1-2 Safe Notice

IWILL assumes the reader of this document is an experienced systems integrator. Please read
our instruction while you are installing the system.

General Safety Precautions

 Keep the area around the Server clean and free of clutter.

 Servers weigh a lot. When lifting the system, two people should lift slowly from opposite ends with their feet

spread out to distribute the weight. Always keep your back straight and lift with your legs.

 Place the chassis top cover and any system components that have been removed away from the system or

on a table so that they won’t accidentally be stepped on.

 While working on the system, do not wear loose items such as neckties and unbuttoned shirtsleeves. They

can come into contact with electrical circuits or get pulled into a cooling fan.

 Remove any jewelry or metal objects from your body, which are excellent metal conductors and can create

short circuits and harm you if they come into contact with printed circuit boards or areas where power is
present.

ESD Precautions

Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with
each other. An electrical discharge is created to neutralize this difference, which can damage electronic components
and printed circuit boards. The following measures are generally sufficient to neutralize this difference before
contact is made to protect your equipment from ESD:

 Use a grounded wrist strap designed to prevent static discharge.

 Keep all components and printed circuit boards (PCBs) in their antistatic bags until ready for use.

 Touch a grounded metal object before removing the board from the antistatic bag.

 Do not let components or PCBs come into contact with your clothing, which may retain a charge even if you

are wearing a wrist strap.

 Handle a board by its edges only; do not touch its components, peripheral chips, memory modules or

contacts.

 When handling chips or modules, avoid touching their pins.

 Put the motherboard and peripherals back into their antistatic bags when not in use.

8

 For grounding purposes, make sure your computer chassis provides excellent conductivity between the

power supply, the case, the mounting fasteners and the motherboard.

 After accessing the inside of the system, close the system back up and secure it to the rack unit with the

retention screws after ensuring that all connections have been made.

Operating Precautions

 Check package contents

 Missing or damaging accessories

Please contact your vendor immediately
 Motherboard damage

Please contact your vendor immediately

RAID Type Description

Striping arrays use multiple disks to form a larger virtual disk. While Striping is discussed as a

RAID 0 (Striping)

RAID Set type, it is does not provide any fault tolerance.
Disk mirroring creates an identical twin for a selected disk by having the data simultaneously

RAID 1(Mirroring)

written to two disks. This redundancy provides instantaneous protection from a single disk
failure.
RAID 10 combines the features of both RAID 0 and RAID 1. Performance is provided through

RAID 10

the use of Striping (RAID 0), while adding the fault tolerance of Mirroring (RAID 1). The
implementation of RAID 10 requires four drives.

1GB, and 2GB combinations. Total memory size for one mainboard is between 128MB and 16GB.

IMPORTANT

The system mainboard has strict memory type and timing requirements. Before you purchase DDR (Double Data
Rate) memory for using in the system mainboard, you should contact your local reseller for a recommend list of
system memory that has been validated on this system.

IMPORTANT

To take advantage of the 128-bit interface, you must install DIMMs in pairs of two (2). DIMM slots DIMM0 and
DIMM1 are paired, and slots DIMM2 and DIMM3 are paired. If you are only installing two DIMMS into a Memory
Bank, it is recommended that you install them in slots DIMM0 and DIMM1 to get the full bandwidth.

3-4.1 Memory Installation Procedures

1. Locate the DIMM modules

2. Make sure the DIMM’s pins are facing down, and check that the pin arrangement on the memory module
resembles the one pictured below.

IMPORTANT

Always populate H0 DIMM socket before installing memory modules in the H1 DIMM sockets.

35

3. Insert the module into the DIMM socket and press down evenly on both ends firmly until the DIMM module is
securely in place. (The tabs of the DIMM socket will close-up to hold the DIMM in place when the DIMM is
properly installed into the socket.)

36

3-5 EPS Power Supply

These 24-pin connectors connect the server board to the EPS power supply. Find the proper orientation and push
down firmly to make sure that the pins are aligned. The 8-pin connector provides a dedicated power supply for the
CPUs.

IMPORTANT

IWILL® always recommends our customers use EPS12V Power supplies. For any power damaged, please contact
your retailer or IWILL

®

technicians.

Warning

There are two 24 pin connectors. Please choose either one to install. DON’T plug into both connectors at the same
time.

37

3-6 CPU/ System Fan Connectors

There are night 3-pin fan connectors in the Mainboard. Two fans are used for CPU1 and CPU0; seven fans are for
system and back. These connectors support cooling fans of 500mA (6W) or less. All fan drive current minimum are
must over 1.5V. Depending on the fan manufacturer, the wiring and plug may be different. Connect the fan’s plug to
the Mainboard with respect to the polarity of the fan connector.

Warning

The CPU and motherboard will overheat if there is not enough airflow across the CPU and onboard heatsink.
Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. T hese are NOT
jumpers; DO NOT place jumper caps over these pins.

38

3-7 Install Expansion Cards

Warning

Please power off your power supply completely when adding removing any expansion card or other system
components. Failure to do so may cause severe damage to both your motherboard and expansion card.

3-7.1 Expansion Card Installation Procedure

Read the documentation for your expansion card and make any necessary hardware or software setting changes
such any jumper configuration.

1. Remove the bracket plate on the slot you intend to use. Keep the bracket for possible future use.

2. Carefully align the card's connectors and press with the riser card firmly.

3. Secure the card on the slot with the screw you removed above.

3-7.2 Assigning IRQs for PCI Expansion Cards

An IRQ number is automatically assigned to PCI expansion cards. In the PCI bus design, the BIOS automatically
assigns an IRQ to a PCI slot that contains a card requiring an IRQ. To install a PCI card, you need t o set the INT
(interrupt) assignment. Since all the PCI slots on this motherboard use an INTA #, set the jumpers on your PCI cards
to INTA.

39

3-7.3 HTX Pro Adapter Card

DK8-HTX equips with a HTX-PRO interface. This expansion will fully support the PathScale InfiniPath™ HTX™
Adapter Card. About the information of PathScale InfiniPath™ HTX™ Adapter Card, you could check on PathScal e
website:

http://www.pathscale.com/. Or, you can contact with your local vendors.

40

3-8 Powering on your System

Follow these instructions to power on the computer after you have installed the Mainboard and all system devices.

1. Be sure that all switches are off (in some systems, Off is marked by “O”). After double-checking all jumper

settings and connections, close the system chassis cover.

2. Connect the power cord to the power cord connector located on the power supply at the back of your

system chassis and plug the power cord into a power outlet that is equipped with a surge protector.

3. Turn on your devices in the following order:

 Monitor

 System power

4. For power supplies, you need to switch On the power supply, then press the Power switch on the front of

the chassis.

5. The power LED on the front panel of the system case will light up. For power supplies, the system LED will

light up when the power switch is pressed. The monitor LED may light up after the system’s LED if it
complies with “Green” standards or if it has a power standby feature. The system will first run its “power-on”
tests. While the tests are running, additional messages will appear on the screen.

6. If you do not see anything on the screen within 30 seconds from the time you turn on the power, the system

may have failed a power-on test. Re-check your jumper settings and connections. Contact your
retailer/dealer for assistance if everything else fails.

7. During power-on, hold down <DEL> to enter BIOS setup. Follow the instructions in BIOS for further setup

information.

Chapter 4 BIOS Setup

This chapter discusses the AMI BIOS Setup program built into the ROM BIOS. The Setup
program allows users modifying the basic system configurations according to their
requirements. This special information is then stored in battery-backed RAM so that it retains
the Setup information when the power is turned off.

The AMI BIOS installed in your computer system's ROM (Read Only Memory) is a custom
version of an industry standard BIOS. The BIOS provides critical low-level support for standard
devices such as disk drives and serial ports.

The AMI BIOS has been customized by adding important, but non-standard, features such as
password protection as well as special support for detailed fine-tuning of the chipset controlling
the entire system.

The rest of this chapter is intended to guide you through the process of configuring your system
using Setup.

BIOS Setup

42

4-1 Starting BIOS Setup

The AMI BIOS is immediately activated when you power on the computer every time. The BIOS reads the system
information contained in the CMOS and begins the process of checking out the system and configuring it. After
finishing configuring the whole system, then BIOS will continue to seek an operating system on one of the disks,
launch then turn control over to the operating system.

While the AMI BIOS is in control, the Setup program can be activated in the way:

By pressing the <DEL> key when the following message appears briefly at the bottom of the screen during the
POST (Power On Self-Test).

43

4-2 Updating BIOS Setup

z Creating a bootable floppy disk

A、 DOS environment

Insert a 1.44 MB floppy disk into the drive.

At the DOS prompt, type:

format A:/S then press <Enter>.

B、 Microsoft® Windows® environment

Insert a 1.44 MB floppy disk into the floppy disk drive.

From your Windows desktop, click on Start, then select My Computer.

Select the 3 1/2 Floppy Drive icon.

Click File from the menu, and then select Format. A Format 3 1/2 Floppy Disk window appears.

If you are using Windows™, select “Create an MS-DOS startup disk” from the format options field, then click
Start.

z Move the latest BIOS file to the bootable floppy disk.

z Using “AMIFLASH.EXE” to update the BIOS

Update the BIOS using the AMIFLASH.EXE utility in DOS environment.

1. Visit the IWILL website (
the BIOS file to a bootable floppy disk.

2. At the DOS prompt, type the command line:
AMIFLASH / <filename>
where “filename” means the latest (or original) BIOS file that you copied to the bootable floppy disk. The
screen displays the status of the update process.

http://www.iwill.net ) to download the latest BIOS file for your motherboard. Save

Important

The BIOS information on the screen is for reference only. What you see on your screen may not be exactly the same
as shown.

Warning

DO NOT shut down or reset the system while updating the BIOS! Doing so may cause system boot failure!

44

3. When the BIOS update process is complete, the utility returns to the DOS prompt.

The AMI BIOS is immediately activated when you power on the computer every time. The BIOS reads the system
information contained in the CMOS and begins the process of checking out the system and configuring it. After
finishing configuring the whole system, then BIOS will continue to seek an operating system on one of the disks,
launch then turn control over to the operating system.

While the AMI BIOS is in control, the Setup program can be activated in the way:

By pressing the <DEL> key when the following message appears briefly at the bottom of the screen during the
POST (Power On Self-Test).

z Press <DEL> to enter SETUP

45

4-3 Using Setup

<F1> key again.

F10 Key Save and Exit

Home Go to top of screen

End Go to bottom of screen

Esc Exit

46

IMPORTANT

The BIOS does NOT automatically save values that you have modified. If you do not save your values before you
exit the BIOS Setup Utility, all your changes will be lost.

If after making and saving system changes with the BIOS Setup Utility, you discover that your computer is no longer
able to boot, the AMI BIOS supports an override, which will reset your system to the Failsafe defaults. If that fails, it
is possible to manually clear the present CMOS information through the "Clear CMOS Header" on the mother boa r d
(Refer to Jumper Settings for more information).

The best advice is to ONLY alter settings which you thoroughly understand. The default settings have been carefully
chosen by AMIBIOS to provide the maximum system performance and reliability. Even a slight change to the chipset
setup may cause potential and unpredictable failure to the system.

47

4-4 Main Menu

This is the first screen that is displayed when you enter the BIOS Setup Utility. Each tab lined on the top of the
screen represents each different menu. The following picture shows the main menu. Main menu shows the
information of BIOS version, date and ID; processor type, speed and count; system size. In addition, system time
