Perhaps search for "BGRT"-related components. There are tools to modify the logo in binaries at run-time. Eg:
https://firmwaresecurity.com/2020/02/10/bgrtinjector-customize-boot-logo-without-modifying-uefi/ https://firmwaresecurity.com/2016/05/21/hackbgrt-changes-windows-boot-logo-on-uefi-systems/ https://blog.fpmurphy.com/2015/07/access-bsrt-information-and-boot-logo-from-uefi-shell.html But I don't know how to change the logo in sources at design-time. I'm not aware of any Tianocore docs on the subject, the only OEM-focused info on topic I know of is Windows-centric: https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/boot-screen-components HTH, Lee PS: FWIW, one of my blog's most commonly-accessed articles are the above ones, end-users wanting to customize their logo. Maybe this is a sign that end-users want to customize their HW/FW/OS boot logos: perhaps OEMs/IHVs might want to add a feature to their product to let end-users easily change this, eg, from a BIOS Menu.
