MSI Reminds You...
If you don't want to connect to the front audio header, pins 5 & 6, 9 &
10 have to be jumpered in order to have signal output
directed to the rear audio ports. Otherwise, the Line-Out
connector on the back panel will not function.
The motherboard provides the following jumpers for you to set the computer's
function. This section will explain how to change your motherboard's function through
the use of jumpers.
Clear CMOS Jumper: JBAT1
There is a CMOS RAM on board that has a power supply from external battery
to keep the data of system configuration. With the CMOS RAM, the system can
automatically boot OS every time it is turned on. If you want to clear the system
configuration, use the JBAT1 (Clear CMOS Jumper ) to clear data. Follow the instruc-
tions below to clear the data:
MSI Reminds You...
You can clear CMOS by shorting 2-3 pin while the system is off. Then
return to 1-2 pin position. Avoid clearing the CMOS while the system
is on; it will damage the mainboard.
