2.5 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”.
Clear CMOS Jumper
(CLRMOS1)
(see p.1, No. 27)
Short: Clear CMOS
Open: Default
CLRMOS1 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 CLRMOS1 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.
