2.5 Jumpers Setup The illustration shows how jumpers are setup. When the jumper cap is placed on pins, the jumper is "Short". If no jumper cap is placed on pins, the jumper is "Open". The illustration shows a 3-pin jumper whose pin1 and pin2 are "Short" when jumper cap is placed on these 2 pins. Jumper Setting PS2_USB_PW1 1_2 2_3 Short pin2, pin3 to enable (see p.10, No. 1) +5V +5VSB +5VSB (standby) for PS/2 or USB wake up events. Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power supply. JR1 JL1 Jumper (see p.10, No. 26) JR1 JL1 Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear panel audio connectors can work. Clear CMOS Jumper (CLRCMOS1) (see p.10, No. 16) 1_2 2_3 Default Clear CMOS Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS includes system setup information such as system password, date, time, and system setup parameters. To clear and reset the system parameters to default setup, please turn off the computer and unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper cap to short pin2 and pin3 on CLRCMOS1 for 5 seconds. However, please do not clear the CMOS right after you update the BIOS. If you need to clear the CMOS when you just finish updating the BIOS, you must boot up the system first, and then shut it down before you do the clearCMOS action. 17
