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		Setting	Description
FSB1			“NORMAL” (short pin1, pin2)
(see p.9 item 9)			is the default setting for the
1_2	1_2	2_3	FSB jumper. “1066” (short
			pin2, pin3) is the setting for
FSB 533MHz	FSB 800MHz FSB 1066MHz		the over clocking of CPU
			frequency.
PS2_USB_PWR1	1_2	2_3	Short pin2, pin3 to enable
			+5VSB (standby) for PS/2
(see p.9 No. 1)
	+5V	+5VSB	or USB wake up events.

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

JR1 JL1

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

Clear CMOS (CLRCMOS0, 2-pin jumper)

(see p.9 No. 13) 2-pin jumper

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 from the power supply. After waiting for 15 seconds, use a jumper cap to short 2 pins on CLRCMOS0 for 5 seconds.
