在Intel 8086上直接通过图形卡绘图 [英] Drawing directly by graphics card on Intel 8086

问题描述

我要在Intel 8086下绘制一些形状，而不使用中断，而是直接访问图形卡.问题是，我不知道如何执行此类操作，因此我什至无法在其中搜索任何内容.我所知道的是，此模式"可在80x25分辨率下工作，并且位于内存中的b800h上.我尝试使用谷歌搜索"8086图形模式"，"8086文本模式"，不间断绘图"等，但没有任何成功.你能告诉我这样的图是怎么称呼的，以便我可以阅读吗?

I am to draw some shapes under Intel 8086 without using interrupts but rather by directly accessing the graphics card. The problem is, I don't know how performing such operations is called so I can't even google anything on it. All I know is that this "mode" works on 80x25 resolution and is located on b800h in the memory. I tried googling "8086 graphics mode", "8086 text mode", "drawing without interrupts" and such but no hits whatsoever. Could you please tell me how such drawing is called so that I can read on it?

推荐答案

访问 VGA视频卡可在此处找到.

如果找不到更详细的信息，则可以始终使用中断调用，然后进行调试并查看其作用.

If you can't find more detailed information, you can always use an interrupt call and then debug and see what it is doing.
