Extracting SMM (SMI) handlers from BIOS flash image

1.7k Views Asked by At

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.

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...
