1-2 Chipset Overview

Built upon the functionality and the capability of the Intel E8870 (870)
chipset, the i2DMR-8G2/i2DMR-iG2 motherboard provides the performance

Introduction

and feature set required for high-end server platforms with configuration
options optimized for communications, presentation, storage, computation or
database applications. The Intel E8870 chipset consists of the following
four primary components: the Scalable Node Controller (SNC), Server I/O
Hub (SIOH), the Memory Repeater Hub for Synchronous Double Data Rate
Memory(MRH_D) and Scalability Port Switch (SPS) (*Note Below). Comple­mentary components include the I/O Hub Controller (Intel ICH4), the Firm­ware Hub (FWH), and the PCI Bus Bridge (P64H2).

The major bus groups are:

Processor system bus: supporting up to two processors and one Scalable
Node Controller (SNC), with a maximum operating frequency of 200
MHz@400 MT/s.

Rambus and SNC Interface: the Interconnection between the SNC and
Memory Repeater Hub (MRH-D), operating at a maximum frequency of 400
MHz.

Synchronous DDR Interface: interface between the MRH-D and up to four
DIMM sockets, operating at the operating clock frequency of 100 MHz per
branch channel.

Scalability Port (SP) Interface: a 400MHz, double-pumped, simultaneous bi­directional signaling (SBD) interface.

Hub Interface 2.0: interface between the SIOH and the P64H2 using 266
MHz strobes on a 16-bit wide data bus.

Hub Interface 1.5: interface between the SIOH and the ICH4 using 133 MHz
strobes on a 8-bit wide data bus.

Local Firmware Hub (LPC): Interface between the SNC and local firmware.

System Management Bus (SMBus): a subset of the I2C serial bus integrated
into the SNC, SPS, and SIOH.

(*Note: The Scalability Port Switch-SPS is not used in the i2DMR-8G2/iG2.)

1-10

Chapter 1: Introduction

Complementary Components include:

I/O Controller Hub (ICH4)

The ICH4 is the fourth-generation I/O Controller Hub subsystem that inte­grates many of the input/output functions of the chipset, including a two­channel ATA100 Bus Master IDE controller. The ICH4 also interfaces with
PCI and various communications ports. Nearly all communications between
the GMCH and the ICH4 takes place over the hub Interface, which is a 66
MHz/266 MB/s bus.

P64H2 PCI-X Hub (P64H2)

The P64H2 PCI-X Hub provides a 16-bit connection to the MCH for high­performance I/O capability and two 64-bit PCI-X interfaces.

1-3 Special Features

Recovery from AC Power Loss

BIOS provides a setting for you to determine how the system will respond
when AC power is lost and then restored to the system. You can choose
for the system to remain powered off (in which case you must hit the
power switch to turn it back on) or for it to automatically return to a power­on state. See the Power Lost Control setting in the Advanced BIOS Setup
section (Peripheral Device Configuration) to change this setting. The de­fault setting is Last State.

Introduction

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
i2DMR-8G2/i2DMR-iG2. All have an onboard System Hardware Monitor chip
that supports PC health monitoring.

Fan Status Monitor with Firmware/Software On/Off Control

The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin chassis fans are controlled by the power management func­tions.

1-11

SUPER i2DMR-8G2/i2DMR-iG2 User's Manual

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning

Introduction

function in the BIOS. This allows the user to define an overheat tempera­ture. When this temperature is exceeded, fans will speed up, and the
warning LED is triggered.

Auto-Switching Voltage Regulator for the CPU Core

The auto-switching voltage regulator for the CPU core can support up to
20A current and auto-sense voltage IDs ranging from 1.1V to 1.5V (*sup­ported by VRMs only). This will allow the regulator to run cooler and thus
make the system more stable.

1-5 ACPI Features

External Modem Ring-On

Wake-up events can be triggered by a device such as the external modem
ringing when the system is in the SoftOff state. Note that external modem
ring-on can only be used with an SSI compliant power supply.

1-6 Power Supply

As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors that
have high CPU clock rates.

The SUPER i2DMR-8G2/i2DMR-iG2 requires a 24-pin connector and two 4­pin 12V/15A connectors for CPU VRMs. Although most power supplies
generally meet the specifications required by the CPU, some are inadequate.
You should use one that will supply at least 500W of power, and an even
higher wattage power supply is recommended for high-load configurations.
Also your power supply must supply 2A for the Ethernet ports and the
E8870 chipset.

It is strongly recommended that you use a high quality power supply that
meets SSI EPS 12V 1U 500W PS Specification. To verify the status of SSI
compliance, please visit the web site at http://www.ssiforum.org/. Addi­tionally, in areas where noisy power transmission is present, you may
choose to install a line filter to shield the computer from noise. It is recom-

1-12

Chapter 1: Introduction

2-1 Static-Sensitive Devices

Electric-Static-Discharge (ESD) can damage electronic components. To pre­vent damage to your system board, it is important to handle it very carefully.
The following measures are generally sufficient to protect your equipment
from ESD.

Precautions

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

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

• Handle the board by its edges only; do not touch its components, periph­eral chips, memory modules or gold contacts.

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

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

• For grounding purposes, make sure your computer chassis provides ex­cellent conductivity between the power supply, the case, the mounting
fasteners and the motherboard.

Unpacking

The motherboard is shipped in antistatic packaging to avoid static damage.
When unpacking the board, make sure the person handling it is static protected.

2-2 Itanium2 Processor and Heatsink Installation

When handling the processor package, avoid placing direct
pressure on the label area of the fan. Also, do not place the

!

motherboard on a conductive surface, which can damage the
BIOS battery and prevent the system from booting up.

IMPORTANT: Always connect the power cord last and always remove it
before adding, removing or changing any hardware components. Make
sure that you install the processor into the CPU socket before you install
the CPU heat sink.

Note: To optimize the functionality and capability of the i2DMR-8G2/
i2DMR-iG2, we recommend that i2DMR-8G2/i2DMR-iG2 be installed in
Supermicro chassis only.

Warning: The heatsink on the MRH-D chip has been pre-installed by the

manufacturer. Please do not touch it. Turning the heatsink in a wrong
way will damage it and will void the manufacturer's warranty.

Note: Check the Supermicro web site for recommended memory modules:

http://www.supermicro.com/TECHSUPPORT/FAQs/Memory_vendors.htm

CAUTION

Exercise extreme care when installing or removing DIMM

modules to prevent any possible damage. Also note that the

memory is interleaved to improve performance (see step 1).

DIMM Installation

1. Insert either 4 or 8 identical DIMMs (-Memory of the same size and type)
into the memory slots, starting with DIMM1(J16), DIMM2(J13),
DIMM3(J11) & DIMM4(J9). (DIMM1-DIMM4 are the DIMM sockets colored
in blue.) If four more DIMMs are used, insert DIMM5(J15), DIMM6(J14),
DIMM7(J12) and DIMM8(J10) into the slots. (DIMM5-DIMM8 are the DIMM
sockets colored in black.) The memory scheme is interleaved, and you
must install four modules at a time, beginning with DIMM1, DIMM2,
DIMM3, DIMM4 (blue slots).

2. Insert each DIMM module vertically into its slot. Pay attention to the
notch along the bottom of the module to prevent inserting the DIMM
module incorrectly.

3. Gently press down on the DIMM module until it snaps into place in the
slot. Repeat for all modules (see step 1 above).

To modify the operation of the
motherboard, jumpers can be
used to choose between
optional settings. Jumpers
create shorts between two pins
to change the function of the
connector. Pin 1 is identified
with a square solder pad on
the printed circuit board. See
the motherboard layout pages
for jumper locations.
Note: On two pin jumpers,
"Closed" means the jumper is

Troubleshooting

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have
followed all of the procedures below and still need assistance, refer to the
‘Technical Support Procedures’ and/or ‘Returning Merchandise for Service’
section(s) in this chapter.

Note: Always disconnect the power cord before adding, changing
or installing any hardware components.

Notes:

1) It might take longer than usual (up to 40 seconds) to boot up the system.
(The larger the memory size is, the longer it will take to boot the
system.)

2) Please wait at least 10 seconds between power off and power on for
proper VRMs discharge.

3) The i2DMR-8G2/iG2 supports Limited ACPI functions (only the functions
of: “S0-Active”, and “S5-Complete power off” are supported).

4) The minimum power requirement is 500W and above. Also, two 4-pin
12V/15A power connectors are required for CPU Power Pods (VRMs).

5) There is no BIOS Recovery function available. Should a problem occur
after flashing BIOS, all six BIOS chips will have to be replaced.

Before Power On

1. Make sure no short circuits exist between the motherboard and chassis.

2. Disconnect all ribbon/wire cables from the motherboard, including those

for the keyboard and mouse.

3. Remove all add-on cards.

4. Install one CPU (making sure it is fully seated) and connect the chassis

speaker and the power LED to the motherboard. (Check all jumper
settings as well.)

No Power

1. Make sure no short circuits exist between the motherboard and the chas-

sis. (*Disconnect the AC plug from the power supply for more than 2
minutes to reset short circuit protection.)

2. Verify that all jumpers are set to their default positions.

3. Check that the 115V/230V switch on the power supply is properly set.

4. Connect the AC plug to the power supply, and turn the power switch on

3-1

SUPER i2DMR-8G2/i2DMR-iG2 User's Manual

and off to test the system.

5. The battery on your motherboard may be old. Check to verify that it still
supplies ~3VDC. If it does not, replace it with a new one.

No Video

1. If the power is on but you have no video, remove all the add-on cards
and cables.

2. Use the speaker to determine if any beep codes exist. Refer to the
Appendix for details on beep codes.

3. Make sure that the CPU is securely locked in the CPU socket.

4. Make sure that the 4-pin 12V/15A connector is used on the VRM Power
Pod.

5. Make sure that the CPU is completely inserted into the VRM Power Pod.
(*Please refer to Page 2-6 in Chapter 2.)

NOTE

If you are a system integrator, VAR or OEM, a POST diagnos-

tics card is recommended. For BIOS POST codes, refer to App.

A.

Memory Errors

1. Make sure the DIMM modules are properly and fully installed.

2. Determine if different speeds of DIMMs have been installed. It is recom­mended to use the same RAM speed for all DIMMs in the system.

3. Make sure you are using the correct type of ECC DDR-200 SDRAM (­utilizing DDR-266 operating at 200 MHz). EDO SDRAM and PC100/133
SDRAM are not supported.

4. Make sure all memory modules are fully seated in their slots. As an
interleaved memory scheme is used, you must install four or eight iden­tical memory modules at the same time, beginning with DIMM1­DIMM4(sockets colored in blue). (If eight DIMMs are used, install DIMM5­DIMM8((sockets colored in black.) (see Section 2-3).

5. Check the position of the 115V/230V switch on the power supply.

Losing the System’s Setup Configuration

1. Ensure that you are using a high quality power supply. A poor quality
power supply may cause the system to lose the CMOS setup informa­tion. Refer to Section 1-6 for details on recommended power supplies.

2. The battery on your motherboard may be old. Check to verify that it still
supplies ~3VDC. If it does not, replace it with a new one.

3. If the above steps do not fix the Setup Configuration problem, contact
your vendor for repairs.

AMIBIOS

4-1 Introduction

This chapter describes the AMIBIOS for the i2DRM-8G2/i2DRM-iG2. The AMI
ROM BIOS is stored in a Flash EEPROM and can be easily upgraded using a
floppy disk-based program. This chapter describes the basic navigation of
the AMI BIOS Setup Utility setup screens.

Starting BIOS Setup Utility

To enter the AMI BIOS Setup Utility screens, hit the <Delete> key while the
system is booting-up.

(*Note: In most cases, the <Delete> key is used to invoke the BIOS setup
screen. There are a few cases when other keys are used, such as <F1>,
<F2>, and so on.)

Each main BIOS menu option is described in this user’s guide. The Main
BIOS setup menu screen has two main frames. The left frame displays all
the options that can be configured. “Grayed-out” options cannot be config­ured. Options in blue can be configured by the user. The right frame dis­plays the key legend. Above the key legend is an area reserved for a text
message. When an option is selected in the left frame, it is highlighted in
white. Often a text message will accompany it.

(*Note: AMIBIOS has default text messages built in. Supermicro retains the
option to include, omit, or change any of these text messages.)

The AMI BIOS setup/utility uses a key-based navigation system called hot
keys. Most of the BIOS setup utility hot keys can be used at any time during
the setup navigation process. These keys include <F1>, <F10>, <Enter>,
<ESC>, <Arrow> keys, and so on.

(*Note: Options printed in Bold are default settings. )

Software Drivers and the Operating System

Installation

After all the hardware has been installed, you need to install the operating
system, and other software drivers. The necessary drivers are all
included on the Supermicro CDs that came packaged with your
motherboard.

5-1 Introduction to the EFI Platform

The EFI (Extensible Firmware Interface) Platform
is a new firmware architecture that provides
interface between the operating system and the
computer firmware (BIOS). It abstracts system
data specified in the system BIOS and translates
it into an object-oriented language that can be
easily accessed by the OS. It provides a rich
environment for system pre-installation. EFI
initializes chipset, buses, drivers, and locates OS
loaders. Once the EFI Firmware boots up the
system, it hands over the system operation to the
OS. When running in the background in the OS
environment, EFI still provides the system with
simple runtime services such as monitoring
firmware settings and system reset. Due to the
interoperability between the OS and the system
BIOS, EFI optimizes the performance of the 64-bit
Itanium2 systems.

10. When asked "Reset NVRAM to default value? (y/n), type "y" at the

prompt, if you want to reset all default values after flashing the BIOS.(*y:
This will reset your NVRAM which typically resets your boot options in EFI to
manufacturer defaults. If you previously added options to boot from CDROM
or Windows, these will disappear after NVRAM is reset, and in this case
you will have to re-add the options. n: This will leave NVRAM alone, thus,

your boot options will still remain the same as before BIOS flashed.) Type
"n" at the prompt if you want to keep the default values after BIOS flashing
as shown in the screen above.

11. When asked "Proceed with flash update? (y/n), type "y" at the prompt

to update the BIOS. Type "n" at the prompt if you do not want to update the
BIOS. If you type "y", the system will automatically update the BIOS file.

12. After BIOS is updated, you will be asked "Reset CMOS to default

values (will be done during the next boot?) y/n? as shown in the screen
below. (*y: if you want to reset BIOS to manufacturer’s default settings
during the next boot, or n: if you only want to update BIOS without resetting
it to manufacturer’s default settings.)

(*Please note that this reset will not affect EFI boot options.)

13. Then, you will be asked "Reset the system? y/n? Type "y" at the

prompt if you want to automatically reboot the system.

Brief instruction for IA64 OS (include Windows XP
64bit, Windows 2003 Enterprise 64bit, Red Hat
Linux 64 bit and SUSE Linux 64bit for Itanium)

Installation on IDE hard drive:

(*Note: The Itanium2 board does not have a floppy connector, so
the user cannot install Windows driver through a floppy device.
This procedure uses ramdisk to add the boot device driver in EFI so
that Windows OS will automatically pick up driver from there.)

1. Make sure that the driver for boot device (SCSI or RAID

controller) is supported by Itanium2.

2. Copy ramdisk.efi and driver files into a USB device (such
as USB pen). (*2.0 is recommended.)

3. Connect the USB device into one of USB ports and power on
the system. (Refer to Page 1-4 for the location of the USB
ports).

4. Once the system goes into the “EFI Boot Manager,” choose
“EFI Shell [Built-in]”

5. Under the “EFI Shell,” locate the USB device (for example:
fsx, fs0 or fs1...)

6. At the Shell command prompt, type: Shell> fsX: (*X=the num
ber of the file that your USB pen is located at.) (*This com
mand will change the directory from [Shell] to [fsX].)

7. At the new command prompt, type fsX:\> load ramdisk.efi
(*This command will create a virtual block inside the EFI. This
virtual block contains image of all files you have in your USB
device including boot device driver. This new block will be
the very last block under EFI shell. (*For example, if you
previously had total 6 blocks, the virtual block will be block 7
[blk7].)

8. Type: fsX:\> exit (*This command will exit from fsX device and
go back to “EFI Boot Manager.”)

9. Select “EFI Shell [Built-in]” again.

10: At the Shell command prompt, type: Shell> copy -r blkX: blk0:

*This command will copy the images from the virtual block (in
this example blk7) to block 0 (blk0). Now your driver is ready to
be used by the Windows OS.
