Unhiding menues using AMIBCP (changes not saved)

Recommended by Wim's BIOS...

To AMIBCP gurus:

I'm trying to unhide som menues in a HP OEM bios for an MSI OEM board using AMIBCP, but changes I make are not seen when I flash the updated rom-file. Actually, the strange thing is that all sub-menues are allready enabled when I open up the rom-file in AMIBCP, so there must be some additional settings that needs to be made. Or is the code behind the menues not in the rom-file at all?

I'm using the "tool_8_RC1" as posted here on the forum earlier.

Anyone with modding skills that know the inner workings of AMIBCP and could help me out?
