PS2_USB_PWR1
(see p.2 item 1)
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power
supply.
JR1 / JL1 Jumpers
(see p.2 item 23)
Note: If JR1 and JL1 Jumpers are short, both the front panel and the rear panel audio
connectors can work.
Clear CMOS Jumper
(CLRCMOS2)
(see p.2 item 22)
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.
J1 Jumper
(FID0, FID1, FID2, FID3, FID4)
(see p.2 item 29)
Note: The set of J1 Jumper allows users to adjust the multiplier of CPU. See page 14 of User
Manual in the Support CD for details. However, the system will work well without the
adjustment of multiplier. You do not have to adjust the multiplier for normal usage.
