Jumpers Setup - ASROCK P4I45GL User Manual

2.7 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
PS2_USB_PWR1
(see p.8/p.9 item 2)
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by
power supply.
JR1
(see p.8/p.9 item 23)
JL1
(see p.8/p.9 item 22)
Note: When you connect speakers in back panel and front panel at the same time,
1. If the jumpers JL1 and JR1 are short (see fig. 1), both front panel and
rear panel audio connectors can work.
2. If both jumper caps on JL1 and JR1 are removed (see fig. 2), only front
panel audio works.
However, it requires your front panel to support the function.
CLRCMOS0
(see p.8/p.9 item 15)
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, then use a jumper
cap to short the pins on CLRCMOS0 for 3 seconds. Please remember to
remove the jumper cap after clearing the CMOS.
