I currently have the same board with the bios password I don't have. And I am looking for a solution. I have seen that the board has 3 winbond chips and it really makes me doubt which one I have to replace or remove.

if the problem is only the Administrator password dump the 16Mb chip only and use RCUnlocker to edit the file and remove the password.
