I have setup scripts that use the dialog command. They are used to prepare embedded servers. I'd like to display a picture on a edge while a dialog script is running. The problem is, that dialog by design effectively "flushes" what it on the screen and thus removes what was drawn on the framebuffer.
I think there might be a way to display the picture while running a such a script since e.g. some distros show a few tux penguins when booting up while displaying the boot log under them. So something like that would be nice: a picture on the top and a useable dialog under that.
But I don't want that new embedded servers differ from existing ones and I don't want to change existing ones, so e.g. kernel recompilation or installing new software is out of question.
