Description
PS2_USB_PWR1
Short pin2, pin3 to enable
(see p.8 No. 1)
+5VSB (standby) for PS/2
or USB wake up events.
Note: To 5VSB, it requires 2 Amp and higher standby current provided by
power supply.
JR1 / JL1 Jumper
(see p.8 No. 23)
Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear panel
audio connectors can work.
Clear CMOS
(CLRCMOS0)
(see p.8 No. 12)
Note: CLRCMOS0 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 the Clear CMOS
jumper for 5 seconds. After shorting the Clear CMOS jumper, please remove
the jumper cap. 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.
FSB Select Jumper
(see p.8 No. 31)
Note: The default setting of the FSB Select jumper is shorting pin1 and pin2. Please
keep the default setting for the system’s stability.
