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
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
(see p.7 item 1)
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.
