ASRock IMB-196 [14/42] Jumpers setup

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.

Jumper Setting Description

Clear CMOS Jumper

(3-pin CLRCMOS1)

(see p.8, No. 33)

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 nish updating the BIOS, you must boot up

the system rst, and then shut it down before you do the clear-CMOS action.

Please be noted that the password, date, time, user default prole and MAC

address will be cleared only if the CMOS battery is removed.
