Find the documentation on your motherboard, it should tell you the manufacturer and the model number. Also, look through the manual and it should have a page that will show you exactly where the jumper is to clear the CMOS.
To clear the CMOS, make sure that you disconnect the power cord. If you have 2 pins, short the two pins with a jumper for 10 secs then pull the jumper and return it back to the default position.
If you have 3 pins, move the jumper pin from the default position, jumpered 2 and move over to pins 2-3. Wait 10 secs then move back to default position 1-2.
Turn power back on and you should get an error message indicated by beeps to run setup for CMOS. You will then need to make the BIOS settings at this point.
