How to modify boot screen？

[yyds-yyds-yyds]

Hello, I want to ask a question, how to modify the boot screen? I want to change the boot screen, but I don't know how to change it. Can you tell me how to change it?

What exactly do you mean by boot screen. Is it the raspberry pi logo with the progress bar at the bottom.

Yes, it's the logo. How to change it! Sorry, my English is poor and difficult to describe clearly. Thank you for reading patiently.

So the boot image cannot be changed?

It can be changed but UEFI in its current state needs recompiling after you change it in the repository. I have changed mine in this way.

In the RPI_EFI.fd archive itself it seems to have been turned into a binary stream which is mangled with other data inside LogoDxe.efi instead of being an editable .bmp file.

Changing the boot logo requires editing https://github.com/tianocore/edk2-non-osi/blob/master/Platform/RaspberryPi/Drivers/LogoDxe/Logo.bmp as @TheMindVirus pointed out and recompiling your own UEFI Firmware. We do not support trying to edit the logo in the RPI_EFI.fd that is provided from this repository.
