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.

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 select +5VSB, it requires 2 Amp and higher standby current provided by power supply.

JR1 / JL1

(see  p.8,  No. 36)

Note:

If the jumpers JL1 and JR1 are short, both the front panel and the rear panel audio

connectors can work.

Clear CMOS

(CLRCMOS2)

(see  p.8,  No. 26)

Note: CLRCMOS2 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_SEL0

FSB_SEL1

(see  p.8,  No. 10)

Note: The setting of the CPU front side bus frequency of this motherboard is by means of the

adjustment of jumper-setting. To perform over clocking, you must set the FSB jumper

according to your AMD CPU before you use the “Manual” option as the FSB setting in

BIOS setup. Please follow the figures above to set the CPU front side bus frequency.
