IrDA Infrared Module Header: JIR1
The connector allows you to connect to IrDA Infrared module. You
must configure the setting through the BIOS setup to use the IR function.
JIR1 is compliant with Intel

Chassis Intrusion Switch Connector: JCI1
This connector is connected to a 2-pin chassis switch. If the chassis is
opened, the switch will be short. The system will record this status and show
a warning message on the screen. To clear the warning, you must enter the
BIOS utility and clear the record.

 MS-6712 ATX Mainboard
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 instructions below to clear the data:
Jumpers
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.

Hardware Setup
Slots
AGP (Accelerated Graphics Port) Slot
The AGP slot allows you to insert the AGP graphics card.  AGP is an
interface specification designed for the throughput demands of 3D graphics.
It introduces a 66MHz, 32-bit channel for the graphics controller to directly
access main memory. The mainboard supports 4x/8x 1.5V AGP card.
PCI (Peripheral Component Interconnect) Slots
The PCI slots allow you to insert the expansion cards to meet your needs.
When adding or removing expansion cards, make sure that you unplug the
power supply first. Meanwhile, read the documentation for the expansion card
to make any necessary hardware or software settings for the expansion card,
such as jumpers, switches or BIOS configuration.
CNR (Communication Network Riser) Slot
The CNR slot allows you to insert the CNR expansion cards. CNR is a
specially designed network, audio, or modem riser card for ATX family
motherboards. Its main processing is done through software and controlled
by the motherboard’s chipset.The motherboard provides one AGP slot, six 32-bit PCI bus slots, and
one CNR slot.

PCI Interrupt Request Routing
The IRQ, acronym of interrupt request line and pronounced I-R-Q, are
hardware lines over which devices can send interrupt signals to the
microprocessor.
The PCI IRQ pins are typically connected to the PCI bus INT A# ~ INT
D# pins as follows:
Order 1 Order 2 Order 3 Order 4
PCI Slot 1 INT A# INT B# INT C# INT D#
PCI Slot 2 INT B# INT C# INT D# INT A#
PCI Slot 3 INT C# INT D# INT A# INT B#
PCI Slot 4 INT D# INT A# INT B# INT C#
PCI Slot 5 INT B# INT C# INT D# INT A#
PCI Slot 6 INT C# INT D# INT A# INT B#

BIOS Setup
This chapter provides information on the BIOS Setup program
and allows you to configure  the system for optimum use.
You may need to run the Setup program when:
” An error message appears on the screen during the system
booting up, and requests you to run SETUP.
” You want to change the default settings for customized
features.

Entering Setup
Power on the computer and the system will start POST (Power On Self
Test) process.  When the message below appears on the screen, press 
key to enter Setup.
DEL:Setup F11:Boot Menu F12:Network boot TAB:Logo
If the message disappears before you respond and you still wish to enter
Setup, restart the system by turning it OFF and On or pressing the RESET
button.  You may also restart the system by simultaneously pressing ,
, and  keys.
Selecting the First Boot Device
You are allowed to select the 1st boot device without entering the BIOS
setup utility by pressing .  When the same message as listed above
appears on the screen, press  to trigger the boot menu.
The POST messages might pass by too quickly for you to respond in
time.  If so, restart the system and press  after around 2 or 3 seconds to
activate the boot menu similar to the following.
The boot menu will list all the bootable devices. Select the one you want
to boot from by using arrow keys and then pressing .  The system will
boot from the selected device.  The selection will not make changes to the
settings in the BIOS setup utility, so next time when you power on the system,
it will still use the original first boot device to boot up.

lected setup category is displayed at the bottom of the screen.
Default Settings
The BIOS setup program contains two kinds of default settings: the BIOS
Setup and High Performance defaults.  BIOS Setup defaults provide stable
performance settings for all devices and the system, while High Performance
defaults provide the best system performance but may affect the system
stability.
