US Patent 10592256 Early boot display system

A secondary processing system that is coupled to a primary processing system and a display system accesses a first memory system to load initial boot instructions and a video interpreter binary during a boot operation. The secondary processing system initializes the display controller included in the display system to provide a first graphical user interface for display on the display screen using the video interpreter binary and executes the initial boot instructions. The secondary processing system then detects a first interrupt event during the execution of the initial boot instructions and, in response, triggers the video interpreter binary to update the first graphical user interface displayed on the display screen to provide a second graphical user interface for display on the display screen.
