Clear CMOS Jumper
(3-pin CLRCMOS1)
(see p.10, No. 18)
Clear CMOS
Default
CLRCMOS1 allows you to clear the data in CMOS. 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. Please be noted that the password, date, time, user 
default profile, 1394 GUID and MAC address will be cleared only if the 
CMOS battery is removed.
2.7  Jumpers Setup
The illustration shows how jumpers are 
setup. When the jumper cap is placed 
on  the  pins,  the  jumper  is  “Short”.  If 
no  jumper  cap  is  placed  on  the  pins, 
the  jumper  is  “Open”. The  illustration 
shows a 3-pin jumper whose pin1 and 
pin2 are “Short” when a jumper cap is 
placed on these 2 pins.
