Jumper settings
Speaker (J9)
The speaker connector pins are for use with an external speaker. To use the onboard speaker,
close pins 3-4 with a jumper.
CMOS clear (JRTC1)
Instead of pins, the "jumper" in JRTC1 consists of contact pads to prevent the accidental clearing
of CMOS. To clear CMOS, power off the system and remove the AC power cord. Use a metal
object, such as a small screwdriver, to touch both contact pads at the same time and short the
connection.
PCI slots to system management bus speeds (JI

C1)

default setting is open to disable the connection.
