Change ACPI setting in AMI BIOS

[ndhunay2]

Hello.

I am using mmtool to modify an existing AMIBOS rom that I downloaded from the manufacturer. I was able to very easily change the BIOS boot picture using the mmtool.

Now I'm trying to make a change to the ACPI settings. In particular here is what I want to change:

Advanced -> ACPI Settings
- "Restore on AC/Power Loss": by default this is off, I'd like it set to "Power On"

So here are my newbie questions:
How do I find out what module that setting is stored in?
Using mmtool I can extract the module, but what's the best way to edit it?
And within the module, how do I know what byte/address I need to modify?

Thank you.
