Apologies for my ignorance. Are you saying that no matter the 
graphical features of the background file, there is no way to display 
such a background using Fn files in CLI or in menu.c32 (or even with 
vesamenu.c32 in text mode)?

My intention was to replace my current "ASCII 24" method used inside 
the Fn files with the second parameter in the Fn statement. If I 
can't, I'll just keep using what I have.

Since the "ASCII 24" method works in CLI (at least in older 
versions), the problem doesn't seem to be some limitation of the text 
mode to display the graphics, but in the possibility to load the same 
background file by means of the aforementioned second optional 
parameter, either in CLI or with menu.c32.

Am I misunderstanding something?

TIA,
Ady.
