Turn off the computer, unplug the power cord from the power outlet. 2. Remove jumper cap from pins 2 and 3, put it onto pins 1 and 2 to short them. This will clear CMOS data. 3. Return the setting to its original with pins 2 and 3 closed. 4. Plug in the power cord to your computer and turn it on. 5. Go to BIOS Setup to configure new system as described in next chapter. 1 Clear 2 3 Normal 1 2 (Default) 3 CLR_CMOS 19
