4.3 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 Jumper
(2-pin CLRMOS2)
(see p.16, No. 25)
Note: CLRMOS2 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 CLRMOS2 for 3 seconds. Please remember to re-
move 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.
Clear CMOS Jumper
(CLRMOS1)
(see p.16, No. 19)
Note: CLRMOS1 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 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, time, user default profile and MAC
address will be cleared only if the CMOS battery is removed.
