2.6 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.

(see p.10/p.11, No. 1)

+5VSB (standby) for PS/2 or

USB wake up events.

JL1

(see  p.10/p.11, No. 23)

Note: If the jumpers JL1 and JR1 are short (see the figure above), both the front

panel and the rear panel audio connectors can work.

Clear CMOS

(CLRCMOS0, 2-pin Jumper)

(see  p.10/p.11, No. 18)

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 rem ember to

remove the jumper cap after clearing the CMOS. 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.
