Jumpers Setup - ASROCK Fatal1ty Z77 Professional-M series User Manual

2.11 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.
Jumper
Clear CMOS Jumper
(CLRCMOS1)
(see p.15, No. 22)
Note: 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 ac-
tion. 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.
The Clear CMOS Switch has the same function as the Clear CMOS
jumper.
