixels and it must be
16 colors. The file should be about 153,718 bytes. Refer to the example file splash.bmp.
5. Save your custom image file as splash.bmp at 640x480 pixels by 16 colors.
♦ If your custom image file is not approximately 153,718 bytes in size it is probably not in the
right format or is too complex to be used in the BIOS. You will have to edit it down in size
until you have reached an acceptable file size.
♦ If you are doubtful about the conversion process, due to the file size, Ampro recommends
making a copy of your new splash.bmp, so that you can edit it later if the conversion does not
yield a small enough file. Otherwise, you may have to re-create your custom image before
you can edit it down to an acceptable file size.
6. If your custom image file is not on the conversion PC, copy the new splash.bmp file to the
conversion directory.
7. Run the following command from DOS, or a Windows DOS pop-up screen to convert your new
splash.bmp file.
C:\splash>convert convert.idf
This conversion should yield a splash.rle file of approximately 55kB in size or less, depending on
the complexity of your image.
8. If the splash.rle file size is greater than 55kB, go back to the unconverted image file and edit the file.
You may reduce the file size of the converted image (splash.rle) by reducing the image’s
complexity.
9. Run the following command to merge the converted image with the BIOS binary file.
C:\splash>resplash lb550.bin splash.rle lb550n.bin
This creates a new BIOS named lb550n.bin, which has the new splash image. This new BIOS is
ready to be loaded onto the LittleBoard 550.
10. Copy the files update.bat, aflash.exe, and lb550n.bin to a DOS boot floppy.
11. Boot the LittleBoard 550 from the floppy and run update.bat.
12. Cycle the power to the LittleBoard 550 and enter BIOS Setup to enable the splash screen.
