Swapping Bios settings


I’m trying to swap voltage triggers on a N68-GS4 FX R2.0 so that 0.6V fires 1.55V to the CPU as the bios locks voltages above the default CPU Vcore. I’ve extracted the rom but I have no idea what I should be looking for in MMTool. I have found references to 1.55V in AMIBCP and have gone ahead and fixed a few issues I had with the BIOS but I cant figure out how to swap the two settings.

As far as MMTool is concerned I’ve extracted each module and done a search for the VID codes and numbers but can’t find anything. Any advice would be appreciated.

Thank you.
