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.7 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/JL1 Jumpers
(see p.7 No. 22)
Note: If the jumpers JL1 and JR1 are short, both the front panel and the rear panel
audio connectors can work.
Clear CMOS
(CLRCMOS1, 2 solder points)
(see p.7 No. 15 )
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, then short the solder
points for more than 3 seconds by using metal material, e.g., a paper clip. 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.
