audio connectors can work.
Clear CMOS Jumper
(CLRCMOS2)
(see p.2, No. 23)
Note: CLRCMOS2 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 from the power
supply. After waiting for 15 seconds, use a jumper cap to short the Clear
CMOS jumper for 5 seconds. After shorting the Clear CMOS jumper, please
remove the jumper cap. 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.
