从 BIOS 闪存映像中提取 SMM (SMI) 处理程序
我可以从主板生产商网站下载更新的 BIOS 固件。将下载“BIOS Flash”映像。
是否可以在 BIOS 映像中找到 SMM (SMI) 处理程序代码?我应该在 BOCHS 下运行 BIOS 才能得到这个吗?
PS SMM是系统管理模式(中断),用于模拟主板上一些未实现的硬件部分。
I can download updated BIOS firmware from motherboard producer site. The image of "BIOS Flash" will be downloaded.
Is it possible to find a SMM (SMI) handlers code in the BIOS image? Should I run the BIOS under BOCHS to get this?
PS SMM is system management mode (interrupt), which is used to simulate some not-implemented-in-hardware parts of motherboard.

可能吧。 ROM 映像中的代码很可能被压缩,这将使查找 SMI 处理程序的任务变得更加困难。事实上,图像中可能有数百 KB 的目标代码,您必须搜索......
Possibly. The code in the ROM image may well be compressed, and that would make the task of finding the SMI handler even more difficult. Then there is the fact that there are likely several hundred KBytes of object code in the image that you'd have to search through...
