ASRock motherboard is equipped with pin headers with obvious colors which indicate you to recognize the crucial headers more easily. Please refer to below illustrations for the pin defi nition of onboard headers. If you want to have more information
about the usage of these headers, please refer to “Jumpers Setup“ and “Onboard
Headers and Connectors“ for details.

1.4 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 Description
Clear CMOS Jumper
(CLRCMOS1)
(see p.2, No. 19)
Note: CLRCMOS1 allows you to clear the data in CMOS. 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 fi nish updating the BIOS, you must boot
up the system fi rst, and then shut it down before you do the clear-CMOS ac-
tion. Please be noted that the password, date, time, user default profi le, 1394
GUID and MAC address will be cleared only if the CMOS battery is removed.
Clear CMOSDefault
If you clear the CMOS, the case open may be detected. Please adjust
the BIOS option “Clear Status” to clear the record of previous chassis
intrusion status.

(see p.2 No. 14)
several system front panel
functions.
Connect the power switch, reset switch and system status indicator
on the chassis to this header according to the pin assignments below.
Note the positive and negative pins before connecting the cables.
PWRBTN (Power Switch):
Connect to the power switch on the chassis front panel. You may confi gure the way to turn off your system using the power switch.
RESET (Reset Switch):
Connect to the reset switch on the chassis front panel. Press the reset
switch to restart the computer if the computer freezes and fails to perform a normal restart.
PLED (System Power LED):
Connect to the power status indicator on the chassis front panel. The
LED is on when the system is operating. The LED keeps blinking
when the sys-tem is in S1 sleep state. The LED is off when the system
is in S3/S4 sleep state or powered off (S5).

HDLED (Hard Drive Activity LED):
Connect to the hard drive activity LED on the chassis front panel. The
LED is on when the hard drive is reading or writing data.
The front panel design may differ by chassis. A front panel module
mainly consists of power switch, reset switch, power LED, hard drive
activity LED, speaker and etc. When connecting your chassis front
panel module to this header, make sure the wire assignments and the
pin assign-ments are matched correctly.
Chassis Speaker Header Please connect the chassis
