ABSTRACT:
The subject invention relates to a Universal Graphics Adapter (UGA) that is a hardware-independent design that encapsulates and abstracts low-level graphics hardware in a standard manner through firmware. UGA is a firmware standard, intended to wrap existing or planned hardware, including VGA. UGA does not require the use of real-mode assembly language, direct hardware register, or frame buffer access to program, thus providing advantages over conventional systems. UGA supports basic drawing operations, continuous display modes, and power management. As a firmware-based standard, UGA facilitates updating a system to support both evolving and new hardware features. UGA includes the capability to determine ranges of output display capabilities for multiple devices and determine an overlap in capabilities of the multiple devices.
