Idont see anything wrong about this,

THE PASSWORD YOU ARE TALKING ABBOUNT IS KNOW AS THE POWER ON PASSWORD IF YOU ARE NOT AN EXPERIENCED ENGINEER YOU WILL NOT BE ABLE TO THIS BUT I WILL EXPLAIN THE PROCESS BELOW:

FIRST YOU WILL NEED TO OPEN THE SYSTEM AND REMOVE THE C-MOS BATTERY.THE C-MOS STORES DATA PERMANENTLY ON THE SYSTEM OTHERWISE KNOWN AS THE ROM.
AFTER REMOVING THE C-MOS BATTERY,THEN YOU CHANGE THE JUMPER OF THE C-MOS BATTERY,POWER ON YOUR SYSTEM AND GO TO TO C-MOS SET UP TO CLEAR THE PASSWORD,AFTER WHICH YOU SHUT DOWN,PUT THE BATTERY BACK IN PLACE AND CHANGE THE JUMPER SETTINGS BACK TO WHERE IT WAS BEFORE AND POWER ON THE SYSTEM AGAIN.
NOTE IN SOME MOTHERBOARD,THE C-MOS BATTERY MAY NOT HAVE JUMPER SO WHAT YOU NEED TO DO IN THIS CASE IS JUST REMOVE THE C-MOS BATTERY,GO TO YOUR C-MOS SETUP AND CLEAR THE PASSWORD,SHUT DOWN,PUT THE BATTERY BACK AND POWER ON YOUY SYSTEM,THE PASSWORD WOULD HAVE GONE.
CHEERS.
