Open: Default
CLRMOS1 allows you to clear the data in CMOS. e data in CMOS includes
system setup information such as system password, date, time, and system setup
parameters. ere are two ways for you to clear and reset the system parameters
to the default setup. Please turn o the computer and unplug the power cord, then
you may either short the solder points on CLRMOS1 by using metal material,
e.g., a paper clip for 3 seconds; or you may use a jumper cap to short the pin on
CLRMOS1 for 3 seconds. Please remember to remove the paper clip or the jumper
cap aer clearing the CMOS.
2-pin Jumper
*e jumper cap is not provided.
If you clear the CMOS, the case open may be detected. Please adjust the BIOS option
“Clear Status” to clear the record of previous chassis intrusion status.
