Expansion slots
In the future, you may need to install expansion cards. The following
sub-sections describe the slots and the expansion cards that they support.
Make sure to unplug the power cord before adding or removing
expansion cards. Failure to do so may cause you physical injury and
damage motherboard components.
2.5.1
Installing an expansion card
To install an expansion card:
1. Before installing the expansion card, read the documentation that
came with it and make the necessary hardware settings for the card.
2. Remove the system unit cover (if your motherboard is already
installed in a chassis).
3. Remove the bracket opposite the slot that you intend to use. Keep
the screw for later use.
4. Align the card connector with the slot and press firmly until the card is
completely seated on the slot.
5. Secure the card to the chassis with the screw you removed earlier.
6. Replace the system cover.
2.5.2
Configuring an expansion card
After installing the expansion card, configure the it by adjusting the
software settings.
1. Turn on the system and change the necessary BIOS settings, if any.
See Chapter 4 for information on BIOS setup.
2. Assign an IRQ to the card. Refer to the tables on the next page.
3. Install the software drivers for the expansion card.
When using PCI cards on shared slots, ensure that the drivers support
“Share IRQ” or that the cards do not need IRQ assignments; otherwise,
conflicts will arise between the two PCI groups, making the system
unstable and the card inoperable.

Jumpers
1. Clear RTC RAM (CLRTC)
This jumper 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 include
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 cap from pins 1-2 (default) to pins 2-3. Keep the
cap on pins 2-3 for about 5~10 seconds, then move the cap 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.
Except when clearing the RTC RAM, never remove the cap on CLRTC
jumper default position. Removing the cap will cause system boot failure!

M2N-E SLI Clear RTC RAM
You do not need to clear the RTC when the system hangs due to
overclocking. For system failure due to overclocking, use the C.P.R. (CPU
Parameter Recall) feature. Shut down and reboot the system so the BIOS
can automatically reset parameter settings to default values.

Chapter 4: BIOS setup
4.2
BIOS setup program
This motherboard supports a programmable Low-Pin Count (LPC) chip
that you can update using the provided utility described in section “4.1
Managing and updating your BIOS.”
Use the BIOS Setup program when you are installing a motherboard,
reconfiguring your system, or prompted to“Run Setup.” This section
explains how to configure your system using this utility.
Even if you are not prompted to use the Setup program, you can change
the configuration of your computer in the future. For example, you can
enable the security password feature or change the power management
settings. This requires you to reconfigure your system using the BIOS Setup
program so that the computer can recognize these changes and record
them in the CMOS RAM of the LPC chip.
The LPC chip on the motherboard stores the Setup utility. When you start
up the computer, the system provides you with the opportunity to run this
program. Press <Del> during the Power-On Self-Test (POST) to enter the
Setup utility; otherwise, POST continues with its test routines.
If you wish to enter Setup after POST, reboot the system by doing any of
the following procedures:
• Restart using the OS standard shut-down procedure.
• Press <Ctrl>+<Alt>+<Del> simultaneously.
• Press the reset button on the system chassis.
• Press the power button to turn the system off then back on.
Using the power button, reset button, or the <Ctrl>+<Alt>+<Del> keys
to force reset from a running operating system can cause damage to
your data or system. We recommend to always shut-down the system
properly from the operating system.
The Setup program is designed to make it as easy to use as possible. Being
a menu-driven program, it lets you scroll through the various sub-menus
and make your selections from the available options using the navigation
keys.
•
The default BIOS settings for this motherboard apply for most
conditions to ensure optimum performance. If the system becomes
unstable after changing any BIOS settings, load the default settings
to ensure system compatibility and stability. Select the Load Default
Settings item under the Exit Menu. See section “4.8 Exit Menu.”

purposes only, and may not exactly match what you see on your

RAID configurations
The motherboard comes with the NVIDIA® SLI Southbridge RAID controllers
that allow you to configure IDE and Serial ATA hard disk drives as RAID
sets. The motherboard supports the following RAID configurations.
RAID 0 (Data striping) optimizes two identical hard disk drives to read and
write data in parallel, interleaved stacks. Two hard disks perform the same
work as a single drive but at a sustained data transfer rate, double that
of a single disk alone, thus improving data access and storage. Use of two
new identical hard disk drives is required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of
data from one drive to a second drive. If one drive fails, the disk array
management software directs all applications to the surviving drive as
it contains a complete copy of the data in the other drive. This RAID
configuration provides data protection and increases fault tolerance to the
entire system. Use two new drives or use an existing drive and a new drive
for this setup. The new drive must be of the same size or larger than the
existing drive.
RAID 0+1 is data striping and data mirroring combined without parity
(redundancy data) having to be calculated and written. With the RAID
0+1 configuration you get all the benefits of both RAID 0 and RAID 1
configurations. Use four new hard disk drives or use an existing drive and
three new drives for this setup.
RAID 5 stripes both data and parity information across three or more hard
disk drives. Among the advantages of RAID 5 configuration include better
HDD performance, fault tolerance, and higher storage capacity. The RAID 5
configuration is best suited for transaction processing, relational database
applications, enterprise resource planning, and other business systems.
Use a minimum of three identical hard disk drives for this setup.
RAID 1+0 is a striped configuration with each stripe a RAID 1 array of
drives. It combines the features of both RAID 1 and RAID 0. Fault tolerance
is provided through mirroring while adding performance through striping.
This offers higher performance than a RAID 1 configuration but at a much
higher cost. A minimum of four hard disk drives is required for this setup.
JBOD (Spanning) stands for Just a Bunch of Disks and refers to hard disk
drives that are not yet configured as a RAID set. This configuration stores
the same data redundantly on multiple disks that appear as a single disk on
the operating system. Spanning does not deliver any advantage over using
separate disks independently and does not provide fault tolerance or other
RAID performance benefits.
ASUS M2N-E SLI
5-17
If you want to boot the system from a hard disk drive included in a RAID
set, copy first the RAID driver from the support CD to a floppy disk
before you install an operating system to a selected hard disk drive.
Refer to section “5.6 Creating a RAID driver disk” for details.
5.4.1 Installing hard disks
The motherboard supports Ultra DMA /133/100/66 and Serial ATA hard
disk drives. For optimal performance, install identical drives of the same
model and capacity when creating a disk array.
Installing Parallel ATA hard disks
To install IDE hard disks for a RAID configuration:
1. Set the jumpers of each hard disk as Master/Master or Slave/Slave.
2. Install the hard disks into the drive bays.
3. Connect the HDD signal cables.
4. Connect a 4-pin power cable to the power connector on each drive.
Installing Serial ATA (SATA) hard disks
To install the SATA hard disks for a RAID configuration:
1. Install the SATA hard disks into the drive bays.
2. Connect the SATA signal cables.
3. Connect a SATA power cable to the power connector on each drive.
Refer to the RAID controllers user manual in the motherboard support
CD for detailed information on RAID configurations. See section “5.2.4
Manuals menu”.
