Looks like InitializeLogo() [1] is = the entry point to a DXE driver. The INF file for the driver gets parsed an= d used to construct the makefile. The entry point for thee driver is an app= lication and there is some auto generated code that calls all the library c= onstructors and the entry, thus the entry point to the driver can have an a= rbitrary name. 

To build this driver you add the path to the INF fileto your platfor= m DSC file [2] to put it in your ROM you add it to the platform FDF file [2= ].

Hello,

I am trying to display a logo during the uEFI boot.
Found logo.c file. New to this code base.
= I assume I must call:
InitializeLogo (
&= nbsp; IN EFI_HANDLE               ImageH= andle,
  IN EFI_SYSTEM_TABLE        = *SystemTable
  )
&n= bsp;"entrypoint of this module" is in the commenting block.

Where do = I find ImageHandle and SystemTable values???
What am I= missing here?

I = cannot find where InitializeLogo is called, as an example.
When I search for EFI_HANDLE I get a lot of hits.
Any help please. Thanks.
