is placed on the pins, the jumper is "Open".

is placed on these 2 pins.
Jumper
PS2_USB_PW1
(see p.2 item 1)
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by
power supply.
JR1JL1 Jumper
(see p.2 item 24)
Note: If JR1 and JL1 Jumpers are short, both the front panel and the rear panel
audio connectors can work.
Clear CMOS Jumper
(CLRCMOS2)
(see p.2, item 18)
Note: CLRCMOS2 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 2 pins on
CLRCMOS2 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 clear-CMOS action.
