摘要
主要介绍 VESA 扩充 SVGA 显示标准及利用该标准进行编程的一般方法,说明在软件编制过程中如何获得某一特定显示卡的信息,如该卡可设定的模式,显示缓存映射关系等,利用这些信息,编程人员可以不需要关心显示硬件系统来进行编程。
This paper describes how to extend SVGA industrial standards using VESA, presents a general programming by means of the extended standards.The program shows how to get information of a certain video adapter such as the video modes that may be set,the video buffer mapping,etc.Using this information,programmer can make program without understanding video hardware system.
