2.5 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.
J u m p e r
Setting
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 5VSB, it requires 2 Amp and higher standby current provided by
power supply.
JR1
(see p.8, No. 29)
JL1
(see p.8, No. 30)
Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear
panel audio connectors can work.
Clear CMOS
(CLRCMOS2, 2-pin jumper)
(see p.8, No. 23)
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 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.
FSB_SEL0
(see p.8, No. 9)
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.
