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 Description
PS2_USB_PWR1 Short pin2, pin3 to enable
(see p.2 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.
Clear CMOS
(CLRCMOS1, 2-pin jumper)
(see p.2 No. 8)
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 2 pins on
CLRCMOS1 for 5 seconds.

EUP LAN / EUP Audio Jumper
(EUP_LAN1, 3-pin jumper, see p.2 No. 22)
(EUP_AUDIO1, 3-pin jumper, see p.2 No. 20)
Note: EUP_LAN and EUP_AUDIO jumper design decreases the power consumption
of this motherboard to meet EuP standard. With an ASRock EuP ready
motherboard and a power supply that the 5VSB power efficiency is higher
than 50% under 100mA current consumption, your system is able to submit
EuP standard. The default setting (short pin1 and pin2) is EuP enabled. If you
want to disable this power saving function, you may short pin2 and pin3.
Please be noticed that when EUP_LAN jumper is set to enabled, the
Wake-On-LAN function under S3 (Suspend to RAM), S4 (Suspend to Disk),
and S5 (Soft Off) will be disabled.
Default (Enable EuP)
(Disable EuP)
