I just finished adding a boot logo to my carputer, I'll share it in case anyone comes along with a similar setup who wants a similar logo ;-).
Here is what it looks like on my screen. The image I'm showing is 800x480, which is the native resolution of my LCD. The actual image I put in the flash is one created at 800x480 natively, then resized to 640x480 so that when the LCD stretches it to fit the display, it'll have the correct dimensions. Make sense?
The motherboard is a VIA EPIA MII 12000. The BIOS version is 1.35. No changes have been made to the BIN other than adding the boot logo. This works on my setup --
but the risk of flashing your own BIOS with this file is entirely your own risk.
That said ... the file is
here.
