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.  
2.  
3.  
4.  
Before installing the expansion card, read the documentation that came with  
it and make the necessary hardware settings for the card.  
Remove the system unit cover (if your motherboard is already installed in a  
chassis).  
Remove the bracket opposite the slot that you intend to use. Keep the screw  
for later use.  
Align the card connector with the slot and press firmly until the card is  
completely seated on the slot.  
5.  
6.  
Secure the card to the chassis with the screw you removed earlier.  
Replace the system cover.  
2.5.2  
Configuring an expansion card  
After installing the expansion card, configure 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.  
3.  
Assign an IRQ to the card. Refer to the tables on the next page.  
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. Refer to the table on the next page for details.

Jumper  
Clear RTC RAM (3-pin 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. 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.  
3. Plug the power cord and turn ON the computer.  
4. 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!  
If the steps above do not help, remove the onboard battery and move the  
jumper again to clear the CMOS RTC RAM data. After the CMOS clearance,  
reinstall the battery.

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.  
•
Due to the chipset limitation, AC power off is required prior using C.P.R.  
function. You must turn off and on the power supply or unplug and plug the  
power cord before reboot the system.

4.2  
BIOS setup program  
This motherboard supports a programmable firmware 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.  
The SPI 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, restart the system by pressing  
<Ctrl+Alt+Delete>, or by pressing the reset button on the system chassis. You can  
also restart by turning the system off and then back on. Do this last option only if  
the first two failed.  
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 4.9 Exit Menu.  
•
The BIOS setup screens shown in this section are for reference purposes  
only, and may not exactly match what you see on your screen.

Express Gate’s first screen appears within a few seconds after you power on.  
From here, you can immediately start the web browser or Skype.  
You can also choose to continue booting normally (e.g. to your installed OS such  
as Windows), enter BIOS setup, or power off.  
If you don’t make any selection, Express Gate will automatically exit and boot to  
your normal OS after a certain amount of time. The timer countdown is shown  
on-screen inside the “boot to OS” button. As you move the mouse or type a key,  
the countdown stops and the timer disappears, so you can take your time to make  
a selection.  
The Express Gate Environment  
The very first time you enter the Express Gate environment (by launching either  
web or Skype from the first screen), a first time wizard will guide you through basic  
Express Gate configurations. Basic configurations include language, date and time  
and screen resolution.  
Once inside the Express Gate environment, click on the icons on the LaunchBar,

If Internet does not work in the Express Gate environment, check the following:  
1.  
Open the Configuration Panel.  
2.  
Open Network tool.  
5-36  
Chapter 5: Software support  
3.  
Make the proper network configurations in the Network dialog box.  
Each network interface is enabled immediately when you check the box next  
to it.  
•
If you use a network cable connected to a home router (which is then  
connected to your DSL/cable modem), enable both LAN1 and LAN2.  
Express Gate will automatically use whichever port (LAN1 or LAN2) is  
connected.  
If you plug the network cable into a different port while Express Gate is running  
(e.g. move the cable from LAN1 to LAN2), you may need to restart Express  
Gate for it to detect the change.  
•
•
The most common scenario is for your computer to automatically obtain  
network settings (i.e. DHCP). If this is the case, you don’t need to go into  
“Setup” for any LAN port. If this is not the case, enter “Setup”  
to configure the static IP settings manually.  
If you use wireless, go into “Setup” for the WiFi option. Under the WiFi  
tab, enter the SSID (name of your wireless access point). If your wireless  
access point has security enabled, select the security algorithm from the  
pulldown menu (e.g. WEPAUTO) and enter the password.  
Then enable WiFi to establish the wireless connection.  
•
If you use a network cable connected directly to your DSL/cable modem  
(no router in between), go into “Setup” for xDSL/cable dial-up. This  
method is also referred to as PPPoE. Choose whether the DSL/cable  
modem is connected to your computer’s LAN port. (Refer to  
the drawing in the Network tool to figure out which is LAN1 or LAN2.)  
Then enter the username and password for your dial-up account.  
Then enable xDSL/cable dial-up to establish the PPPoE connection.  
When PPPoE is enabled, the LAN port it uses will automatically be  
unchecked and grayed out.

The Updater can preserve your Express Gate settings and personal data (web  
browser bookmarks, etc.) while doing an update. Use the checkbox “Keep user  
profile” to decide whether the Updater should do so.  
Clearing the user data is useful in the rare case where corrupt settings prevent the  
Express Gate environment from launching properly.  
The first time wizard will run again when you enter the Express Gate  
environment after clearing its settings.

RAID configurations  
The motherboard comes with three RAID controllers that allow you to configure  
SATA / SAS hard disk drives as RAID sets.  
•
•
The NVIDIA® nForce® 790i Ultra SLI™ SATA RAID includes a high  
performance SATA RAID controller that supports RAID 0, 1, 10, and 5 for six  
independent Serial ATA channels.  
Marvell® 88SE6121 eSATA RAID. Enabled by Marvell® 88SE6121 controller,  
the Marvell® RAID supports RAID 0, 1, 10 and 5 sets and extends the  
advantages of software RAID beyond internal hard disk drives to external hard  
disk drives or port-multiplier devices.  
•
Marvell® 88SE6320 SAS RAID. Enabled by Marvell® 88SE6320 controller, the  
Marvell® SAS RAID supports RAID 0 and 1 for two independent SAS channels.  
5.4.1  
RAID definitions  
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 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 10 is data striping and data mirroring combined without parity (redundancy  
data) having to be calculated and written. With the RAID 10* 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.  
If you want to boot the system from a hard disk drive included in a created RAID  
set, copy first the RAID driver from the support DVD to a floppy disk before you  
install an operating system to the selected hard disk drive. Refer to section 5.5  
Creating a RAID driver disk for details.

Chapter 5: Software support  
 
5.4.2  
NVIDIA® RAID configurations  
The motherboard includes a high performance SATA RAID controller integrated in  
the NVIDIA® nForce® 790i Ultra SLI™ chipset. It supports RAID 0, RAID 1, RAID  
10, and RAID 5 for six independent Serial ATA channels.  
Installing Serial ATA (SATA) 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.  
To install the SATA hard disks for a RAID configuration:  
1.  
2.  
3.  
Install the SATA hard disks into the drive bays.  
Connect the SATA signal cables.  
Connect a SATA power cable to the power connector on each drive.  
Refer to the RAID controllers user manual in the motherboard support DVD for  
detailed information on RAID configurations. See section 5.2.5 Manuals menu.  
Setting the BIOS RAID items  
After installing the hard disk drives, make sure to set the necessary RAID items in  
the BIOS before setting your RAID configuration.  
To set the BIOS RAID items:  
1.  
2.  
3.  
4.  
Boot the system and press <Del> during the Power-On Self-Test (POST) to  
enter the BIOS Setup Utility.  
Go to Main > IDE Configuration and enable the nVidia RAID Function item  
in the BIOS. See section 4.3.7 IDE Configuration for details.  
Enable the SATA 1/2/3/4/5/6 drive(s) that you want to configure as RAID. See  
section 4.3.7 IDE Configuration for details.  
Save your changes and Exit Setup.  
Make sure to re-enter your NVRAID settings after the CMOS is cleared;  
otherwise, the system will not recognize your RAID setup.  
For detailed descriptions on the NVIDIA® RAID configuration, refer to the  
NVIDIA RAID User Guide found in your motherboard support DVD.
