Besa Extended BIOS for Graphics Controllers

摘要

The present invention relates to a VESA BIOS EXTENSION (VBE) for a graphics controller, and receives a predetermined interrupt (interrupt 10 (Hex)) request from a user application program or an operation program (S100). Wow; Receiving the generated interrupt (interrupt 10 (Hex)), determining the type of the requested interrupt, and proceeding to performing the step (S110); If the generated interrupt is an execution interrupt of a basic VGA function, performing a corresponding basic VGA function according to a predetermined register (AH) setting value transmitted (S130); If the generated interrupt is an execution interrupt of the Besa extension BIOS function, performing a corresponding Besa extension BIOS function according to a predetermined register (AH) setting value transmitted (S140); In response to the interrupt, the hardware of the graphics controller performs a corresponding operation (S150).
