Thanks for that but I have already changed the bios boot logo from PIPO to the AUDI logo.
If I boot to windows 10 all I see is the AUDI logo, if I boot to ANDROID I see the AUDI logo for a second and then the PIPO logo for a few seconds and then my bootanimation starts.
I think there must be another logo in the ANDROID bootloader on one of the disk partitions.
By the way if you want to use your Discovery logo on boot, load into a picture editor and rotate it 90 degrees clockwise then save it.
That is how I did mine, I used photoshop.
