Jumper Settings
Explanation of
Jumpers
To modify the operation of the moth-
erboard, jumpers can be used to
choose between optional settings.
Jumpers create shorts between two
pins to change the function of the
connector. Pin 1 is identified with a
square solder pad on the printed cir-
cuit board.
See the motherboard
layout pages for jumper locations.
CMOS Clear
Refer to Table 2-16 for instruc-
tions on how to clear CMOS. Al-
ways remove the AC power cord
from the system before clearing
CMOS.
Note: For an ATX power supply, you must
completely shut down the system, remove the
AC power cord, then use JBT1 to clear CMOS.
Replace JBT1 back to the pin 1-2 position be-
fore powering up the system again. Do not
use the PW_ON connector to clear CMOS.
