from electrostatic discharge damage, please take care of the following jobs with precautions:
◼Do not remove boards or integrated circuits from their anti-static packaging until you are
ready to install them.
◼Before holding the board or integrated circuit, touch an unpainted portion of the system
unit chassis for a few seconds to discharge static electricity from your body.
◼Wear a grounding wrist strap, available from most electronic component stores, when
handling boards and components.

2.4 Jumper Settings
Pin description
A jumper is a small component consisting of a jumper clip and jumper pins. Install a jumper clip
on two jumper pins to close the jumper pins. Remove the jumper clip from two jumper pins to
open the jumper pins. The following illustration shows how to set up a jumper.
Before applying power to the IMB700 series, make sure all of the jumpers are in factory default
position. Below you can find a summary table of all jumpers and onboard default settings.
Note
Turn off power before changing any default jumper settings.

Note
To identify the first pin of a header or jumper, please refer to the following
information:
⚫Usually, there is a thick line or a triangle near the header or jumper pin 1.
⚫A square pad, which you can find on the back of the motherboard, is usually
used for pin 1.

2.4.1 Temperature Sensor Source Select (JP2)
Use these jumpers (3x1-pin p=2.54mm) to set temperature sensor source to operate
from an external sensor or in onboard mode.
Note
An external sensor can be installed at 1-2.
2.4.2 PCIe x16 slot bifurcation (JP13)
Use these jumpers (3x1-pin p=2.54mm) to set signal for slot location 5 and 6 used as
PCIe x16 slot.
Note
If the setting is 1-2 close, slot location 6 is for PCIe x16 signal and slot
location 5 has no signal.
If the setting is 2-3 close, slot location 6 is PCIe x8 signal and slot location
5 is PCIe x8.
2.4.3 Clear CMOS (JP19)
This jumper (3x1-pin p=2.54mm) allows you to clear the Real Time Clock (RTC) RAM in
CMOS. You can clear the CMOS memory of date, time, and system setup parameters
by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM
data in CMOS, which includes system setup information such as system passwords.
To erase the RTC RAM:
1. Turn OFF the computer and unplug the power cord.
2. Remove the onboard battery.
3. Move the jumper clip from pins 1-2 (default) to pins 2-3. Keep the clip on pins 2-3
for about 5~10 seconds, then move the clip back to pins 1-2.
4. Re-install the battery.
5. Plug the power cord and turn ON the computer.
6. Hold down the <Del> key during the boot process and enter BIOS setup to re-enter
data.
