Description
Clear CMOS
(CLRCMOS1, 2-pin jumper)
(see p.2 No. 11)
Note: CLRCMOS1 allows you to clear the data in CMOS. The data in CMOS in-
cludes system setup information such as system password, date, time, and
system setup parameters. To clear and reset the system parameters to de-
fault 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 2 pins
on CLRCMOS1 for 5 seconds.
