Hello almastriste,
Do you want to compare the two BIOS images directly to see if they are identical? Then, you would need to use a hex editor. I personally use HxD. It is free and works well. Open the program, press Ctrl+K on the keyboard and point the program to the two files you want to compare and it will give you a notification if they are identical.
If you want to compare two BIOS images to see how they differ, you will need to complete a few steps using three programs. The first step is to extract each BIOS file. Use
PhoenixTool to extract Phoenix/Insyde/Dell BIOS images. You will need different programs for other BIOS types. The second step is to compare the two DUMP directories that PhoenixTool (or another program) creates. You can do this with WinMerge. It can compare two directories and tell you which files are identical and different compared to their counterparts. The third step is to use the hex editor to compare any files that WinMerge says are different.
If you need any help with these steps, just leave a reply here.
