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.
Clear CMOS Headers
(
2-pin CLRMOS2)
(see p. 4, No. 2)
NOTE: CLRMOS2 allows you to clear the data in CMOS automatically when AC power on.
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 CLRMOS2.
(3-pin CLRMOS1)
(see p. 4, No. 4)
NOTE: CLRMOS1 allows you to clear the data in CMOS. To clear and reset the system param-
eters 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 CLRMOS1
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, and time will be cleared only if the CMOS battery is removed.
