如何读取 VESA/VideoBIOS“模式移除表”?

许多有关使宽屏显示器以其原始分辨率在笔记本电脑上工作的网站和文章都提到了视频 BIOS 中称为“模式删除表”的内容,该表专门阻止某些视频模式:

这样的事真的存在吗?该修复对我有用,但我想知道我是否可以阅读、修改或解决此表。但是我在各种 VESA 标准中找不到任何提及。也许它实际上有一些其他更神秘的名字?

Many sites and articles on getting widescreen monitors to work on notebooks in their native resolution mention something called the "Mode Removal Table" in the Video BIOS which specifically prevents certain video modes:

Does such a thing really exist? The fix worked for me but I wanted to find out if I can read, modify, or work around this table. However I can't find any mention of it in the various VESA standards. Perhaps it actually goes by some other more cryptic name?

许多网站和文章”?前几十个结果来自您,而且大多数其余部分来自英特尔文章您提到的或其他人链接到该文章。

您可以随时尝试询问某人尽管他们知道该怎么做。还有另一个线程讨论了它——尽管它也没有公开任何信息,只是简单地提到了它。

目前似乎没有任何已知的方法来读取 GMA 视频 BIOS。您必须转储 BIOS 并将其逆向工程为弄清楚表格在哪里以及如何解释它。不幸的是,即使提取它也很困难,因为似乎没有人对创建自动化工具有足够的兴趣。看起来,你还有更多的倒车要做。 (从技术上讲,由于 GMA 是一个集成图形适配器,因此您需要提取来自系统 BIOS 的视频 BIOS然后提取该表。)

Many sites and articles”? The first couple of dozen results are from you, and most of the rest are from that Intel article you mentioned or other people linking to that article.

You could always try asking someone who talks as though they know how to do it. There's another thread that discusses it—though it too has no information on the table, only a quick mention of it.

There does not seem to be any currently known way to read the GMA video BIOS. You would have to dump the BIOS and reverse-engineer it to figure out where the table is and how to interpret it. Unfortunately, even extracting it is difficult since nobody seems to have had enough interest in creating a tool to automate it. Looks, like you’ve got even more reversing to do. (Techincally, because the GMA is an integrated graphics-adapter, you'll need to extract the video BIOS from the system BIOS, then extract the table.)
