System and method for UEFI advanced graphics utilizing a graphics processing unit
A central processing unit executes a graphics accelerated operation during a pre-boot basic input/output system (BIOS). The central processing unit initializes multiple protocol scheduler circuitry during an early phase of the pre-boot BIOS. The multiple protocol scheduler circuitry initializes host memory pages, and creates one or more bit block transfer tasklets during the pre-boot BIOS. A graphics processing core executes one of the bit block transfer tasklets, and renders a graphical user interface element for display during the pre-boot BIOS.
