NVIDIA显卡BIOS编程指南

This document discusses the requirements for standard software access to the NVIDIAÒ family of graphics display processors, which support resolutions, color depths, and frame buffer organizations beyond that of the IBM VGA standard. This guide is written for use by applications and system software programmers, and provides extended interfaces to support enhanced operations such as refresh rate support, monitor type detection, and power management. It serves as a complete reference for the NVIDIA VGA BIOS based on the Release 3 source code. Knowledge of 80x86 assembly language and the VGA hardware may be required to understand the contents of this document. The services in this document may be called from high level languages that provide an interface to the software interrupts of the 80x86 architecture. This document uses “BIOS” and “VGA BIOS” interchangeably to indicate the NVIDIA VGA BIOS.
