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.

Setting

FSB_SEL0

(see p.7 item 9)

FSB_SEL1

(see p.7 item 10)

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

adjustment of jumper-setting. You must set the FSB jumper according to your AMD CPU

before you use the “Manual” option as the FSB setting in BIOS setup to perform over

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

 PS2_USB_PWR1

Short pin2, pin3 to enable

(see p.7 item 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

(see p.7 item 28)

JL1

(see p.7 item 27)

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

can work.

Clear CMOS Jumper

(CLRCMOS2)

(see p.7 item 17)

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, then use a jumper cap to short the pins on CLRCMOS2 for 3

seconds. Please remember 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.
