If you want to customize the boot screen on the 878, it’s quite simple to do with your favorite image editor.
- Create an image that is 160×128 pixels
- Save/Export it as a bitmap (.bmp) file
- Within the CPS software, select your COM port by clicking Set | Set COM
- Click Tool | Boot Image
- Click Open Image and select your file
- Click Write
That’s it. Here is the basic boot image that I created for my D878UV:

In the File Downloads section of this site, you can download a Blank BMP image to get you started.
Any tips on how you got your fonts so clear? mine appear muddy.

Sorry, I just stumbled on a bunch of messages that went to Spam! I actually went to looked for “Small Fonts” to install. There are some installed by Windows/Mac as well that appear clear. I think one is even called “small font” or something similar. Also, make sure you are not starting with a large image, then resizing. Start with the actual size and then put your text on. Resizing causes a bunch of aliasing.
