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.
Jumper
PS2_USB_PWR1
(see p.2 No. 2)
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power
supply.
Clear CMOS Jumper
(CLRCMOS1)
(see p.2 No. 32)
Note: CLRCMOS1 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 pin2 and pin3 on CLRCMOS1
for 5 seconds. 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.
FSB1 / FSB2 / FSB3 Jumper
(FSB1, 3-pin jumper, see p.2 No. 33)
(FSB2, 5-pin jumper, see p.2 No. 33)
(FSB3, 5-pin jumper, see p.2 No. 33)
If you want to overclock the memory module you adopt to DDR2 1200 on this
motherboard, you need to adjust the jumpers. Please short pin2, pin3 for FSB1
jumper, pin4, pin5 for FSB2 jumper, and pin4, pin5 for FSB3 jumper. Otherwise, the
memory module may not work properly on this motherboard. Please refer to below
jumper settings.
