BY USING MOTHERBOARD JUMPER
ALMOST ALL MOTHERBOARD CONTAIN A JUMPER THAR CAN CLEAR ALL CMOS SETTINGS ALONG WITH THE BIOS PASSWORD.THE LOCATION OF THIS JUMPER VARIES DEPENDING UPON THE MOTHERBOARD BRAND.YOU SHOULD READ YOUR MOTHERBOARD MANUAL TO CHECK ITS LOCATION.IF YOU DON'T HAVE THE MANUAL THEN LOOK FOR THE JUMPER NEAR THE CMOS BATTERY.MOST OF THE MANUFACTURER LABEL THE JUMPER AS CLR.CLEAR,CLEAR CMOS ETC.
WHEN YOU FIND THE JUMPER ,LOOK CAREFULLY WILL BE 3 PINS AND THE JUMPER WILL BE JOINING THE CENTER PIN TO EITHER LEFT OR RIGHT PIN.WHAT YOU NEED TO DO, IS REMOVE THE JUMPER AND JOIN THE CENTER PIN TO THE OPPOSITE PIN.
E.G IF THE JUMPER JOINS CENTER PIN TO LEFT PIN,THEN REMOVE IT AND JOIN CENTER PIN TO RIGHT PIN.NOW WAIT FOR A FEW SECONDS AND THEN AGAIN REMOVE THE JUMPER AND JOIN THE CENTER PIN TO LEFT PIN.
