1-2 Chipset Overview

The Intel E7501 chipset is a high-performance chipset with a performance
and feature-set designed for mid-range, dual processor servers. The
E7501 chipset consists of four major components: the Memory Controller
Hub (MCH), the I/O Controller Hub 3 (ICH3), the PCI-X 64-bit Hub 2.0 (P64H2)
and the 82808AA Host Channel Adapter (VxB).

The MCH has four hub interfaces, one to communicate with the ICH3 and
three for high-speed I/O communications. The MCH employs a 144-bit wide
memory bus for a DDR-266 memory interface, which provides a total band­width of 3.2 GB/s. The ICH3 interface is a 266 MB/sec point-to-point con­nection using an 8-bit wide, 66 MHz base clock at a 4x data transfer rate.
The P64H2 interface is a 1 GB/s point-to-point connection using a 16-bit
wide, 66 MHz base clock at a 8x data transfer rate.

The ICH3 I/O Controller Hub provides various integrated functions, including
a two-channel UDMA100 bus master IDE controller, USB host controllers, a
System Management Bus controller and an AC'97 compliant interface.

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

1-3 Special Features

ATI Graphics Controller

The X5DMS-6GM/X5DMS-8GM has an integrated ATI video controller based
on the Rage XL graphics chip. The Rage XL fully supports sideband ad­dressing and AGP texturing. This onboard graphics package can provide a
bandwidth of up to 512 MB/sec over a 32-bit graphics memory bus.

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 Always On.

Introduction

1-4 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
X5DMS-6GM/X5DMS-8GM. The motherboard has an onboard System Hard­ware Monitor chip that supports PC health monitoring.

Onboard Voltage Monitors for the CPU Cores, Chipset
Voltage, +3.3V, +5V, +12V and +3.3V Standby

An onboard voltage monitor will scan these voltages continuously. Once a
voltage becomes unstable, a warning is given or an error message is sent
to the screen. Users can adjust the voltage thresholds to define the
sensitivity of the voltage monitor.

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 CPU and chassis fans are controlled by the power manage­ment functions. The thermal fan is controlled by the overheat detection
logic.

CPU Fan Auto-Off in Sleep Mode

The CPU fan activates when the power is turned on. It continues to operate
when the system enters Standby mode. When in sleep mode, the CPU will
not run at full power, thereby generating less heat.

CPU Overheat LED

JOH1 is a header used to connect to a CPU overheat LED. When the CPU
temperature becomes too high, both the overheat alarm and the warning
LED are activated.

System Resource Alert

This feature is available when used with Intel's LANDesk Client Manager
(optional). LDCM is used to notify the user of certain system events. For
example, if the system is running low on virtual memory and there is insuf­ficient hard drive space for saving the data, you can be alerted of the
potential problem.

Chapter 1: Introduction

1-11

Introduction

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 1.4V to 3.5V. This
will allow the regulator to run cooler and thus make the system more stable.

1-5 ACPI Features

ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible and abstract hardware interface that pro­vides a standard way to integrate power management features throughout
a PC system, including its hardware, operating system and application soft­ware. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives and printers. This also
includes consumer devices connected to the PC such as VCRs, TVs, tele­phones and stereos.

In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an oper­ating system-independent interface for configuration control. ACPI lever­ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with both Win­dows 2000 and Windows NT 5.0.

Microsoft OnNow

The OnNow design initiative is a comprehensive, system-wide approach to
system and device power control. OnNow is a term for a PC that is always
on but appears to be off and responds immediately to user or other re­quests.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start
blinking to indicate that the CPU is in suspend mode. When the user presses
any key, the CPU will wake-up and the LED will automatically stop blinking
and remain on.

SUPER X5DMS-6GM/X5DMS-8GM User’s Manual

1-12

Introduction

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a
system suspend button to make the system enter a SoftOff state. The
monitor will be suspended and the hard drive will spin down. Depressing
the power button again will cause the whole system to wake-up. During
the SoftOff state, the ATX power supply provides power to keep the re­quired circuitry in the system alive. In case the system malfunctions and
you want to turn off the power, just depress and hold the power button for
4 seconds. This option can be set in the Power section of the BIOS Setup
routine.

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 ATX 2.01 (or above) compliant power
supply.

Wake-On-LAN (WOL)

Wake-On-LAN is defined as the ability of a management application to re­motely power up a computer that is powered off. Remote PC setup, up­dates and asset tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The
motherboards have a 3-pin header (WOL) to connect to the 3-pin header on
a Network Interface Card (NIC) that has WOL capability. Note that Wake­On-LAN can only be used with an ATX 2.01 (or above) 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 X5DMS-6GM/X5DMS-8GM accommodates ATX power supplies.
Although most power supplies generally meet the specifications required by
the CPU, some are inadequate. You should use one that will supply at least
400W of power and includes the additional +12V, 8-pin power connector ­an even higher wattage power supply is recommended for high-load con­figurations. Also your power supply must provide 1.5A, which is needed
for the LAN

Chapter 1: Introduction

1-13

Introduction

port(s).

NOTE: Auxiliary 12v power (J15) is necessary to support Intel Xeon
CPUs. Failure to provide this extra power will result in the CPUs
becoming unstable after only a few minutes of operation. See
Section 2-5 for details on connecting the power supply cables.

It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.02 or above. It must also be SSI
compliant (info 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 recommended that you also install a
power surge protector to help avoid problems caused by power surges.

1-7 Super I/O

The disk drive adapter functions of the Super I/O chip include a floppy disk
drive controller that is compatible with industry standard 82077/765, a data
separator, write pre-compensation circuitry, decode logic, data rate selec­tion, a clock generator, drive interface control logic and interrupt and DMA
logic. The wide range of functions integrated onto the Super I/O greatly
reduces the number of components required for interfacing with floppy disk
drives. The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk
drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s.It also
provides two high-speed, 16550 compatible serial communication ports
(UARTs), one of which supports serial infrared communication. Each UART
includes a 16-byte send/receive FIFO, a programmable baud rate generator,
complete modem control capability and a processor interrupt system.
Each UART includes a 16-byte send/receive FIFO, a programmable baud
rate generator, complete modem control capability and a processor inter­rupt system. Both UARTs provide legacy speed with baud rate of up to

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

SUPER X5DMS-6GM/X5DMS-8GM User’s Manual

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.

Screws* (4)

*These screws are for mounting the
motherboard to the back panel of a
chassis that has four mounting holes
(as shown on right).

White pegs (4)

2. Insert the white pegs into the
black anchors. Do not force the
white pegs all the way in - only
about 1/3 of the way into the black
anchors.

3. Place a retention bracket in the
proper position and secure it by
pressing pegs into two of the retention
holes until you hear a *click*. The
clicking sound indicates that the peg is
locked and secured.

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.

Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of
chassis. Make sure the location of all the mounting holes for both the
motherboard and the chassis match. Although a chassis may have both
plastic and metal mounting fasteners, metal ones are highly recommended
because they ground the motherboard to the chassis. Make sure the metal
standoffs click in or are screwed in tightly. Then use a screwdriver to
secure the motherboard onto the motherboard tray.

Figure 2-2. Installing and Removing DIMMs

To Install: Insert module vertically and press down until it snaps into

place. Pay attention to the notches.

2-3 Installing DIMMs

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 (See Figure 2-2)

1. Insert the desired number of DIMMs into the memory slots, starting with

Bank 1. The memory scheme is interleaved so you must install two
modules at a time, beginning with Bank 1, then Bank 2, then Bank 3.

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).

Memory Support

The X5DMS-6GM/X5DMS-8GM can support up to 12 GB of ECC registered
DDR-266/200 (PC2100/1600) SDRAM memory. However, when a 400 FSB
CPU is used, DDR-266 will run at the speed of 200 MHz. PC100/133 SDRAM
is not supported.

Explanation of
Jumpers

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
on and "Open" means the
jumper is off the pins.

CMOS Clear

JBT1 is used to clear CMOS. Instead of pins, this jumper consists of con­tact pads to prevent accidentally clearing the contents of CMOS. To clear
CMOS, use a metal object such as a small screwdriver to touch both pads
at the same time to short the connection. Always remove the AC power
cord from the system before clearing CMOS.
Note: For an ATX power supply, you must completely shut down the sys­tem, remove the AC power cord and then short JBT1 to clear CMOS. Do

not use the PW_ON connector to clear CMOS.

Main Power Override

Instead of using the chassis
power on switch, you may close

your vendor for repairs.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also,
note that as a motherboard manufacturer, SuperMicro does not sell directly
to end-users, so it is best to first check with your distributor or reseller for
troubleshooting services. They should know of any possible problem(s)
with the specific system configuration that was sold to you.

NOTE

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

tics card is recommended. For I/O port 80h codes, refer to

App. B.

Memory Errors

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

2. Determine if different speeds of DIMMs have been installed and verify
that the BIOS setup is configured for the fastest speed of RAM used.
It is recommended to use the same RAM speed for all DIMMs in the
system.

3. Make sure you are using registered ECC DDR-266/200 (PC2100/1600)
type SDRAM. However, when a (*When a 400 MHz FSB CPU is used,
DDR-266 will run at the speed of 200 MHz.) EDO SDRAM and PC100/
133 SDRAM are not supported.

4. Check for bad DIMM modules or slots by swapping a single module be­tween two slots and noting the results.

5. Make sure all memory modules are fully seated in their slots. As an
interleaved memory scheme is used, you must install two modules at a
time, beginning with Bank 1, then Bank 2, then Bank 3 (see Section 2-

3).

6. Check the power supply voltage 115V/230V switch.

3-3

Chapter 3: Troubleshooting

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently
Asked Question' (FAQ) sections in this chapter or see the FAQs on our
web site (http://www.supermicro.com/techsupport.htm) before con­tacting Technical Support.

2. BIOS upgrades can be downloaded from our web site at
http://www.supermicro.com/techsupport/download.htm.

Note: Not all BIOS can be flashed depending on the modifications
to the boot block code.

3-3 Frequently Asked Questions

Question: What are the various types of memory that the X5DMS­6GM/X5DMS-8GM motherboard can support?

Answer: The X5DMS-6GM/X5DMS-8GM has six DIMM slots that support

184-pin, registered ECC DDR-266/200 (PC2100/1600) DDR-SDRAM modules.
(*When a 400 MHz FSB CPU is used, DDR-266 will run at the speed of 200
MHz.) It is strongly recommended that you do not mix memory modules of
different speeds and sizes. Unbuffered SDRAM, non-ECC memory and
PC100/133 SDRAM modules are not supported.

Question: How do I update my BIOS?

Answer: It is recommended that you do not upgrade your BIOS if you are

experiencing no problems with your system. Updated BIOS files are located
on our web site at http://www.supermicro.com. Please check our BIOS
warning message and the info on how to update your BIOS on our web

3-4

SUPER X5DMS-6GM/X5DMS-8GM User’s Manual

site. Also, check the current BIOS revision and make sure it is newer than
your BIOS before downloading. Select your motherboard model and down­load the BIOS file to your computer. Unzip the BIOS update file and you will
find the readme.txt (flash instructions), the flash.bat (BIOS flash utility) and
the BIOS image (xxxxxx.rom) files. Copy these files onto a bootable floppy
and reboot your system. It is not necessary to set BIOS boot block protec­tion jumpers on the motherboard. Finally, follow the readme text that has
been included in the unzipped files.

Question: What's on the CD that came with my motherboard?

Answer: The supplied compact disc has quite a few drivers and programs

that will greatly enhance your system. We recommend that you review the
CD and install the applications you need. Applications on the CD include
chipset drivers for Windows and security and audio drivers.

Question: Why can't I turn off the power using the momentary
power on/off switch?

Answer: The instant power off function is controlled in BIOS by the Power

Button Mode setting. When the On/Off feature is enabled, the motherboard

will have instant off capabilities as long as the BIOS has control of the
system. When the Standby or Suspend feature is enabled or when the
BIOS is not in control such as during memory count (the first screen that
appears when the system is turned on), the momentary on/off switch must
be held for more than four seconds to shut down the system. This feature
is required to implement the ACPI features on the motherboard.

3-4 Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is
required before any warranty service will be rendered. You can obtain
service by calling your vendor for a Returned Merchandise Authorization
(RMA) number. When returning to the manufacturer, the RMA number
should be prominently displayed on the outside of the shipping carton, and
mailed prepaid or hand-carried. Shipping and handling charges will be ap­plied for all orders that must be mailed when service is complete.

BIOS

4-1 Introduction

This chapter describes the PhoenixBIOS™ Setup utility for the X5DMS-6GM/
X5DMS-8GM. The Phoenix ROM BIOS is stored in a flash chip and can be
easily upgraded using a floppy disk-based program.

Note: Due to periodic changes to the BIOS, some settings may have been
added or deleted and might not yet be recorded in this manual. Please refer
to the Manual Download area of the Supermicro web site
<http://www.supermicro.com> for any changes to BIOS that may not be
reflected in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®,
and PS/2® compatible computers. The PhoenixBIOS flash chip stores the
system parameters, such type of disk drives, video displays, etc. in the
CMOS. The CMOS memory requires very little electrical power. When the
computer is turned off, a back-up battery provides power to the BIOS flash
chip, enabling it to retain system parameters. Each time the computer is
powered-on the computer is configured with the values stored in the BIOS
ROM by the system BIOS, which gains control at boot-up.

How To Change the Configuration Data

The CMOS information that determines the system parameters may be
changed by entering the BIOS Setup utility. This Setup utility can be ac­cessed by pressing the <Delete> key at the appropriate time during system
boot, see below.

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory
test. As the memory is being tested, press the <Delete> key to enter the
main menu of the BIOS Setup utility. From the main menu, you can access
the other setup screens, such as the Security and Power menus. Begin­ning with Section 4-3, detailed descriptions are given for each parameter
setting in the Setup utility.

Appendix A

BIOS POST Messages

During the Power-On Self-Test (POST), the BIOS will check for problems. If a problem
is found, the BIOS will activate an alarm or display a message. The following is a list
of such BIOS messages.

Failure Fixed Disk

Fixed disk is not working or not configured properly. Check to see if fixed disk is
attached properly. Run Setup. Find out if the fixed-disk type is correctly identified.

Stuck key

Stuck key on keyboard.

Keyboard error

Keyboard not working.

Keyboard Controller Failed

Keyboard controller failed test. May require replacing keyboard controller.

Keyboard locked - Unlock key switch

Unlock the system to proceed.

Monitor type does not match CMOS - Run SETUP

Monitor type not correctly identified in Setup

Shadow Ram Failed at offset: nnnn

Shadow RAM failed at offset nnnn of the 64k block at which the error
was detected.

System RAM Failed at offset: nnnn

System RAM failed at offset nnnn of in the 64k block at which the error
was detected.

Extended RAM Failed at offset: nnnn Extended memory not
working or not configured properly at offset nnnn.

System battery is dead - Replace and run SETUP

The CMOS clock battery indicator shows the battery is dead. Replace the
battery and run Setup to reconfigure the system.

SUPER X5DMS-6GM/X5DMS-8GM User’s Manual

A-2

System CMOS checksum bad - Default configuration used

System CMOS has been corrupted or modified incorrectly, perhaps by an
application program that changes data stored in CMOS. The BIOS installed Default
Setup Values. If you do not want these values, enter Setup and enter your own
values. If the error persists, check the system battery or contact your dealer.

System timer error

The timer test failed. Requires repair of system board.

Real time clock error

Real-Time Clock fails BIOS hardware test. May require board repair.

Check date and time settings

BIOS found date or time out of range and reset the Real-Time Clock. May require
setting legal date (1991-2099).

Previous boot incomplete - Default configuration used

Previous POST did not complete successfully. POST loads default values and
offers to run Setup. If the failure was caused by incorrect values and they are
not corrected, the next boot will likely fail. On systems with control of wait
states, improper Setup settings can also terminate POST and cause this error on
the next boot. Run Setup and verify that the waitstate configuration is correct.
This error is cleared the next time the system is booted.

Memory Size found by POST differed from CMOS

Memory size found by POST differed from CMOS.

Diskette drive A error

Notes

Appendix B: BIOS POST Codes

B-1

This section lists the POST (Power On Self Test) codes for the PhoenixBIOS. POST
codes are divided into two categories: recoverable and terminal.

Recoverable POST Errors

When a recoverable type of error occurs during POST, the BIOS will display
an POST code that describes the problem. BIOS may also issue one of the
following beep codes:

1 long and two short beeps - video configuration error
1 continuous long beep - no memory detected

Terminal POST Errors

If a terminal type of error occurs, BIOS will shut down the system. Before
doing so, BIOS will write the error to port 80h, attempt to initialize video and
write the error in the top left corner of the screen.
The following is a list of codes that may be written to port 80h.

* If the BIOS detects error 2C, 2E, or 30 (base 512K RAM error), it displays an additional
word-bitmap (xxxx) indicating the address line or bits that failed. For example, “2C
0002” means address line 1 (bit one set) has failed. “2E 1020" means data bits 12
and 5 (bits 12 and 5 set) have failed in the lower 16 bits. The BIOS also sends the
bitmap to the port-80 LED display. It first displays the checkpoint code, followed by
a delay, the high-order byte, another delay, and then the loworder byte of the error.
It repeats this sequence continuously.
